Own and evolve our public REST API and the developer experience around it — from API design and ergonomics to versioning, errors, and rate-limiting behavior.
Build and maintain our client SDKs across TypeScript and Python, and lead the launches of our upcoming SDKs.
Ship our Agent SDK, expanding it into a surface for multi-step, agentic workloads built on OpenRouter.
Treat documentation, examples, and starter repos as products — instrument what developers and AI coding agents land on first, and make sure those are strong entry points to OpenRouter.
Make every developer-facing surface agent-friendly, given that AI coding agents are users of our APIs and SDKs.
Collaborate with our DevRel, Product, and Platform teams to identify gaps in the developer ecosystem and run with them end to end.

5+ years building external-facing developer products — APIs, SDKs, or developer platforms widely used by engineers.
Strong API and SDK design instincts; you've shipped libraries that developers integrate with and you have opinions about what makes them good.
Strong TypeScript skills; we're a TypeScript shop and TypeScript is widely used across the AI ecosystem.
AI-forward in your own workflow and interested in what agentic systems can do.
High agency and a bias toward action — you spot something missing in the developer ecosystem and ship it without waiting for a ticket.
Comfortable owning a product line at a small company where boundaries between teams are fluid.
Strong written communication; docs, changelogs, and SDK reference material are part of the job.
Pragmatic about tradeoffs between speed and simplicity.
