About the role

Key responsibilities & impact

Help train large language models (LLMs) to write production-grade code across a wide range of programming languages:
Compare and rank multiple code snippets, explaining which is best and why
Repair and refactor AI-generated code for correctness, efficiency, and style
Inject feedback (ratings, edits, test results) into the RLHF pipeline and keep it running smoothly

Requirements

What you’ll need

3+ years of professional software engineering experience in C++ (constraint programming experience is a bonus, but not required)
Strong code-review instincts — you can spot logic errors, performance traps, and security issues quickly
Extreme attention to detail and excellent written communication skills. Much of this role involves explaining **why** one approach is better than another. This cannot be overstated.
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.
