Senior Software Engineer

The Developer Experience (DX) organization is seeking a Senior Engineer to join the Build and Test team, part of the group responsible for the foundational systems that power GitHub's internal development workflows.

DX focuses on improving how GitHub engineers build, test, and ship software across the company—operating at significant scale and complexity.

Our work spans CI/CD platforms, developer tooling, virtualized infrastructure, and the paved paths that enable teams to move quickly while maintaining reliability and security.

The Build and Test team owns the core build and continuous integration systems used across GitHub.

We provide the tooling, services, and operational support that allow engineers to deliver changes to production safely and efficiently.

This includes running highly available, company-wide CI platforms; partnering closely with application and platform teams to improve reliability and performance; and continuously reducing friction in the developer workflow.

The team plays a critical role in maintaining trust in GitHub's build and test infrastructure while balancing speed, scale, and stability.

GitHub's continued growth brings both opportunity and complexity.

As a Senior Engineer in this role, you will work within a distributed team operating mission-critical systems in a fast-moving environment.

You'll work closely with engineers across the company to improve CI reliability, reduce test flakiness, respond to incidents, and evolve our platforms to meet the needs of a rapidly scaling organization.

This role blends technical leadership, deep engineering expertise, and operational ownership, with a direct impact on the daily experience of GitHub engineers and the quality of the products used by millions of developers worldwide.

• Collaborate with engineering teams, product management, customers, and engineering leadership to align on and understand the problems we want to solve.
• Drive technical solutions to GitHub's most critical problems, often unblocking others through design guidance and hands-on contribution, via real-time conversations in Slack or Zoom and with asynchronous communication in GitHub Issues, PRs, Discussions, and Projects.
• Communicate effectively to stakeholders and leadership on technical direction, progress, and risks.
• Partner across the team and with stakeholders, building relationships, and identifying technical opportunities and areas of improvement.
• Driving good architectural design outcomes, secure and resilient systems, and quality code.
• Iteratively shipping features and bug fixes, balancing speed to market with future velocity.
