Founding Engineer - Agentic AI (Full-stack)
What you'll do
- Design, build, and ship features end to end — front end, back end, and everything in between.
- Build LLM-powered agents and workflows, and take them from prototype to production.
- Turn experiments into reliable, maintainable systems.
- Work with the founders and customers to decide what to build next.
- Help set how we build: code review, testing, and release practices.
- Keep up with a fast-moving field, try new models and tools, and adopt what actually works.
What we're looking for
- 2+ years shipping production software, or equivalent proof of work. We care more about what you've built than where.
- Strong in TypeScript, and comfortable across the stack, UI, APIs, databases.
- Cloudflare developer platform Workers, D1, R2, Durable Objects, Workflows. You've deployed real apps on it.
- Hands-on experience building with LLMs prompting, tool calling, structured outputs.
- Ownership. You take a problem from vague to done without waiting to be told how.
- Comfort with ambiguity. Priorities change; you adapt without losing quality.
Nice to have
- Experience with agent frameworks or SDKs
- MCP, RAG, and vector databases
- Evals and LLM observability
- Cloudflare AI tooling — Workers AI, AI Gateway, the Agents SDK, Vectorize
- Early-stage startup or founding-team experience
- Open-source work or side projects you can show us
What we offer
- Real ownership from day one
- A small, fast team with no layers between you and the decisions
Not for you if
- You need a spec for every ticket.
- You want to own one narrow piece forever.
- You measure yourself in lines of code.
- You think an agent demo is a product.
