The AI Software Engineer (Ruby) at G2i Inc. will help train large-language models (LLMs) to write production-grade code by evaluating, ranking, and refining AI-generated code snippets. This remote role focuses on providing expert human feedback that shapes model behavior through reinforcement learning with human feedback (RLHF).
What You'll Do
- 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
- Enable the model to learn to propose, critique, and improve code through expert human evaluation
What We're Looking For
- 3+ years of professional software engineering experience in Ruby
- 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
- You thrive in an asynchronous, low-oversight environment
