Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone’s reach while doing the most important work of your career.

About the team

The Developer Productivity organization works to make the most productive place of an engineer’s career. The Code Review team builds the tools and processes that help engineers review and ship code safely and efficiently. We treat engineers’ attention as a valuable resource, building tools that help them understand changes and focus on the decisions that need human judgment.

Our goal is to build an AI review agent that outperforms human review at preventing problems after changes merge, while helping developers move quickly. We are also moving code review from GitHub to Orbit Diffs, ’s own review interface, and enabling ’s migration from legacy source control infrastructure to new systems, including infrastructure built at .

What you’ll do

As a Staff Software Engineer, you will take ownership of problems across the code review domain, set technical direction, and build alignment across . You will combine technical leadership with hands-on engineering to build the systems that determine which changes can be approved by agents and when human judgment is needed. Your decisions will influence both the pace and safety of changes across .

You will work across user interfaces, backend services, source control integrations, and agent harnesses. Our team works primarily in Go, Ruby, and TypeScript, and you will use the technologies each problem requires. As AI capabilities evolve, you will experiment with new approaches and turn them into reliable, maintainable tools for developers.

Responsibilities

• Set technical direction for code review, build alignment across , and mentor engineers as you lead complex projects from problem definition through delivery and adoption
• Build and improve agent harnesses that enable review agents to exercise judgment and safely approve pull requests
• Develop evaluations that compare agent and human review decisions, assess the safety of merged changes and the impact on developer velocity, and guide improvements to approval decisions
• Evaluate and apply advances in AI and agent orchestration to accelerate engineering delivery across while maintaining review quality, maintainability, reliability, and change safety
• Build and maintain Orbit Diffs and the surrounding code review tools, helping engineers understand changes and focus their attention where their judgment is most valuable
• Improve code ownership, intelligent reviewer assignment, stacked pull request workflows, and controls for change management
• Support ’s migration to new source control infrastructure by adapting code review workflows and integrations
• Partner with security, compliance, infrastructure, reliability, and language and runtime teams to improve how software changes are evaluated and approved across
