Job Title:
AI Research Scientist

Salary:
£120k-£200k + Equity

Company Description:
London-based applied AI robotics lab founded by the Magic Pony co-founder

Job Description:
Join an elite engineering team from Amazon AGI and InstaDeep building general-purpose robotics for the real world. Rather than iterating in simulation, you will develop 3D perception and robot learning models (VLA/RL) grounded in data from actual supermarket deployments, bridging the gap between cutting-edge AI research and physical impact.

Location:
London, UK

Why this role is remarkable:
- Work directly under the founder of Magic Pony (acquired by Twitter for ~$150M) and a world-class team from Amazon, Imperial, and Cambridge.
- Access unique, high-fidelity data from robots already deployed in messy, real-world human environments rather than just lab-based simulations.
- Benefit from significant early-stage equity and competitive compensation while shaping the UK's leading applied physical AI startup from the ground floor.

What you will do:
- Develop and deploy cutting-edge 3D perception models to help robots understand and navigate chaotic, dynamic human environments.
- Research and implement robot learning approaches, including Vision-Language-Action (VLA) models and Reinforcement Learning for complex manipulation.
- Publish original research at top-tier venues like ICRA, CoRL, and NeurIPS while ensuring models are robust enough for real hardware.

The ideal candidate:
- Holds a PhD or equivalent research depth with 5+ years of experience in AI robotics, computer vision, or reinforcement learning.
- Demonstrates a proven track record of deploying sophisticated models onto physical hardware, overcoming sensor noise and real-world edge cases.
- Possesses strong software engineering skills, with the ability to prototype rapidly in Python and ship production-grade code without constant oversight.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

This high-agency role involves shaping the core product used by major global financial aggregators.

Location:
San Francisco, Austin, NYC, Remote

Why this role is remarkable:

- Build core platform infrastructure including authentication, webhooks, rate limiting, and vendor-agnostic abstraction layers to ensure system reliability and scalability.
- Develop in-house feature extraction pipelines and productionize ML models for income categorization, anomaly detection, and automated financial insights.

The ideal candidate:
- Senior or Staff-level engineer with deep experience building data-centric products from infancy, specifically involving complex Postgres schema design and SQL migrations.
- Practical experience consuming ML models via APIs/SDKs and building the supporting feature pipelines, though this is an engineering rather than research-focused role.
- Proficient in TypeScript and modern backend architectures, with a strong bias toward shipping and experience working in fast-paced, early-stage startup environments.

Job Title:
Founding Full-Stack + AI Engineer

Salary:
£80k-£95k + Equity

Company Description:
FCA-authorized AI-native insurance platform rebuilding commercial broking from first principles

Job Description:
Join the strongest team in UK InsurTech to build the "Revolut for commercial insurance." As a founding engineer, you will architect an AI-driven system replacing manual workflows with computational infrastructure. You'll move from intake to bind, shipping production AI that has already reduced quoting times from sixty minutes to seven.

Location:
Remote, UK

Why this role is remarkable:
- Work directly with an elite founding team including an exited SaaS founder and former leads from Acturis and Flock.
- Join a company with massive traction: 47 signed partners and £125m in addressable premium within the first twelve months.
- Tackle a uniquely asymmetric opportunity in a £15B+ market with high regulatory moats and complex technical integration challenges.

What you will do:
- Architect and build core broking workflows including market routing, quote generation, and automated renewals.
- Design and deploy production AI systems for multi-agent orchestration, document extraction, and call analysis.
- Build and maintain critical evaluation frameworks and testing pipelines to ensure the reliability of LLM applications.

The ideal candidate:
- A strong generalist with professional experience across TypeScript, React/Next.js, and Python-based AI services.
- An applied AI builder who has successfully shipped multi-agent systems or complex LLM applications into production.
- A high-agency engineer who thrives in ambiguity, ships 80% solutions quickly, and thinks in user workflows rather than tickets.

Job Title:
Founding Marketer - Head of Growth

Salary:
£50k-£80k + Equity

Company Description:
Proprietary dental-tech startup co-founded by Skin + Me co-founder (£70M+ ARR)

Job Description:
You will join as the first marketing hire to disrupt the global dental sensitivity market. Working directly with founders who have previously scaled D2C brands to £70M+ ARR, you will build the growth engine from scratch. You will own the entire customer journey, from paid acquisition to retention strategy.

Location:
London, UK

Why this role is remarkable:
- Rare opportunity to join a category-disrupting consumer health brand at the founding stage with a proprietary, clinically superior formulation.
- Build alongside a proven founding team with deep experience scaling D2C giants like Skin + Me and Life Supplies.
- Significant founding-level equity in a business targeting a massive global market currently dominated by legacy incumbents like Sensodyne.

What you will do:
- Design and execute the full-funnel growth strategy across Meta, TikTok, and paid social ahead of the summer 2026 launch.
- Build out the D2C tech stack including Shopify integration, email/SMS flows, and conversion rate optimization (CRO) frameworks.
- Manage the entire unit economics model, taking full ownership of CAC, ROAS, and LTV to ensure sustainable, high-growth scaling.

The ideal candidate:
- 2-5 years of hands-on D2C growth experience, ideally from a high-growth UK challenger brand like Huel, Surreal, or Grind.
- AI-native operator who defaults to using automation and AI tools to move faster and execute high-quality work independently.
- Entrepreneurial "founder wiring" with the ability to build and iterate rapidly without needing a pre-defined brief or large team.

Job Title:
Product Engineer

Salary:
Not Disclosed

Company Description:
YC S20 AI-native life sciences platform streamlining drug development

Job Description:
You will architect a GxP execution system that unifies fragmented legacy tools like ELN and LIMS into a single, high-performance platform. By building critical primitives for automation and verifiable audit trails, you will help biotech and pharma companies reduce paperwork by 80% and accelerate life-saving drug launches. This is a high-ownership role for a systems-thinking product obsessionist.

Location:
London, UK or Research Triangle Park, USA

Why this role is remarkable:
- Work on a mission-critical platform used by 50+ regulated companies including Beckman Coulter and Paradromics to save lives through faster therapy development.
- Join an elite, high-intensity YC S20 team where you have absolute ownership over entire platform areas and move from idea to production in days.
- Solve profoundly difficult systems-design problems at the intersection of AI, complex workflow automation, and rigorous regulatory compliance (GxP).

What you will do:
- Architect and own critical primitives including data abstractions for life sciences, complex workflow engines, and verifiable audit trails.
- Design and implement AI-native interfaces that radically increase scientist productivity and automate 90% of quality review cycles.
- Lead weekly missions to identify the most critical platform objectives, defining solutions from first principles and shipping production-ready TypeScript code.

The ideal candidate:
- You are a pathologically product-obsessed engineer who can balance high-level UI aesthetics with low-level systems architecture.
- You have a proven track record of shipping complex projects and possess strong systems-design instincts regardless of your specific tech stack.
- You thrive in high-standard, in-person environments and are a self-directed, first-principles thinker who values impact over bureaucratic process.

Job Title:
Founding AI Engineer — Agent Runtime

Salary:
$100,000 – $150,000 + Equity

Company Description:
$3.5M-funded San Francisco AI startup founded by serial entrepreneurs from LeanData and Chronicled

Job Description:
As the first engineering hire, you will build a policy-driven runtime that executes high-stakes B2B commercial workflows. Unlike simple LLM wrappers, you'll architect a deterministic execution layer where models negotiate real contracts and protect revenue. Reporting to a veteran CTO, you'll own the agent pipeline, state management, and safety guardrails.

