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 that accept correct solutions across different valid implementations, while rejecting incorrect, incomplete, or hard-coded approaches.

• Provide a reference solution showing how the task can be solved.

• Flag tasks that turn out to be ambiguous or unverifiable rather than submitting them.

Preferred Qualifications

• Significant hands-on expertise in at least one of: Python3, 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 communicat
