Job description

Software Engineer, AI

Train large-language models (LLMs) to write production-grade code:

• 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.

What is Needed

• 4+ years of professional software-engineering experience.

• Extreme attention to detail and excellent writing skills—most of the job is explaining why one solution is better than another. This requirement cannot be overstated!

• You actually enjoy reading documentation and specs.

• Proven ability to thrive in a fully asynchronous, low-oversight remote environment.

• Strong code-review instincts: can spot logic errors, performance traps, and security issues quickly.

What is Not Needed

• No prior RLHF or AI-training experience required.

• You don’t need deep machine-learning knowledge—if you can review code and explain your reasoning, we’ll teach you the RLHF bits.
