Principal Software Engineering Manager

About the role

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 are seeking a Principal Engineering Manager to lead the development of Blackbird.

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.
