Job Description Job Description List of accepted countries and locations 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. Tech Stack We are looking for Fullstack JavaScript or TypeScript engineers • React, Next.js • Node • Postgress Logistics • Location: Fully remote (work from anywhere). • Hours: Minimum 15 hrs/week with the ability to work up to 40 hours per week • Engagement: 1099 contract Straightforward impact, zero fluff.
