Train frontier models to reliably operate computers, from data pipelines through major model runs
A research role on OpenAI's Agent Post-Training team focused specifically on computer use: designing experiments, building evals/environments/graders, and driving RL and data-pipeline improvements that shape agentic behavior shipped into Codex, ChatGPT, and the API. The role expects hands-on experience with LLMs, RL/RLHF/RLAIF, evals, and production ML systems, plus comfort operating in open-ended, noisy-signal research territory across research, product, infra, and safety boundaries.

常见提问方向
Walk me through a post-training or RL experiment you ran on an agentic/tool-using model
How would you build an eval or grader to catch a specific class of computer-use failure
Describe debugging a hard, messy model failure and turning it into a concrete fix
How do you decide whether a model improvement is ready to go into a major training run
How do you balance research exploration against the need for reliable, production-ready agent behavior
