The opportunity
About the Team The Agent Post-Training team creates the frontier agents OpenAI ships to the world. We are training the models behind our agents in Codex, ChatGPT, the API, and other frontier products: persistent, proactive intelligence that can operate computers, collaborate…
What they're looking for
- Help decide which agentic capabilities, behavioral fixes, and partner-team: integrations are ready for inclusion in major model runs.
- Debug hard failures in shipped or near-shipped models by moving between: traces, evals, training data, model outputs, and product context.
- Work on early-training and alignment interventions, including data mixtures,: objectives, synthetic data, and eval loops that shape downstream agent behavior.
- Improve the machinery for large-scale training and launch: experiment velocity, reliability, observability, reproducibility, cost, latency, and production readiness.