Location:
San Francisco, USA

Why this role is remarkable:
- Significant ownership as the first engineering hire with 1% - 1.5% equity and direct access to founders who have scaled multiple successful B2B companies.
- Work on a mission-critical "decision-making" AI system that governs 80/20 commercial outcomes rather than just generating text for chat interfaces.
- Backed by $3.5M in funding from previous investors and led by a CTO whose prior systems verify 80% of US prescription drug returns.

What you will do:
- Design and evolve a multi-stage agent pipeline covering intent classification, context assembly, reasoning, and response generation as a cohesive system.
- Build the event-driven runtime that governs agent lifecycles, state management, and policy enforcement to ensure safety by construction.
- Develop a robust evaluation framework to define correctness and catch regressions before they reach enterprise customers in high-stakes environments.

The ideal candidate:
- Proven experience building production-grade LLM systems where reliability was non-negotiable and simple prompting was insufficient for the task.
- Strong systems engineering background with proficiency in typed languages like TypeScript, Go, or Rust and an ability to think in complex types.
- Deep understanding of the boundary between model flexibility and deterministic enforcement, with experience in retrieval, context management, and multi-turn reasoning.

Job Title:
Data Infrastructure Engineer

Salary:
$180k-$240k + Equity

Company Description:
Pear VC-backed AI context infrastructure startup founded by Visa and LinkedIn engineering leaders

Job Description:
You will architect the core systems enabling AI agents to reason over fragmented enterprise data. Designing distributed storage, real-time query engines, and semantic knowledge graphs, you’ll solve deep technical challenges at the intersection of high-throughput systems and knowledge representation for Fortune 500 deployments as a foundational engineering hire.

Location:
San Mateo, USA

Why this role is remarkable:
- Work directly with founders who built Visa's payment infrastructure and LinkedIn's 900M-member Knowledge Graph to define the next layer of the agentic AI stack.
- Tackle "engine-level" problems rather than just integrating APIs, including building custom distributed storage and semantic inference layers from scratch.
- Secure a high-impact, seed-stage role with a competitive $180k-$240k base and meaningful early equity in a company already deploying with major enterprises.

What you will do:
- Design and implement distributed storage layers and consistency protocols optimized for graph-structured data at massive scale.
- Architect high-performance query execution engines capable of performing real-time semantic inference across billions of data relationships.
- Build robust ingestion pipelines that discover and normalize domain knowledge across dozens of heterogeneous, fragmented enterprise data sources.

The ideal candidate:
- Deep systems-level proficiency in Java, C++, or Rust with a focus on multithreading, distributed consistency models, and consensus protocols.
- Proven track record building core infrastructure components like query engines, database internals, or large-scale data partitioning systems.
- Strong architectural intuition for high-QPS environments and the ability to navigate complex trade-offs between availability, latency, and fault tolerance.

Job Title:
Founding Engineer - Full Stack

Salary:
$200k+ + Equity

Company Description:
VC-backed pre-construction AI startup funded by top-tier investors in PlanGrid and BuildingConnected

Job Description:
Join a founding team of Cornell alumni and ex-McKinsey founders automating the $13 trillion construction industry. As a Founding Engineer, you will own the platform end-to-end, building AI agents that transform weeks of manual bid comparisons into hours. You'll architect high-scale Node/TypeScript services and ship a critical Electron-based desktop application.

Location:
San Francisco, USA

Why this role is remarkable:
- Ship to production daily for general contractors who are already using the platform in live project cycles to manage multi-million dollar bids.
- Backed by the same elite VCs who invested in construction-tech unicorns like PlanGrid and BuildingConnected, offering massive category-ownership potential.
- High-impact founding equity and $200k+ total compensation in a role where you influence every architectural decision from day one.

What you will do:
- Architect and build core Node.js/TypeScript services, deciding when to utilize microservices versus monoliths for complex construction data models.
- Lead the development of a native-feel Electron desktop app for Mac/Windows featuring offline sync, file system access, and automated updates.
- Design the integration backbone connecting to Procore, SharePoint, and Excel using asynchronous job systems, webhooks, and robust retry logic.

The ideal candidate:
- Has 4+ years of professional experience as a full-stack engineer, ideally as a founder or an early engineer at a high-growth startup.
- Deeply proficient in the modern JS/TS stack including Node.js, React, and PostgreSQL, with a proven ability to manage GCP or Supabase infrastructure.
- Thrives in 0→1 environments where they can context-switch between high-level architectural design and deep-diving into database indexes or CSS components.

Title:
Co-founding Head of Product / CPO ($200k-$250k + Equity) at Pre-seed AI automation startup

Job Title:
Co-founding Head of Product / CPO

Salary:
$200k-$250k + Equity

Company Description:
Pre-seed AI automation startup

Job Description:
As a co-founding leader, you will own the product strategy and GTM positioning for an AI-driven platform replacing legacy IT service management. You will define the initial beachhead wedge, navigate competitive landscapes against industry incumbents, and secure the first ten enterprise customers by transforming deterministic manual workflows into automated resolutions.

Location:
San Francisco, USA

Why this role is remarkable:
- Significant co-founder equity stake (5-15%) offering true ownership and influence over the company's foundational culture and trajectory.
- Massive market opportunity disrupting a multi-billion dollar sector dominated by legacy tools that manage tickets rather than resolving problems.
- Backed by deeply committed technical founders in a high-growth space where LLMs have unlocked new capabilities for deterministic execution.

What you will do:
- Define and execute the product roadmap, shifting the focus from manual ticket triage to automated, Slack-based resolution workflows.
- Lead go-to-market efforts and competitive positioning to displace established incumbents like ServiceNow and Jira Service Management.
- Partner directly with the technical co-founders to win the first ten enterprise customers and build a repeatable sales motion.

The ideal candidate:
- Proven track record shipping enterprise workflow automation products in ITSM, Security Ops, IAM, or DevOps at a successful startup.
- Experience taking a product from zero to meaningful ARR with the GTM instinct required to navigate early-stage enterprise sales.
- Background at major enterprise incumbents or high-growth startups, with the hunger to return to a pre-seed environment and build from scratch.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Founding Engineer

Salary:
$180k-$220k + Equity

Company Description:
$1.8M pre-seed AI startup backed by Innovation Endeavors and OpenAI/Instacart angels transforming the $750B food manufacturing industry

Job Description:
As a Founding Engineer, you will build the AI agents replacing fragmented legacy systems in the massive food manufacturing sector. You'll move across the full stack—from engineering RAG systems for product catalogues to developing computer-use agents for complex compliance automation—directly impacting how food reaches tables across the US.

Location:
San Francisco, USA

Why this role is remarkable:
- Work directly with founders from Instacart, Bain, and Stanford who bring deep domain expertise from a 4th-generation food manufacturing family business.
- Massive market opportunity in a $750B industry still operating on pen and paper, with high-signal backing from Eric Schmidt's fund and industry leaders.
- True founding ownership with 0.5%–2% equity and the chance to shape every major technical and product decision from day zero.

What you will do:
- Design and deploy backend systems that ingest and process hundreds of PDFs from customer ERPs and CRMs using semantic analysis.
- Build and iterate on AI agents using Anthropic and Gemini to automate 100-page compliance documents and end-to-end sales workflows.
- Develop a performant, modern frontend and infrastructure using Kotlin, Spring Boot, React, and Terraform on GCP.

The ideal candidate:
- A proven builder who has shipped real-world products and prioritizes pragmatism and speed over architectural purity.
- Highly autonomous engineer comfortable with "boring" proven tech like Kotlin and Postgres to solve complex, high-stakes industrial problems.
- San Francisco-based professional ready for a high-impact, hybrid role (3 days/week) with a strong bias toward shipping 80% solutions today.

Who are Jack & Jill?:

- Join a high-growth Series A startup already deploying with Fortune 500 leaders across the insurance, travel, and technology sectors.

