About the Opportunity
This opportunity is for experienced AI Engineers and Software Engineers with expertise in Python, Java, C++, Rust, TypeScript, algorithms, debugging, codebase refactoring, and performance optimization to contribute to advanced AI research and evaluation projects.
You'll apply your software engineering expertise to create Reinforcement Learning (RL) environments that test AI models on complex software engineering workflows. Tasks may involve debugging, feature implementation, code refactoring, performance optimization, and working with Model Context Protocol (MCP) tools.
No prior AI experience is required — your technical expertise is what matters.
Responsibilities
Design and develop Reinforcement Learning environments that evaluate AI models on realistic software engineering workflows.
Create tasks involving bug fixing, feature implementation, codebase refactoring, and performance optimization.




Develop reproducible environments with deterministic verification and golden reference solutions.
Design workflows that require AI agents to discover and reason over information using MCP tools and real MCP servers.
Evaluate AI-generated software solutions for correctness, maintainability, performance, and scalability.
Apply strong knowledge of algorithms, data structures, debugging, and systems engineering to create challenging evaluation tasks.
Provide structured technical feedback to improve AI model reasoning and software engineering capabilities.
Collaborate with technical teams to maintain consistent evaluation standards and high-quality deliverables.
Required Qualifications
Strong proficiency in at least one of C++, Python, Java, Go, TypeScript, or Rust.
Deep understanding of algorithms, data structures, and performance optimization.
Demonstrated experience debugging complex software issues and delivering maintainable solutions.
