Full Stack AI Engineer

About the role

We are looking for a Full Stack AI Engineer for a start‑up client based out of San Francisco, CA, USA. This is a remote contract engagement with an availability of 40 hours per week and at least 4 hours of overlap with US PST working hours for regular syncs. The engineer should work independently and discuss progress every one to two days.

Key responsibilities

• Build product features end‑to‑end across the backend and frontend.
• Develop Python APIs, data workflows, and document‑processing systems.
• Build and refine the user interface using TypeScript, React, and Next.js.
• Create LLM and agentic workflows involving structured outputs, retrieval, tool use, evaluations, and observability.
• Use AI coding tools such as Claude Code, Codex, and ChatGPT while reviewing and taking responsibility for the resulting code.
• Handle deployment, debugging, testing, and basic application monitoring.
• Maintain clear technical documentation and keep the codebase understandable and maintainable.
• Work independently, communicate progress clearly, and raise blockers early.

Required profile

• Typically 3‑6 years of software engineering experience, though demonstrated ability matters more than a specific number of years.
• Strong Python backend development.
• Working experience with TypeScript and React; Next.js experience is preferred.
• Experience building APIs, working with databases, and shipping complete product features.
• Practical experience building production LLM‑powered applications or agentic workflows, beyond basic chatbot prototypes.
• Evidence of personally taking features from requirements through implementation, testing, and deployment.
• Comfortable working in an early‑stage environment with changing requirements, ambiguity, and substantial responsibility and autonomy.