What you will do:
- Design and deploy state-of-the-art models to extract structured domain knowledge from heterogeneous and disconnected enterprise data sources.
- Develop, evaluate, and scale AI Data Graphs and semantic systems that provide the reasoning foundation for high-precision autonomous agents.
- Fine-tune large and small language models (LLMs/SLMs) with domain-specific context to ensure production-grade accuracy and reduced inference costs.

The ideal candidate:
- Holds an MS or PhD in Computer Science or ML with 4+ years of hands-on experience in NLP, knowledge extraction, or retrieval.
- Demonstrates a proven track record of shipping and maintaining ML models in production environments, specifically using BERT, LLMs, or embedding-based retrieval.
- Possesses a builder mindset with previous startup experience, thriving in fast-paced environments where they can influence core infrastructure from day one.

- Solve complex on-device inference challenges through a unique partnership with Mumsnet and Nothing Technology to launch child-safe hardware.

What you will do:
- Design and train computer vision and NLP models to detect harmful content across varied UI contexts and video feeds.
- Optimize model performance for low-latency, on-device execution using quantization, TFLite, and ONNX Runtime on Android devices.
- Build robust evaluation suites and error-analysis workflows to minimize false positives while maintaining high recall for critical safety scenarios.

The ideal candidate:
- 2+ years of experience in applied ML or research, ideally with a background in object detection (YOLO) and transformer architectures (ModernBERT/RoBERTa).
- Proven ability to ship production-grade ML systems, balancing scientific rigor with the practical trade-offs of a fast-moving startup environment.
- Hands-on expertise in model optimization and threshold tuning, specifically for on-device inference where memory and speed are constrained.

Company Description:
$20M Series A cloud security startup backed by FirstMark and Accel

Job Description:
Join a high-calibre engineering team building the future of cloud intrusion detection. You will develop intelligent canary tripwires that protect massive clients like Riot Games and Docker. Working directly with the founders, you'll ship daily to process billions of events using a powerful stack of C#, .NET Core, and AWS.

Location:
London, UK

Why this role is remarkable:
- Join one of the UK's most exciting startups, recently raising a $20M Series A led by FirstMark and featured on Sifted's 2025 "London Startups To Watch."

- Collaborate face-to-face with technical founders and high-profile customers to translate security research into robust, production-ready detection features.
- Take ownership of end-to-end delivery in a low-bureaucracy environment, shipping code daily and maintaining infrastructure as code for planetary-scale event processing.

The ideal candidate:
- Proven track record of shipping software at scale or in critical environments, ideally within a product-focused company or high-growth startup.
- Strong proficiency in any object-oriented language; while we use C#, we value architectural instinct and engineering quality over specific language syntax.

Job Title:
AI/ML Research Engineer

Salary:
$150k-$350k + Equity

Company Description:
YC W26 enterprise AI startup building the world's fastest computer-use agents

Job Description:
You will join a 4-person founding team to build high-speed AI agents that automate legacy enterprise workflows. Moving beyond slow screenshot-to-VLM loops, you will develop agents that pre-train on interface navigation to achieve 5x faster execution. This role blends cutting-edge research in agentic orchestration with rapid production deployment.

Location:
San Francisco, USA

Why this role is remarkable:
- Join a Y Combinator W26 company at the ground floor, working directly with founders on the core technology that defines the product's intelligence.
- Solve a massive enterprise bottleneck by building deterministic, self-healing agents that operate complex legacy software without APIs or structured data interfaces.
- High-impact environment where your research in reasoning models and vision-language architectures is shipped to production for real enterprise customers immediately.

What you will do:
- Research and implement novel agentic architectures for GUI automation using multi-agent coordination, memory, and context management.
- Build and evaluate reasoning pipelines—including chain-of-thought and reflexion loops—that maintain reliability under distribution shifts in enterprise environments.
- Develop interface pre-training methods and VLM-based screen understanding to enable deterministic execution and self-healing for automated enterprise agents.

The ideal candidate:
- Early-career researcher (0-4 years) with a Master's or PhD in CS/AI from a top-tier program or a track record at a premier research lab.
- Strong engineering skills in Python, PyTorch, and agentic frameworks like LangGraph or AutoGen, with the ability to move from paper to prototype rapidly.
- Deep curiosity for computer-use agents and GUI understanding, evidenced by top-tier publications (NeurIPS, ICLR, CVPR) or significant production-grade AI projects.

Working directly with repeat founders who sold companies to TikTok, you will build end-to-end software that processes real transactions, reviews patient records, and generates measurable economic value.

Location:
London, UK

Why this role is remarkable:
- Learn directly from two exited founders (former Google and TikTok) who have built and sold AI companies over the last decade.
- Gain deep frontier AI knowledge by building real-world production systems rather than just experimenting with wrapper tools or reading papers.
- High-impact variety: you will solve diverse problems across multiple industries every 4-9 months, offering faster growth than a single-product company.

What you will do:
- Design and build end-to-end AI software systems, from initial client scoping to shipping production-ready code that handles live transactions.
- Collaborate directly with leadership teams at client sites, including PE funds and global distributors, to integrate AI into their core workflows.
- Rapidly iterate on frontier models and tooling to determine what actually scales in high-stakes business environments versus what is just hype.

The ideal candidate:
- 4+ years of full-stack software engineering experience with a proven track record of shipping production-grade systems, not just features.
- Demonstrated agency and initiative through significant side projects, open-source contributions, or a history of high performance in non-technical fields.
- Strong business curiosity and communication skills to effectively translate complex technical solutions for non-technical leadership and stakeholders.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

The ideal candidate:
- 3-10+ years of experience in product engineering with strong fundamentals in distributed systems, networks, and infrastructure.
- Proven ability to ship high-quality developer tools or infrastructure products with a relentless focus on API design and user experience.
- Deep curiosity and a bias for action; prior experience in payments domain (3DS, card networks, or compliance) is a significant advantage.

Job Title:
Senior Technical Recruiter

Salary:
Up to £75k + Equity

Company Description:
a16z and YC-backed AI startup transforming the $350B secondhand fashion supply chain

Job Description:
You will own end-to-end technical hiring for Engineering and Product teams at a hyper-growth Series B startup. Beyond delivery, you will architect the talent function—designing interview frameworks, sourcing playbooks, and building custom recruiting tools using Claude Code. This is a high-velocity role for a builder who thrives in early-stage environments.

Location:
London, UK

Why this role is remarkable:
- Join a Series B startup that has raised ~$50M from premier investors including a16z, Y Combinator, and HV Capital while tripling in size year-on-year.
- Direct mentorship from a Head of Talent who scaled functions at Procore and Mews, with a clear pathway to eventually owning the talent function.
- Be at the forefront of AI-native recruiting by building actual tools and automations with Claude Code rather than just using basic prompts for outreach.

What you will do:
- Drive the full recruitment lifecycle for technical roles in London, from initial role design and sourcing to final offer closing and onboarding.
- Partner deeply with Engineering and Product leaders to define high-quality hiring bars, push back on vague briefs, and implement structured scorecards.
- Architect the foundational talent infrastructure, including leveling guides and AI-integrated workflows that will define how the company scales globally.

Job Title:
Founding Go-To-Market Lead

Salary:
$100,000–$140,000 + Equity

Company Description:
Blackbird Ventures-backed AI assistant for the wealth management industry

Job Description:
As the first US hire for this high-growth fintech startup, you will spearhead the expansion of an AI-native system of record for financial advisers. Having already proven the model in three international markets, you will write the US playbook, closing early customers and bridging the gap between advisers and product development.

Location:
San Francisco, USA

Why this role is remarkable:
- You will be the founding US employee, reporting directly to founders and holding significant influence over the expansion strategy of a product with proven international traction.
- The company is backed by Blackbird Ventures ($2.7M raised) and led by founders who deeply understand the industry's friction points from firsthand experience.
- You will receive meaningful founding-level equity in a startup that is shifting highly-regulated professionals from manual documentation to automated AI-driven workflows.

