Role Title: Software Engineer - Backend

Role Type : Contractor (~15 hrs a week)

Location: Remote

You’ll create Reinforcement Learning Environments that test a model’s ability to solve real software engineering problems: tracking down subtle bugs, building non-trivial features, refactoring, and optimizing performance. Each task means defining the problem, building a reproducible environment, and writing a reference solution.

Scope of Work

Create realistic, challenging coding tasks for frontier AI models, drawn from repositories you know well.

Design problems that require real engineering skill — subtle bugs, non-trivial features, meaningful performance work — not lookup or boilerplate.

Build a reproducible environment for each task.

Write deterministic verifiers...
