AI Software Engineer (Ruby)

Software Engineer, AI — Code Evaluation & Training (Remote) List of accepted countries and locations 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. What You’ll Need • 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. • You enjoy reading documentation and language specs and thrive in an asynchronous, low-oversight environment. What You Don’t Need • 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. Tech Stack We are looking for engineers with a strong command of Ruby.