What you will do:
- Build and execute the end-to-end US go-to-market strategy, covering everything from ICP definition and outbound prospecting to demos and onboarding.
- Serve as the primary face of the brand at industry events and within RIA and broker-dealer communities to build authentic, high-trust relationships.
- Act as the critical feedback loop between US customers and the international product team to shape localization, compliance templates, and priority features.

The ideal candidate:
- You have 3–6 years of experience in the US financial advice industry as an adviser, paraplanner, or in a client-facing fintech sales role.
- You possess a deep understanding of the US regulatory landscape and the technical documentation workflows required for RIA and broker-dealer compliance.
- You are a builder with a high-ownership mindset who is an active AI power user, comfortable operating without a pre-existing sales playbook.

Salary:
£80k–£100k+ + Equity

Company Description:

Job Description:
You will own the AC power architecture for the UK’s largest synthetic fuel plant, designing systems that convert renewable energy into carbon-neutral methane. By bridging the gap between direct air capture and high-power electrolysis, you will eliminate technical bottlenecks to help the company scale its modular plant technology 1000x within two years.

What you will do:
- Take full ownership of AC power system architecture, including power distribution, protection strategies, and panel design for modular chemical plants.
- Design and integrate 3-phase systems, pumps, and heaters across direct-air-capture units and alkaline electrolysers.
- Lead panel certification activities (CE/UKCA) and contribute to functional safety via HAZOPs, FMEAs, and SIL/PL determination.

The ideal candidate:
- 5+ years of industrial electrical design experience working with power systems, industrial machinery, or complex process environments.
- Expert proficiency in electrical CAD tools such as Solidworks Electrical, EPLAN, or AutoCAD for producing detailed schematics.
- Deep understanding of functional safety standards (IEC 61508) and experience navigating the Machinery and Low Voltage Directives.

Job Title:
Data Scientist, AI Agents

Salary:
£60–100k + Meaningful Equity

Company Description:
AI-native data platform founded by former Secondmind and Sylvera leaders, building autonomous agents to structure institutional financial data.

Job Description:
You will act as a super-IC managing a fleet of AI agents to turn 100,000+ unstructured financial PDFs into high-fidelity queryable datasets. Sitting between data science and engineering, you will design agentic workflows, encode human judgment into validation logic, and ensure total data reliability for global asset managers and banks.

Location:
London, UK

Why this role is remarkable:
- Work directly with founders including a former Sylvera founding member and a Cambridge ML expert who co-founded Secondmind.
- Join a high-output, 5-person team in Old Street where you'll automate yourself out of tasks daily to tackle increasingly complex financial data challenges.
- Take ownership of the entire delivery function with direct exposure to institutional customers and the frontier of agentic AI workflows.

What you will do:
- Design and maintain data pipelines using AI agents, prompt chains, and human-in-the-loop checkpoints to extract data at scale.
- Build and encode sophisticated validation logic in Python and SQL to catch edge cases that standard LLM extractions miss.
- Manage the end-to-end data quality lifecycle, serving as the final line of defense for data accuracy before it reaches tier-one financial clients.

The ideal candidate:
- 1–5 years of experience as a Data Scientist or Analytics Engineer with deep proficiency in Python, SQL, and terminal-based workflows.
- AI-native professional who uses tools like Cursor or Claude Code for production-level work and understands agentic patterns over simple prompting.
- A data-obsessed builder who has experience wrangling messy, unstructured datasets and feels a personal responsibility for data integrity and precision.

Job Description:
Join a high-intensity team disrupting the $280B insurance market as an early sales hire.

- High-reward culture offering top-quartile OTE, uncapped commissions, and zero-barrier support including full relocation and all meals covered.

What you will do:
- Build and aggressively expand target account lists to drive outbound pipeline through cold calls, email automation, and LinkedIn.
- Own the initial qualification process by running first discovery calls with enterprise insurance carriers to identify high-value revenue opportunities.
- Partner directly with the CEO and SVP of Sales to build the company’s outbound engine and develop new enterprise GTM playbooks.

The ideal candidate:
- At least 1-2+ years of experience in an SDR, BDR, or GTM role with a proven track record of generating outbound pipeline.
- Relentless drive and comfort with high-volume outbound activity, including the ability to handle 100+ cold calls per day and live conversations.
- High-agency operator with a competitive background who thrives in an in-person, high-intensity San Francisco environment.

Job Title:
Founding Game Designer

Salary:
£80k-£110k + Equity

Company Description:
AI learning world startup led by former Google and Synthesia leaders

Job Description:
You will be the first game designer for a revolutionary generative learning world built in Godot 4. Designing for children aged 6–10, you will move beyond static levels to create the systems, constraints, and progression mechanics that govern an emergent, voice-driven 2D world featuring an evolving AI companion character.

Location:
London, UK

Why this role is remarkable:
- Shape a completely new genre of "generative learning" inspired by *The Diamond Age*, moving digital play from passive consumption to active, personalized exploration.
- Join a world-class founding team: the CEO previously raised $25M+ for Neoplants, and the CPTO was the first product hire at $1B+ unicorn Synthesia.
- High-impact founding role with significant equity, allowing you to define the design language and visual identity for a product bridging the gap between AI and childhood.

What you will do:
- Design the exploration systems, pacing, and progression mechanics that make a procedurally generated world feel coherent and emotionally resonant.
- Prototype rapidly using AI tools to generate assets and test emergent player behaviors within a voice-first, interactive environment.
- Establish the foundational design frameworks and provide strong input on the visual art direction to ensure a safe, engaging experience for young children.

The ideal candidate:
- Proven track record of shipping interactive products where you owned core systems design, economy, or progression mechanics.
- Strong systems thinker who can design rules for emergent behavior rather than relying on hand-crafted, authored content.
- Creative generalist comfortable working in Godot 4 and designing for non-adult audiences with a curiosity for how children play and learn.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Backend/Infrastructure Engineer

Salary:
£150k + Equity

Company Description:
Well-funded pre-Series A AI infrastructure startup building the operational memory layer for production agents

Job Description:
As the first engineering hire, you will architect the core storage and retrieval systems that allow AI agents to possess persistent memory. You'll build high-performance infrastructure serving execution history in the hot path, ensuring agents learn from past runs. This is a high-ownership role for a systems expert ready to ship production-grade code.

Location:
London, UK

Why this role is remarkable:
- Join as the first engineering hire with significant equity and direct influence over the foundational architecture of a high-growth AI infrastructure startup.
- Tackle the "goldfish memory" problem in AI by building a system that achieves sub-80ms retrieval speeds, faster than the blink of a human eye.
- Work in-person with an elite founding team in Canary Wharf, building the essential plumbing that makes agentic frameworks like LangGraph and CrewAI production-ready.

What you will do:
- Design and implement the core storage and retrieval architecture to handle execution history and shared state across massive agent fleets.
- Build and maintain the high-performance SDK that early design partners use to integrate persistent memory into their production AI stacks.
- Profile system bottlenecks and optimize latency to maintain consistent sub-80ms performance while scaling the infrastructure to 100x current load.

The ideal candidate:
- 4-8 years of experience building latency-sensitive production systems using performance-oriented languages like Rust, Go, or C++.
- Deep understanding of distributed systems and storage trade-offs, specifically with databases like Redis, RocksDB, or DynamoDB in high-traffic environments.
- Proven track record of taking vague problem statements from concept to production-ready systems without needing pre-defined specifications or hand-holding.

As the first dedicated marketing hire, you'll transition the company from stealth R&D to real-world scale, owning everything from high-level strategy to hands-on execution across multiple product launches.

