Software Engineer, AI (Ruby)
About The Position
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. 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 Ruby (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.
