API Engineer

As a small team, they’re all generalists and constantly picking up new challenges. Regarding systems and infrastructure, they’re looking to work with experienced engineers who can dive deep into design and performance problems, architect robust backend services, and build foundational APIs that scale. This shift demands a new generation of APIs: ones that are reliable, permission-aware, and deeply composable. As an API engineer, you won’t just be building for human developers—you’ll be shaping the interface through which AI agents understand and operate within Linear. This is foundational work, with the opportunity to help define an emerging interaction model. The tech stack is built with TypeScript, Node.js, GraphQL, and PostgreSQL.