Location:
San Francisco, USA

Why this role is remarkable:
- Lead a true 0→1 growth build at the intersection of autonomous systems and applied AI, taking over the function from the CEO.
- Backed by an elite roster of investors including Draper Associates, Precursor Ventures, and the founders of Crunchbase and Republic.
- Massive variety and impact as you develop unique growth playbooks for a platform that spins up and operates multiple companies in parallel.

What you will do:
- Design and execute the full-funnel growth strategy to convert prospects into revenue across multiple agent-led products.
- Personally launch and optimize campaigns across X, Reddit, and SEO while managing the entire marketing automation and attribution stack.
- Run a structured experimentation program to identify unconventional distribution channels that cut through the noise of the crowded AI market.

The ideal candidate:
- 5+ years of experience marketing frontier products at early-stage startups (0→1 or 1→10 scale), preferably within the AI/ML space.
- Deep technical proficiency in SEO fundamentals and hands-on execution of paid social campaigns on high-signal platforms like X and Reddit.
- Exceptional storytelling and positioning skills with the ability to translate complex autonomous systems into compelling narratives for both technical and non-technical audiences.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Technical Lead / CTO

Salary:
Not Disclosed

Company Description:
Mission-driven London startup building national security and critical infrastructure software

Job Description:
As the first technical hire, you will architect and build a modular, interoperable platform to detect and respond to cross-domain security threats. You will design a system that synthesizes signals from cyber, physical, and information domains, translating complex real-world national resilience problems into robust, production-ready software for high-consequence environments.

Location:
London, UK

Why this role is remarkable:
- Full technical ownership of a mission-critical platform from a completely blank slate, with direct influence on the company's product direction.
- Opportunity to build foundational technology for national security and defense, tackling complex problems that existing siloed systems cannot solve.
- Meaningful equity is available, offering a co-founder level stake or early employee options for a truly vested interest in the mission.

What you will do:
- Design and implement a scalable system architecture that integrates multiple external SME technologies and disparate data sources.
- Work directly with the CEO to prototype and build the synthesis layer that produces decision-ready intelligence for government clients.
- Own the entire engineering lifecycle, from selecting the tech stack and tooling to hands-on development and future team building.

The ideal candidate:
- 5–10 years of experience in hands-on engineering with strong architectural judgment in integration-heavy or distributed systems.
- Proven ability to build robust software from first principles, staying deep in the code while navigating high-level product ambiguity.
- Strong motivation for mission-driven work in national resilience, with the existing legal right to work in the UK.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Head of Operations

Salary:
$180,000–$250,000

Company Description:
$25M San Francisco nonprofit AI safety and biosecurity talent accelerator

Job Description:
Join a high-growth talent accelerator as the first operational hire, building the backbone for a $25M organization protecting humanity from transformative AI risks. You will triple the team from 7 to 25, establish a new San Francisco headquarters, and launch a founder residency program, owning everything from recruiting to complex international grant systems.

Location:
San Francisco, USA

Why this role is remarkable:
- Exceptional autonomy with no COO above you, allowing you to design and build every operational function from scratch using your own judgment.
- High-impact mission with $25M in funding already secured and a proven track record of training 7,000+ people for roles at Anthropic, DeepMind, and government safety institutes.
- A rare "building" opportunity to own a once-in-a-career project, including a full HQ buildout and the creation of a residency for frontier AI entrepreneurs.

What you will do:
- Lead the end-to-end buildout of a new San Francisco headquarters, including lease negotiation, layout design, and project management.
- Scale the organization from 7 to 25 employees within 12 months by building the recruiting, people ops, and HRIS functions from zero.
- Architect and manage global grant disbursement systems and visa logistics for a rotating residency of 10-20 international entrepreneurs.

The ideal candidate:
- Proven experience scaling operations at a fast-growth startup, ideally moving from ~10 to 50 employees, with a bias toward action over process.
- Versatile operator capable of managing diverse functions including recruiting, vendor management, immigration law, and facility buildouts simultaneously.
- High-agency problem solver with the ability to learn complex domains fast and a desire to return to the "scrappy chaos" of early-stage building.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Full-Stack AI Engineer

Salary:
£60k-£90k + Bonus

Company Description:
Profitable, privately funded UK property lender specializing in bridging and development finance

Job Description:
As the founding engineering hire, you will build and own two greenfield products from the ground up: an internal loan management system integrating HubSpot CRM and a custom investor portal. Working directly with the founders within a new Innovation department, you will define the technical architecture and drive product-led growth.

Location:
London, UK

Why this role is remarkable:
- Take total ownership as the first engineering hire in a profitable, fast-moving business that is just launching its dedicated technology division.
- Influence the company’s trajectory by building a bespoke internal loan ecosystem and an external investor portal from scratch rather than maintaining legacy code.
- Work in a high-trust environment with direct access to co-founders and a technically proficient team, skipping the corporate ticket queue for real impact.

What you will do:
- Architect and develop an end-to-end loan management system that connects HubSpot CRM with underwriting, completions, and loan monitoring workflows.
- Design and launch a secure investor portal to streamline fundraising, deal updates, and high-stakes investor communications.
- Make foundational technical decisions on the stack and infrastructure while collaborating with the Innovation team to translate business requirements into software.

The ideal candidate:
- Possesses 1-5 years of professional full-stack development experience with a track record of building and shipping high-quality, functional products.
- Demonstrates strong conscientious engineering practices and the ability to work independently in a greenfield environment without needing a predefined spec.
- Has experience or interest in fintech, financial services, or CRM integrations (like HubSpot), combined with a desire for hybrid work in Camden, London.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Backend Engineer

Salary:
Not Disclosed

Company Description:
London-based voice AI startup building real-time interpretation infrastructure

Job Description:
As the second backend engineer, you will work directly with the technical founder to build the production-grade infrastructure powering real-time voice interpretation. You will own the core architecture from scratch, designing a unified API platform that preserves tone and intent across multiple languages, ensuring high concurrency and system reliability at scale.

Location:
London, UK

Why this role is remarkable:
- Direct impact as the second backend hire, working alongside the technical founder to design and build core infrastructure from the ground up rather than maintaining legacy systems.
- Tackle one of the hardest problems in voice AI: real-time interpretation that preserves tone and intent, moving beyond robotic word-for-word translation.
- Join a technical founding team with a working product already featuring multiple modes (translate, share, connect, meet) ready for production-grade scaling.

What you will do:
- Architect and maintain a unified AI API platform to package internal capabilities for high-scale external use cases.
- Design and implement critical backend systems for billing, usage metering, and complex real-time voice room infrastructure.
- Build and optimize high-concurrency data pipelines and cloud infrastructure on Azure, incorporating automated scaling and load balancing.

The ideal candidate:
- 4-8 years of experience building and scaling production-grade backend systems with a high degree of autonomy and technical ownership.
- Strong proficiency in Python and solid experience with distributed systems, cloud infrastructure (specifically Azure), and database design.
- Experience with real-time systems and high-concurrency design, with the ability to build monitoring and analytics dashboards from scratch.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Company Description:
Venture-backed AI startup with $8.5M seed funding building agentic systems for global freight forwarding

Job Description:
Join an elite team automating complex, exception-heavy workflows in logistics.

Working directly with founders, you’ll shape the architecture and iterate rapidly to solve mission-critical problems for global freight giants.

Location:

Why this role is remarkable:

What you will do:
- Prototype and ship full-stack features using React, TypeScript, and Python, moving from idea to production deployment at high velocity.
- Design and optimize scalable APIs and cloud architectures using Temporal for orchestration and PostgreSQL to support sophisticated AI agents.
- Work directly with customers to understand real-world logistics bottlenecks and translate those insights into intuitive, performant UI/UX solutions.

