 * Depth in Go, Ruby, TypeScript, or Python, with the operational experience of running a distributed service on call at GitHub scale.
 * Experience building an LLM-backed or agentic product in production or partnering with research teams to ship model capability.

## Description

* Drive how the review agent works: the context it reasons over, the models it runs, and what it carries across reviews.
 * Bet on where model capability is heading, and work with model labs and research teams to turn it into better reviews.
 * Define what a great AI review is, and hold the product to it with offline evals, online experiments, and production evidence.
 * Own the quality of the end-to-end review experience across VS Code, the GitHub Copilot app, and the GitHub Copilot CLI, and pull requests.
 * Own the reliability of a high-throughput service running at GitHub scale, including the on-call rotation.
 * Mentor senior and staff engineers, collaborate across disciplines, and help steer the team and product, all while staying hands-on: experimenting, shipping code, and building evals.
 * Work at the frontier of how software gets built with agents and evolve workflows that make the whole team faster.
