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
End result: the model learns to propose, critique, and improve code the way you do.

Requirements

3+ years of professional software engineering experience in Rust
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.