The ideal candidate:
- 4-8 years of experience building production-grade systems at high-growth tech companies, with strong proficiency in Python and modern React.
- Proven track record of shipping AI/ML features, specifically working with LLM orchestration, autonomous agents, or OpenAI/Anthropic integrations.
- Exceptional product intuition and high agency; you are a self-driven builder who prioritizes user experience and first-principles thinking over technical over-engineering.

Job Title:
Founding Software Engineer

Salary:
Not Disclosed

Company Description:
Pre-seed airport operations AI startup backed by Entrepreneur First (EF)

Job Description:
As the first engineering hire, you will build the technical core of a real-time orchestration platform for airport ground operations. You will design systems that reconcile noisy live signals into a canonical operational state, automating complex resource allocation and conflict resolution to prevent the cascading delays that cost the aviation industry billions annually.

Location:
London, UK

Why this role is remarkable:
- Solve high-stakes systems problems like real-time state machines and dependency-aware recomputation for live airport environments rather than building generic CRUD apps.
- Join a founding team with deep operational expertise from Formula 1, the FIA, and Lufthansa, backed by the EF Fall 2025 cohort.
- Gain massive employee #1 ownership, working directly with founders to move from architecture to implementation while seeing your code drive physical operations on the airport ramp.

What you will do:
- Design and implement real-time data processing pipelines and conflict detection state machines using TypeScript, Python, and Convex.
- Build deterministic allocation and assignment logic that continuously recomputes the best use of staff and equipment under volatile real-world constraints.
- Develop causal graph orchestration systems to handle delay propagation and multi-tenant operational logic across complex task windows.

The ideal candidate:
- Has 2-3 years of experience in high-growth startups building correctness-sensitive backend systems, event-driven architectures, or workflow engines.
- Demonstrates a strong grasp of algorithms and invariants, with the ability to own the full lifecycle of complex systems from architecture to production debugging.
- Is a prolific builder with a portfolio of side projects or open-source contributions who thrives in ambiguous, founder-level ownership environments.

Job Title:
Full Stack Engineer (Founding Team)

Salary:
£60k-£80k + Equity

Company Description:
Cambridge-based agentic AI platform founded by Alexa's former speech lead and the Chair of the UK Government AI Council

Job Description:
As the first full-time engineering hire, you will transform a working prototype into a production-grade SaaS for enterprise customers. You will build secure backends for sensitive data and craft intuitive interfaces for complex AI outputs. Working alongside a veteran founding team, you will shape the technical foundation of a platform that scales human insight.

Location:
Cambridge, UK

Why this role is remarkable:
- Join as the first full-time engineer with significant equity and a clear path to technical leadership as the founding team scales.
- Work with an elite founding team including the CTO who led Alexa's NLU at Amazon and the co-founder of CognitionX.
- Build a platform that uses voice AI and agentic workflows to enhance human expertise rather than replacing it, solving a critical bottleneck in enterprise AI adoption.

What you will do:
- Take a functional AI prototype to production-grade, establishing the deployment pipelines, monitoring, and observability required for enterprise reliability.
- Design and own the full-stack UI/UX, creating interfaces that make high-volume AI-generated insights legible and actionable for non-technical users.
- Implement secure data pipelines and architecture to meet rigorous enterprise security standards including GDPR and ISO 27001/42001 compliance.

The ideal candidate:
- 3-8 years of experience shipping production web applications, with strong proficiency in React/TypeScript and Python/FastAPI.
- Proven ability to design database structures and manage cloud infrastructure, preferably within the AWS ecosystem.
- A product-focused engineer who has thrived in small startup environments and is comfortable making independent technical decisions across the entire stack.

This is a high-agency role where your code directly translates into faster patient treatment.

Location:

Why this role is remarkable:

- Own the full lifecycle of deployments, ensuring long-term stability while turning bespoke client learnings into scalable product capabilities.

The ideal candidate:
- Strong proficiency in TypeScript and React with demonstrable experience integrating LLMs and AI into production-grade environments.
- A "breaker and builder" mindset with the social intelligence to navigate complex client environments and ambiguous technical requirements independently.
- Readiness for regular travel to UK and US healthcare sites, combined with a desire to work in a high-intensity, mission-driven office culture.

Job Title:
Founding Deployed Engineer

Salary:
$180K – $250K + Equity

Company Description:
$8.5M Seed-stage AI startup backed by OpenAI and Blackstone C-suite

Job Description:
You will take proprietary agentic AI capabilities into the field, deploying solutions for trillion-dollar asset managers and global developers. As a founding engineer, you own the gap between technical prototypes and production value, building Python-based agents and automation pipelines that accelerate institutional real estate projects from concept to completion.

Location:
New York City, USA

Why this role is remarkable:
- Rare opportunity to join a high-velocity founding team backed by top-tier venture capital and industry giants like the C-suite from Blackstone and OpenAI.
- Direct impact on the physical world by automating complex workflows for the world’s largest digital infrastructure, energy, and industrial projects.
- Accelerated founder’s track where you gain radical autonomy and 0.3%–0.8% equity at a company redefining a multi-trillion-dollar asset class.

What you will do:
- Work directly with institutional real estate stakeholders to translate ambiguous requirements into scoped, production-grade AI agent solutions.
- Design and ship end-to-end agentic workflows using Python, LangGraph, and browser/voice agents to automate complex acquisitions and development cycles.
- Lead live customer pilots and iterate rapidly based on field feedback to convert deployment learnings into reusable product patterns and playbooks.

The ideal candidate:
- 2-6 years of professional experience with a proven track record of shipping production AI/ML systems rather than just experimental prototypes.
- High-level technical proficiency in Python and modern AI frameworks, combined with the soft skills to communicate tradeoffs to non-technical C-suite executives.
- A "builder" mindset characterized by extreme ownership, a bias toward velocity, and the ability to thrive in an intense, on-site startup environment.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Pre-seed AI-native advertising infrastructure startup serving Fortune 500 clients

Job Description:
As a Full-Stack Engineer at this early-stage startup, you will build the first two-sided marketplace connecting AI publishers with brands.

Location:

Why this role is remarkable:
- First Mover Advantage: You will be defining an entirely new category of advertising infrastructure specifically designed for the generative AI and LLM era.

What you will do:
- Build and iterate on advertiser-facing dashboards and publisher integration tools using React, TypeScript, and FastAPI.
- Design and implement high-throughput, low-latency ad-serving APIs that process millions of daily impressions across a distributed infrastructure.
- Manage real-time data pipelines and analytics on ClickHouse and PostgreSQL to provide advertisers with instant performance metrics like CPC and ROAS.

The ideal candidate:
- Full-Stack Proficiency: Strong production experience with Python (Django/FastAPI), React, and PostgreSQL; ClickHouse or OLAP database experience is a major plus.
- Startup Veteran: Proven track record of building zero-to-one products in fast-paced environments where you successfully owned features from migration to deployment.
- Technical Depth: Deep understanding of distributed systems, concurrency, and performance optimization for high-traffic APIs and real-time data streaming.

Founding Marketer

Salary:
Up to £50k + 0.5% Equity

Company Description:
Pre-seed AI insurtech backed by Haatch and Aviva/Founders Factory (£950k raised)

Job Description:
Join a high-growth London startup as the first dedicated marketing hire, taking full ownership of our brand presence. You will orchestrate our content engine, manage our industry-leading podcast for accountants, and drive distribution across social channels. This is a high-agency role working directly with founders to disrupt the £5B commercial insurance market.

Location:
London, UK

What you will do:
- Manage the end-to-end lifecycle of our podcast and social media engine, repurposing long-form content into viral clips and high-performing LinkedIn posts.
- Orchestrate the marketing strategy by identifying when to execute tasks in-house versus managing specialized freelancers for design, copywriting, or video production.

