This role is open to contractors in accepted locations only. For US applicants, this is a 1099 independent contractor role, not compatible with F-1 OPT, STEM OPT, or any visa status that requires W-2 employment, guaranteed hours, or employer sponsorship. The position involves training large language models (LLMs) to write production-grade code across various programming languages. This includes comparing and ranking code snippets, repairing and refactoring AI-generated code, and injecting feedback into the RLHF pipeline to improve the model's code generation capabilities. The role is fully remote, with compensation ranging from $30–$70/hr based on location and seniority, and requires a minimum of 15 hours per week, with up to 40+ hours available, though hours are project-dependent and not guaranteed.
