We are hiring experienced software engineers to design long-horizon coding tasks: realistic, investigation-heavy engineering problems drawn from substantial codebases, used to evaluate and train advanced AI coding agents. The ideal candidate is comfortable working across large multi-file codebases, reasoning about how a bug or feature ripples across modules, and building reproducible, containerized environments backed by rigorous tests. You should be able to author a problem a strong engineer would recognize as real work, and a verifier that grades a solution the way a careful reviewer would. Experience with Docker and containerized workflows is required. You will also need a substantial private codebase of your own to author tasks against.
