About The Position

This role involves training large language models (LLMs) to generate production-grade code across various programming languages. Key tasks include comparing and ranking code snippets, explaining their merits, and repairing/refactoring AI-generated code for correctness, efficiency, and style. The position also requires injecting feedback (ratings, edits, test results) into the Reinforcement Learning from Human Feedback (RLHF) pipeline to ensure its smooth operation. The ultimate goal is to teach the model to propose, critique, and improve code in a manner similar to an expert engineer. This is an independent contractor role, open to applicants in accepted locations only, and is not compatible with visa statuses requiring W-2 employment or employer sponsorship.

Requirements

• 3+ years of professional software engineering experience in C++
• Strong code-review instincts — you can spot logic errors, performance traps, and security issues quickly
• Extreme attention to detail and excellent written communication skills
• Comfortable reading documentation and language specs, and able to work well in an asynchronous, low-oversight environment
• Identity verification: Applicants will be required to verify their identity and confirm they have valid documentation to work as an independent contractor in their country of residence

Nice To Haves

• Constraint programming experience
