About The Position

Software Engineer, AI — Code Evaluation & Training (Remote)
Important for US applicants: This is a 1099 independent contractor role and is not compatible with F-1 OPT, STEM OPT, or other visa statuses that require W-2 employment, guaranteed hours, or employer sponsorship. We are unable to provide offer letters or employment verification for this role.
Help train large-language models (LLMs) to write production-grade code across a wide range of programming languages:
Compare & rank multiple code snippets, explaining which is best and why.
Repair & 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.

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.
• Much of this role involves explaining why one approach is better than another. This cannot be overstated.
• You enjoy reading documentation and language specs and thrive in an asynchronous, low-oversight environment.
• We are looking for engineers with a strong command of JavaScript.

Nice To Haves

• Constraint programming experience is a bonus, but not required
• No prior RLHF (Reinforcement Learning with Human Feedback) or AI training experience.
• No deep machine learning knowledge. If you can review and critique code clearly, we’ll teach you the rest.

Responsibilities

• Compare & rank multiple code snippets, explaining which is best and why.
• Repair & refactor AI-generated code for correctness, efficiency, and style.
• Inject feedback (ratings, edits, test results) into the RLHF pipeline and keep it running smoothly.
