Staff Software Engineer

About GitHub: GitHub is the world’s leading platform for agentic software development — powered by Copilot to build, scale, and deliver secure software. Over 180 million developers, including more than 90% of the Fortune 100 companies, use GitHub to collaborate, and more than 77,000 organisations have adopted GitHub Copilot. Locations: In this role you can work from Remote, United States Overview: As a Staff Software Engineer on the Code and Review team, you will shape the pull request and code review experience used by over 100 million developers. Pull requests are the beating heart of collaboration on GitHub — where ideas become code, feedback drives quality, and teams ship with confidence. You will design, build, and evolve the systems behind pull request creation, code review, the Files Changed experience, and the automation and integration workflows that power modern development. We’re looking for engineers who combine deep technical skill with product empathy — people who care about craft and understand that great developer tools reflect the teams that build them. Agent\-driven software development is changing how code is written, reviewed, and shipped. As AI agents become first\-class participants in the development lifecycle, the pull request experience must evolve to support new collaboration patterns between humans and machines. You’ll help define what that future looks like. This is a fully remote role. Our distributed team values async communication, deep work, and trust\-based collaboration. Responsibilities: * Design, develop, test and ship high\-quality solutions that scale across GitHub’s services, with a focus on the pull request and code review workflow. Take pride in writing maintainable code and becoming deeply familiar with the systems you build. * Provide technical leadership, mentorship, and code reviews that elevate the team; support others in producing extensible, maintainable code that integrates cleanly with downstream dependencies. * Own the health and quality of the systems the team builds, including participating in on\-call rotations and live incident response. * Contribute across the full pull request product surface — PR creation, code review, merge workflows, and the Files Changed experience — owning features end\-to\-end from design through delivery. * Help evolve the code review and merge experience to support agent\-driven development, where AI\-authored code must be reviewed, validated, and shipped with the same rigor as human\-authored contributions. * Write architecture briefs and proposals; carry out code experiments to validate approaches for improving the pull request experience. * Collaborate with product, design, and platform engineering to lead technical discussions, including design trade\-offs and cost considerations. * Guide teams in developing testing strategies, defining success metrics, and integrating customer feedback — while ensuring architecture meets security and compliance s
