Founding Engineer - Agentic AI

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

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.
