For US applicants

This is a 1099 independent contractor role. It is not compatible with F-1 OPT, STEM OPT, or any visa status that requires W-2 employment, guaranteed hours, or employer sponsorship.

We are unable to provide offer letters or employment verification for this role.

What You'll Be DoingHelp 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.

RLHF in one line: Generate code expert engineers rank, edit, and justify convert that feedback into reward signals reinforcement learning tunes the model toward code you'd actually ship.

What You'll Need

• 3+ years of professional software engineering experience in Java (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.

What You Don't Need

• No prior RLHF or AI training experience
