About The Position

Create Reinforcement Learning Environments that test AI models’ ability to solve real software engineering problems, including tracking down subtle bugs, building non-trivial features, refactoring, and optimizing performance. Work involves defining each problem, building a reproducible environment, and writing a reference solution. The project is remote, project-based, and paid per approved task, with an expected commitment of approximately 15 hours per week. Selected experts are expected to begin their first tasks within 24–48 hours after completing onboarding.

Requirements

• Hands-on expertise in at least one of Python, Java, Rust, Go, C++, or TypeScript.
• Deep understanding of algorithms, data structures, and software engineering principles.
• Proven ability to debug complex systems, resolve bugs, and deliver effective optimizations.
• Experience with large codebase refactoring and legacy system modernization.
• Track record of delivering high-impact features from conception through delivery.
• Strong documentation and communication skills to explain technical concepts clearly.

Nice To Haves

• Interest in AI and its technical challenges; previous AI experience is not required.

Responsibilities

• Create realistic, challenging coding tasks for frontier AI models using repositories you know well.
• Design problems requiring real engineering skills, such as resolving subtle bugs, implementing non-trivial features, or improving performance.
• Build a reproducible environment for each task.
• Write deterministic verifiers that accept correct solutions across different valid implementations and reject incorrect, incomplete, or hard-coded approaches.
• Provide a reference solution for each task.
• Flag tasks that are ambiguous or unverifiable rather than submitting them.
