Principal Software Engineering Manager

GitHub is shaping the future of software development in the age of AI agents — and search is at the heart of it. As GitHub's lexical and semantic code search engine, Blackbird powers context retrieval for business-critical experiences across the platform and our Copilot products, including Cloud Agent, Code Review, Copilot CLI, and VS Code. 

We're looking for a Principal Engineering Manager to lead the development of Blackbird. You'll be part of our Copilot Agents organization, positively impacting millions of software developers and AI agents around the world who are building everything from open source to global enterprises.  

We are looking for creative problem solvers and diverse thinkers, people who care about culture as well as customers and features. We believe that how we do things is as important as what we do. Big vision, a common purpose, passion for quality, curiosity, dedication, and investment in fun and collaboration are what lead to great results. Great products reflect the teams that build them.  

More of the world’s development data lives on GitHub than anywhere else. Helping developers navigate and understand that data is a core part of GitHub’s mission, and an area with significant potential we have only begun to realize. We have high aspirations for how we can help developers understand and navigate code, and for making collaboration more seamless. The foundation for these efforts is our purpose-built code search engine which powers lexical and semantic code search in GitHub’s core search experience as well as GitHub’s Copilot products. 

The ideal candidate has strategic vision, technical leadership in distributed systems and generative AI application architectures, as well as the ability to mentor very senior engineers, build empowered high-trust teams, and foster a culture of technical excellence, operational rigor, and experimentation. You will manage a team of staff and principal engineers and work closely with partner teams across the Copilot Agents organization.
