Founding Full-Stack Engineer
$160,000–$220,000 year
On-siteSan Francisco, California, United States
Job Summary
Own end-to-end product engineering for backend, frontend, and infrastructure, including AI-driven features like context engineering and internal GenAI tooling. Deliver telemetry, observability, and system intelligence while iterating rapidly under incomplete information. Switch frequently between products, systems, and customer realities, maintaining direct interaction with founders and early users. This founding seat at an early-stage AI company requires shipping fast with a strong backend bias in TypeScript, Node, and Next.js. You will actively use AI tools in your daily workflow and thrive in a high-trust, high-expectation culture where priorities shift weekly. Best case: help define a category and build systems that scale with AI.
Required Qualifications
- 5+ years building and shipping real products as a full-stack engineer
- Strong backend bias (60/40 backend/frontend)
- Production experience with TypeScript, Node, Next.js
- Startup experience where priorities changed weekly — and you still shipped
- You actively use AI tools in your daily workflow (not interested in learning)
- Clear, concise communicator — in writing and conversation
- Seed to Series A startup experience
- Experience with developer tooling, telemetry, or infra-adjacent systems
- Public technical thinking (blog, GitHub, X, talks)
- Evidence of learning velocity over pedigree
