Requirements
- 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
- Prior experience at developer-centric companies (Bonus)
- Hands-on experience designing or maintaining agent SDKs or other agentic developer tooling (Bonus)
- Existing user of OpenRouter, contributions to open-source projects, or side projects in the AI tooling space (Bonus)
Responsibilities
- 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
