OpenAI's Codex team, which builds agentic software-engineering tools, seeks a data scientist to measure product-market fit for AI developer tools. The work covers defining developer-productivity metrics — suggestion acceptance, edit distance, compile and test pass rates, latency — designing A/B tests and staged rollouts, building dashboards that break results down by language, framework, repository size and task type, and diagnosing failure modes with Research. The posting asks for five or more years in a quantitative role, SQL and Python, experiment design and causal inference; coding-model or LLM familiarity helps.
