Overview:
Do you want to make software development a delight for the entire world? Join us at GitHub! We want you to help build and deliver the best end to end software development experience across GitHub.
We’re looking for a Staff Software Engineer to join the GitHub Enterprise Server team. GHES is a self-hosted version of GitHub that provides all the features and functionality of GitHub.com but allows organizations to host it on their own infrastructure. Our customers run GHES in some of the most demanding enterprise environments in the world at scales with tens of thousands of developers, millions of repositories, and mission-critical workloads.
In this role, you’ll lead the performance testing and analysis strategy for our enterprise offerings: building frameworks, designing workloads that mirror real customer usage, diagnosing bottlenecks across the stack, and working cross-functionally to ensure every release scales with our customers’ needs.
If you are passionate about performance, distributed systems, and large-scale reliability and thrive on diving deep into complex systems to make them faster and more efficient we want to hear from you!

Responsibilities:

• Lead the design, development, and evolution of performance testing frameworks.
• Collaborate with cross-functional teams and partner with stakeholders and lead discussions for technical solutions, including design and cost considerations.
• Define, implement, and scale realistic workloads that capture customer usage patterns (e.g., Git, API, CI/CD).Profile and analyze performance across the full stack: application (Ruby, Go), database (MySQL), caching (Redis), job systems (Resque/Sidekiq), and orchestration layers (Nomad, containers).
• Partner with engineering teams to identify, reproduce, and resolve performance bottlenecks.
• Establish performance baselines and regression detection in CI/CD pipelines.
• Design experiments to evaluate system scalability, concurrency, and fault tolerance.
• Provide deep technical guidance and mentorship on performance methodology across the org.
• Collaborate with support and reliability teams to reproduce customer workloads and drive fixes upstream.
• Author clear technical documentation and present findings to senior leadership and customers.
• Create and guide others in building a performance testing roadmap for Enterprise as a whole that includes defining success metrics and integrating customer feedback for continuous improvement.