The ideal candidate:
- A high-potential graduate or early-career marketer (0-3 years) who is "deeply online" and understands the nuances of social algorithms and internet culture.

Job Title:
Product Engineer

Salary:
£110K–£170K + Equity

Company Description:
Stealth-stage London startup building the world's first autonomous technology deployment platform

Job Description:
You will build the orchestration layer that automates enterprise software roll-outs for a $13 trillion industry. Moving fluidly across React and Python/FastAPI, you will transform complex configuration workflows into simple, intuitive experiences for non-technical users. This is a high-agency role where your success is measured by customer deployment outcomes, not just code.

Location:
London, UK

Why this role is remarkable:
- Exceptional traction with over $2M ARR already secured in stealth from global enterprises like Parsons and Ferrovial.

Job Title:
Full-Stack Growth Builder

Salary:
Not Disclosed

Company Description:
$50M Series B a16z and YC-backed B2B marketplace for secondhand fashion

Job Description:
As a super-IC on a high-velocity growth team, you will reinvent customer lifecycle marketing using AI as your default toolkit. You'll architect adaptive CRM systems, build reseller engagement tools, and design rigorous experimentation frameworks. This is a technical building role focused on driving measurable, causal impact on retention and global supply chain efficiency.

Location:
London, UK

Why this role is remarkable:
- Join a talent-dense team backed by top-tier investors like a16z, Y Combinator, and the founders of Depop and Shopify during a period of triple-digit year-on-year growth.
- Move beyond static marketing journeys to architect AI-native systems that dynamically optimize messaging, timing, and channel prioritization using real-time user signals.
- Report directly to a VP of Growth with a massive scaling track record at Deliveroo, operating in a low-ego environment where velocity and high ownership are the core values.

What you will do:
- Design and maintain smart CRM systems and automated content generation workflows using AI (Claude/Cursor) to deliver hyper-personalized user experiences.
- Build end-to-end tooling for resellers, such as cross-listing features, to drive long-term platform stickiness and bridge the gap between B2B and consumer markets.
- Implement rigorous experimentation frameworks, utilizing causal inference and holdouts to quantify the true incremental revenue impact of lifecycle initiatives.

The ideal candidate:
- A technical "builder" profile proficient in SQL and AI-coding tools, capable of shipping production-quality systems and navigating large, messy datasets without engineering support.
- Deeply analytical with a strong grasp of experimentation ethics, including lift testing and fatigue management, to balance short-term optimization with long-term trust.
- Product-minded innovator who prefers building autonomous, learning systems over manually executing traditional marketing campaigns or static lifecycle journeys.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Staff AI Engineer

Salary:
£120k-£150k + Equity

Company Description:
$6.5M Seed-stage Agentic AI platform led by Salesforce Ventures

Job Description:
As the most senior AI hire, you will architect a sophisticated multi-agent orchestration layer for regulated financial institutions. Moving beyond simple wrappers, you'll solve high-stakes technical challenges in document intelligence, automated underwriting, and hallucination detection. This is a hands-on leadership role shaping the future of a platform already trusted by marquee enterprise banks.

Location:
London, UK

Why this role is remarkable:
- Lead AI strategy at a startup that scaled from MVP to paying enterprise customers like Metro Bank in under a year, targeting a $36 trillion industry.

Job Title:
Founding Head of Growth

Salary:
£70k-£90k + Equity

Company Description:
Seed-stage AI-native fintech backed by Raba, Factorial, and Revolut operators

Job Description:
You will lead customer acquisition end-to-end for a proptech-fintech hybrid reimagining rental operations. Reporting to the CEO, you’ll build a compounding growth engine across London, cracking distribution to agency-using landlords through structured experiments, geographic density strategies, and offline referral loops. This is a high-ownership role at the center of a #108bn market opportunity.

Location:
London, UK

Why this role is remarkable:
- Direct impact on a #108bn market with a product offering 47% contribution margin and a 0.6-month CAC payback.
- Backed by high-profile investors and operators from Revolut, BVNK, and AWS, with founders from Goldman Sachs and JP Morgan.
- High-ownership "founding" position where cracking distribution is the primary moat against competitors in a changing regulatory landscape.

What you will do:
- Design and execute structured experiments across unconventional channels like licensing registers, mail drops, and referral partner networks.
- Build geographic density in specific London boroughs to trigger local reputation effects and frictionless referral loops.
- Manage the end-to-end growth stack, from defining KPIs and clean attribution to conducting monthly NPS checks for product-led growth.

The ideal candidate:
- 5-8+ years of growth experience, with at least 2 years in a high-growth B2C marketplace or fintech environment like Revolut.
- Proven track record of running disciplined experiments with documented hypotheses and pass/fail thresholds.
- Comfortable with a hybrid "boots on the ground" approach, combining digital funnel analysis with offline relationship building and partner management.

Company Description:
Aviva-backed and Founders Factory-incubated insurance infrastructure startup

Job Description:
As the first technical hire, you will architect and build an AI-native platform transforming insurance capacity management.

This is a high-impact, co-builder role shaping the technical DNA of a category-defining fintech.

What you will do:
- Architect and build the core platform from scratch, establishing engineering best practices, security foundations, and compliance-aware system design.
- Develop the canonical data model and integrate external data sources to power an intelligent, AI-native capacity allocation layer.
- Collaborate directly with the CEO to translate commercial goals into technical execution while shipping production code and onboarding early customers.

The ideal candidate:
- Proven track record as a founding or early engineer in a startup environment, with the ability to build and ship products from the ground up.
- Deep full-stack development expertise combined with practical AI/ML experience, specifically in document extraction, NLP, or LLM integrations.
- Strong background in regulated industries like fintech or insurance, with experience building complex multi-party marketplace or orchestration systems.

Job Title:
Founder’s Associate

Salary:
Not Disclosed

Company Description:
Post-Series A PropTech startup building an AI-first operating system for property management

Job Description:
Join a fast-growing, 45-person team as a junior co-founder to the leadership team. You will drive high-priority initiatives across fundraising, commercial strategy, and operations. By handling autonomous AI integration for the UK property market, you'll solve complex administrative burdens and help scale a category-defining company while working directly with ex-Goldman Sachs and Cevian Capital founders.

Location:
London, UK

Why this role is remarkable:
- Work directly with founders from Goldman Sachs and Cevian Capital, gaining unprecedented exposure to every strategic lever of a scaling business.
- Join a post-Series A company that is already live and growing fast across the UK, moving at an uncommon pace to redefine a legacy industry.
- This is a high-agency "junior co-founder" role where you own outcomes rather than just managing tasks, with significant equity upside.

What you will do:
- Support end-to-end fundraising and investor relations, including board prep, data room management, and drafting investment memos and updates.
- Own commercial operations and client relationship coordination, identifying ways to systematize the sales pipeline and contract processes.
- Lead ad hoc strategic projects that lack a home, ranging from high-level hiring initiatives to operationalizing new AI-driven product features.

The ideal candidate:
- 2–4 years of experience in management consulting (MBB), investment banking, venture capital, or a high-growth startup environment.
- Exceptionally strong analytical and communication skills, with a 1st degree from a top-tier university and the ability to produce polished work under pressure.
- High-agency operator who thrives in ambiguity, moves without being asked, and is comfortable working on-site five days a week in London.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Job Title:
Chief of Staff (Founding Operator)

Salary:
$90k + $10k-$50k Profit Share + Equity

Company Description:
AI-native M&A advisory firm backed by founders with 8-9 figure exits and former Investment Bank MDs.

