Founding Engineer at Appnigma AI
Appnigma AI is seeking a Founding Engineer (Platform) to build the infrastructure powering AI-driven Salesforce and HubSpot managed packages. This isn't a role for specialists; we need a "founder-mode" operator who can navigate Terraform, distributed systems, and production LLM agents with equal mastery. You'll own critical workstreams like tenant isolation and agent runtimes, working as a technical peer in an early, small, founder-led team. If you've personally debugged race conditions in queue workers and shipped multi-tenant SaaS at scale, this is your chance to shape a platform from the ground up.

Role overview
CRM integration Infrastructure
What you will do
- Architect and maintain robust AWS infrastructure using Terraform, managing ECS Fargate, RDS, Secrets Manager, and KMS to ensure total tenant isolation.
- Develop and optimize the LLM agent runtime, implementing tool-use loops and sandboxed execution environments to power intelligent Salesforce and HubSpot integrations.
- Lead end-to-end feature delivery, spanning from complex backend OAuth2/webhook integrations to shipping frontend React features that enable a seamless developer experience.
Who this is a fit for
- At least 5 years of production TypeScript/Node experience in distributed systems, with deep knowledge of idempotency, retries, and comparing queue workers like pg-boss versus SQS.
- Proven expertise in multi-tenant SaaS security, specifically managing secret isolation and encryption-at-rest in environments where cross-tenant data leaks are a zero-tolerance risk.
- Fluent in AWS and Terraform with a "founder-mode" mindset, capable of turning high-level plans into production code independently while writing concise, decision-shaped design documentation.
Why this role is remarkable
- True founding influence: Work as a technical peer to the founders, owning major workstreams like self-serve shared infrastructure and encryption-at-rest design without needing a second opinion.
- Cutting-edge AI at scale: Ship production LLM agents using tool-use loops and sandboxed execution, moving beyond simple RAG demos into real agentic workflows using the Claude Agent SDK.
- High-stakes engineering: Tackle complex multi-tenant isolation and security challenges where protecting secrets between ISV tenants is a core engineering concern, not a hypothetical.
