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 Kingdom
Overview:
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.
Responsibilities:
Drive and execute technical roadmap that aligns with product goals, ensuring that engineering efforts are strategically prioritized and incorporating the adoption of new technologies and methodologies where applicable.
Work with organizational leaders to shape GitHub’s AI product portfolio, identifying opportunities for innovation and leading initiatives that scale globally.
Drive employee growth and development, manage performance, and ensure the engineering team's skills remain current by staying abreast of industry developments and best practices.
Own incident response and reliability practices, ensuring live services meet SLOs and postmortems drive systemic improvements. Oversee capacity planning to ensure performance, reliability, and compliance.
Champion experimentation and telemetry-driven development, enabling rapid iteration and data-informed decisions.
Identify novel bottlenecks in AI-powered development workflows to improve team and organizational impact.
Drive engineering excellence through automation, tooling, and standardization across deployment, testing, and operations. Facilitate cross-team communications, identify dependencies, and resolve conflicts to ensure seamless integration and support across products, applications, and services.
Partner with stakeholders such as product managers and technical leads to determine requirements for services or complex scenarios, leveraging feedback channels to incorporate insights into future designs.
