Senior Product Engineer

What we're looking for:

We need someone with 5+ years of experience who has owned products end-to-end, from ideation through launch, in a startup or high-growth environment. You should be comfortable building 0-to-1 products in ambiguous spaces and have a track record of shipping developer tools or engineer-facing products that set a high bar for user experience. Bonus points if you've worked in developer tooling, AI-powered products, or have experience building coding agents or CI/CD platforms.

What you'll do:

- Own entire product surfaces end-to-end — from early ideation and systems design through to shipping and iterating with customers

- Build and evolve next-generation developer tools (including Codesmith, our background coding agent) — designing workflows, UI, and infrastructure that let engineers delegate coding tasks to AI

- Work closely with founders to formulate product ideas, validate them, and bring them to market in days, not months

- Make critical architectural and systems design decisions across the full stack that will define products for their lifetime

- Prototype and iterate rapidly on AI-powered features — from natural language interfaces to automated fix generation — owning everything from prompt design to backend service to UI

- Ship polished, high-performance product surfaces across analytics, observability, and agent platforms where engineers interact daily
