<p><strong>Job Title</strong></p>

<p>AI Engineer</p>

<p><strong>Salary</strong></p>

<p>£85k+ + Equity</p>

<p><strong>Company Description</strong></p>

<p>Tier 1 VC-backed AI consultancy founded by exited TikTok and HR-tech founders</p>

<p><strong>Job Description</strong></p>

<p>You will bridge the gap between frontier AI and traditional industries by deploying production systems for private equity funds, manufacturers, and logistics firms. 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.</p>

<p><strong>Location</strong></p>

<p>London, UK</p>

<p><strong>Why this role is remarkable</strong></p>

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

<p><strong>What you will do</strong></p>

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

<p><strong>The ideal candidate</strong></p>

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

<p><strong>Who are Jack &amp; Jill?</strong></p>

<p>Ok, I&#39;ll go first. I&#39;m Jack, an AI that gets to know you on a quick call, learning what you&#39;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.</p>

<p>And I&#39;m Jill, an AI Recruiter who talks to companies to understand who they&#39;re looking to hire. Then I recruit from Jack&#39;s network, making an introduction when I spot an excellent candidate.</p>

<p><strong>Job Description</strong></p>

<p>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.

<p>San Francisco, USA</p>

<p><strong>Why this role is remarkable</strong></p>

<ul>
  <li>Chart the map for the &quot;pre-construction&quot; category, a massive $13 trillion market that still relies on spreadsheets and manual document review.</li>

<p>Founding Engineer - Backend &amp; Data Platform</p>

<p><strong>Salary</strong></p>

<p>$175,000 - $225,000 + Equity</p>

<p><strong>Company Description</strong></p>

<p>Fintech startup automating mortgage lending for self-employed borrowers, backed by industry leaders and trusted by Goldman Sachs, JPMorgan, and Morgan Stanley.</p>

<p><strong>Job Description</strong></p>

<p>As the founding backend and data platform engineer, you will architect the infrastructure that powers non-traditional mortgage lending. You&#39;ll own the end-to-end data lifecycle—from ingesting banking and tax data via Plaid and Finicity to building canonical models and ML-ready pipelines. This high-agency role involves shaping the core product used by major global financial aggregators.</p>

<p><strong>Location</strong></p>

<p>San Francisco, Austin, NYC, Remote</p>

<p><strong>Why this role is remarkable</strong></p>

<ul>
  <li>Significant architectural influence as a founding team member, building greenfield infrastructure for a product already trusted by Goldman Sachs, JPM, and Morgan Stanley.</li>
  <li>High-agency environment led by a team from Airtable and Opendoor, operating with a flat structure where engineers participate in the entire product lifecycle.</li>
  <li>Aggressive equity upside in a fintech solving a massive market gap for 76 million self-employed Americans who are currently underserved by traditional lenders.</li>
</ul>

<p><strong>What you will do</strong></p>

<ul>
  <li>Design and operate resilient data ingestion and normalization pipelines for complex financial sources including banking, tax transcripts, and accounting platforms.</li>
  <li>Build core platform infrastructure including authentication, webhooks, rate limiting, and vendor-agnostic abstraction layers to ensure system reliability and scalability.</li>
  <li>Develop in-house feature extraction pipelines and productionize ML models for income categorization, anomaly detection, and automated financial insights.</li>
</ul>

<p><strong>The ideal candidate</strong></p>

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

<p><strong>Job Description</strong></p>

<p>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.

<ul>
  <li>Work on a mission-critical platform used by 50+ regulated companies including Beckman Coulter and Paradromics to save lives through faster therapy development.</li>
  <li>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.</li>

  <li>You have a proven track record of shipping complex projects and possess strong systems-design instincts regardless of your specific tech stack.</li>
  <li>You thrive in high-standard, in-person environments and are a self-directed, first-principles thinker who values impact over bureaucratic process.</li>

<p><strong>Job Title</strong></p>

<p>Founding AI Engineer — Agent Runtime</p>

<p><strong>Salary</strong></p>

<p>$100,000 – $150,000 + Equity</p>

<p><strong>Company Description</strong></p>

<p>$3.5M-funded San Francisco AI startup founded by serial entrepreneurs from LeanData and Chronicled</p>

<p><strong>Job Description</strong></p>

<p>As the first engineering hire, you will build a policy-driven runtime that executes high-stakes B2B commercial workflows. Unlike simple LLM wrappers, you&#39;ll architect a deterministic execution layer where models negotiate real contracts and protect revenue. Reporting to a veteran CTO, you&#39;ll own the agent pipeline, state management, and safety guardrails.</p>

<p><strong>Location</strong></p>

<p>San Francisco, USA</p>

<p><strong>Why this role is remarkable</strong></p>

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

<p><strong>What you will do</strong></p>

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

<p><strong>The ideal candidate</strong></p>

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

<p><strong>Who are Jack &amp; Jill?</strong></p>

<ul>
  <li>Lead technical direction and product strategy for core features, translating ambiguous user needs into high-impact shipping decisions without PMs.</li>
  <li>Build and optimize production AI systems using fine-tuned open-source models, retrieval-augmented generation (RAG), and advanced tool-use architectures.</li>
  <li>Own features end-to-end, from conducting qualitative user research to deploying scalable infrastructure that handles millions of automated email drafts.</li>
</ul>

<p><strong>The ideal candidate</strong></p>

<ul>
  <li>At least 5 years of experience shipping production software with deep expertise in Python or TypeScript and a history of extreme ownership.</li>

<p>Series A AI context infrastructure startup founded by ex-Visa and LinkedIn data veterans</p>

<p><strong>Job Description</strong></p>

<p>You will build the semantic layer essential for the next generation of autonomous enterprise agents.

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

<p><strong>What you will do</strong></p>

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

<p><strong>The ideal candidate</strong></p>

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