Job Description:
You will be the engine of an AI-native M&A firm, bridging the gap between operations, GTM, and product. Working directly with an exited founder, you will modernize the $1M-$50M revenue market by managing end-to-end deal processes through proprietary conversational AI agents, automating the operational grind to focus on closing high-value transactions.

Location:
Remote, USA

Why this role is remarkable:
- Work alongside a world-class investor group including former MDs from top-tier investment banks and PE fund managers who are actively modernizing the M&A space.
- Leverage proprietary conversational AI agents, Sage and Sterling, which handle the operational heavy lifting, allowing you to move with unprecedented speed and efficiency.
- Rare opportunity to join as a Founding Operator with 1% equity and an accelerated vesting schedule that is three times shorter than the industry standard.

What you will do:
- Manage 5-10 simultaneous sell-side M&A processes, from building 30-page information memorandums to orchestrating multi-stage outbound buyer campaigns.
- Translate customer feedback into actionable product improvements, working directly with engineers to spec and ship features for the AI-native platform.
- Build and optimize the company's internal operating system, driving OKRs, tracking KPIs, and developing no-code automations to scale the business methodically.

The ideal candidate:
- Proven experience in a fast-paced startup environment (Series A-C) or as a founder; you possess the "startup DNA" to operate without a playbook.
- Deep understanding of the M&A lifecycle, including LOIs, due diligence, and financial modeling, ideally gained from a boutique advisory or brokerage firm.
- Technical fluency with no-code tools and automations; you are a high-agency operator who builds systems rather than just following existing manual workflows.

Company Description:
$2.3M seed-funded AI cybersecurity startup transforming vulnerability management

Job Description:
You will join as a core engineer building an AI engine that prioritizes critical security threats. Working alongside a founder from HackerOne, you will bridge the gap between automated scanning and real-world attacker logic, developing sophisticated ML pipelines and agentic AI features to help organizations defend themselves at scale.

Location:
London, UK

Why this role is remarkable:
- Work directly with a founder who led Hacker R&D at HackerOne and managed programs for the UK Ministry of Defence and FTSE 100 companies.

Job Title:
Senior Frontend Engineer

Salary:
$180k-$220k + Equity

Company Description:
Series A VC-backed context infrastructure startup for agentic AI

Job Description:
Join a small, senior team founded by former Visa and LinkedIn executives building the Graph Semantic Layer for the AI era. As a founding product engineer, you will own the frontend architecture and user experience, creating complex data visualizations that enable autonomous agents to reason over fragmented enterprise data with precision at scale.

Location:
San Mateo, USA

Why this role is remarkable:
- Work directly with founders who built world-scale data infrastructure at Visa and LinkedIn, including one of the industry's largest production knowledge graphs.

- Enjoy high autonomy and equity in a senior 3-person frontend team, shaping a product already being deployed by major enterprises in insurance and travel.

What you will do:
- Lead the frontend development of the Graph Semantic Layer, making key architectural decisions and ensuring UI consistency across all surfaces.
- Build sophisticated data visualization tools using React and TypeScript to help users interact with complex graph and network data.
- Partner with co-founders and design partners to translate user research into intuitive interfaces for high-stakes enterprise AI operations.

The ideal candidate:
- 5+ years of experience with deep React/TypeScript expertise and a background in building data products like dashboards or analytics tools.
- Proficiency with data visualization libraries such as D3, Recharts, or ECharts and experience working in fast-paced startup environments.
- A product-minded engineer comfortable contributing to backend APIs (Python/Java) and driving technical decisions without heavy external direction.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

Company Description:
Azzurri Group-backed hospitality data SaaS scaling across 1,500+ venues

Job Description:
As the most senior individual contributor, you will serve as the technical right hand to the Head of Engineering.

Job Title:
Technical Co-Founder

Salary:
Not Disclosed + Equity

Company Description:
Antler-backed AI startup building the distribution intelligence layer for the UK’s £11T asset management industry

Job Description:
You will lead the technical architecture and build for an agentic intelligence platform that tells fund distribution teams who to target and what to say. This is an equal partnership role owning everything from high-scale data ingestion pipelines to LLM orchestration, serving a validated market of mid-tier UK asset managers.

Location:
London, UK

Why this role is remarkable:
- Significant equity stake (35-45%) as an equal partner with a domain-expert founder from BlackRock and Schroders.
- Backed by the Investment Association (IA) and Antler, with SEIS assurance secured and a £1.5M seed round pipeline established.
- Direct market access through a signed design partnership with a UK fund manager starting May 5th and three EU-based pilots.

What you will do:
- Ship the agentic data pipeline to synthesize 10-20 financial data sources into actionable intelligence for distribution teams.
- Design and architect a multi-tenant dashboard and daily briefing product using Next.js, TypeScript, and modern AI orchestration.
- Establish enterprise-grade security and auditability (SOC 2 readiness) required to sell into FCA-regulated financial institutions.

The ideal candidate:
- Full-stack expert with production experience in data engineering, web scraping, and scaling ETL pipelines for messy public data.
- Hands-on experience building agentic AI systems (Claude/OpenAI APIs) where LLM orchestration is the core product, not a wrapper.
- Founder DNA with a security-first mindset, comfortable in a high-ambiguity, London-based environment that ships code weekly.

Who are Jack & Jill?:
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

The ideal candidate:
- Proven experience building and scaling production data platforms using Python, SQL, and modern orchestration tools like Dagster or Airflow.
- Strong architectural fluency in cloud-native environments, specifically across AWS and GCP with practical Infrastructure-as-Code experience.

Senior Backend Engineer

Salary:
$180k-$220k + Equity

Company Description:
High-growth SF cloud financial data platform founded by industry experts with a massive 35k+ community and multi-billion dollar market potential.

Job Description:
You will own the backend architecture for a sophisticated SaaS platform that processes hundreds of millions of rows of cloud billing data. Navigating complex OLTP and OLAP systems like PostgreSQL and ClickHouse, you will build sub-second APIs that help Fortune 500 enterprises manage millions in infrastructure spend with total precision and clarity.

Location:
San Francisco, USA

Why this role is remarkable:
- Work at the ground floor of a startup with a massive "unfair advantage"—an existing community of 35,000 subscribers and deep Fortune 100 relationships.

What you will do:
- Design and operate robust backend services using Python and Flask that serve as the backbone for the flagship Skyway cloud financial platform.
- Build and maintain high-performance APIs and data validation patterns that enable frontend and data engineers to deliver low-latency product experiences.
- Optimize complex data workflows across PostgreSQL and ClickHouse to ensure financial correctness and observability for clients making million-dollar decisions.

Job Title:
Senior Backend Engineer

Salary:
Not Disclosed

Company Description:
London-based startup building the world's first autonomous technology deployment platform for heavy industries.

Job Description:
You will build the orchestration layer automating software roll-outs for global infrastructure projects. This role involves designing DAG-based workflows, typed action contracts, and reliable async systems. Working at the ground level, you'll create the "paved roads" for a platform that replaces manual consultancy with AI-driven deployment and deep enterprise integrations.

Location:
London, UK

Why this role is remarkable:
- Build a first-of-its-kind orchestration engine that manages complex deployments for the world's largest engineering and construction enterprises.

What you will do:
- Design and maintain the backend platform using Python and FastAPI to power autonomous deployment workflows.
- Own the end-to-end reliability of the system, including CI/CD pipelines, async worker health, and pragmatic observability.
- Collaborate directly with the CTO to translate product requirements into scalable, production-grade systems with clear API contracts.

The ideal candidate:
- Strong experience shipping production-grade backend systems in Python with a focus on clear API design and system reliability.
- Proven ability to manage production operations, including deployments, incident response, and building robust observability dashboards.
- High engineering judgment with a bias for simple, shipping solutions over over-engineered architectures in an ambiguous startup environment.
