Full Stack Engineer

About the role

As a Full Stack Engineer, you build AI-enabled products end to end. You own features across the whole stack, from the database to the backend to the interface people use, and bring in LLMs where they genuinely help. We work in TypeScript and ship fast on Vercel, Railway, and Supabase.

You work the way we build: agents at scale, humans accountable. You pair with coding agents on every story, setting the approach, reviewing the diff, and owning what ships. It's a great fit for a product-minded engineer who moves quickly, cares about the details users notice, and measures success by what reaches production.

What you'll do

• Build AI-enabled features across the full stack: data models and queries, backend services and APIs, and the React / Next.js interface people use.
• Wire LLMs into the product where they add real value (agentic features, automation, structured generation), with evals that prove the behavior holds.
• Ship on a modern stack: frontends on Vercel, services on Railway, data, auth, and storage on Supabase.
• Pair with coding agents on each story. Set the approach, review the diff, stay accountable for what merges.
• Own quality end to end: types, tests, error and empty states, performance, the edge cases users actually hit.
• Turn a rough idea or product brief into working software quickly, iterating with the team in tight feedback loops.
• Keep what you ship healthy in production with observability, logging, and fast follow-ups.

What you'll bring

• 3+ years building and shipping full-stack web applications in production.
• Strong TypeScript across the stack, with React / Next.js on the front end and Node on the back.
• Hands-on experience putting LLMs into products: calling model APIs, prompt and context engineering, handling streaming, structured output, and failure modes.
• Comfort on a modern deploy stack: Vercel, Railway, and Supabase (Postgres, auth, storage).
• Real product sense. You care how a feature behaves and feels, not just whether it works.
• You default to shipping. You can take a feature from idea to production without hand-holding, and own the result.
• Clear communication and comfort with fast-moving priorities.

Bonus points

• Experience with agentic coding tools (Claude Code, Codex, Cursor).
• Built evals or guardrails for LLM features.
• Comfort with background jobs, queues, or realtime (Supabase Realtime, websockets).
• An eye for design, or a track record of working closely with designers.
• Exposure to financial services or healthcare.
