GitHub Actions powers automation for millions of developers worldwide, processing billions of CI/CD jobs monthly, from simple builds to complex deployment pipelines spanning multiple environments and platforms including macOS. Our team owns the macOS platform within Actions, working across cloud infrastructure, networking, security, and distributed systems to deliver a reliable and performant experience for developers. We’re looking for a hands-on Staff Software Engineer to set technical direction for the macOS platform, lead cross-team efforts to deliver durable platform capabilities, and raise the bar on scalability, reliability, and operational excellence at scale. You’ll identify the highest-leverage problems, drive alignment across stakeholders, and guide design and execution from early architecture through rollout and long-term operational ownership, including observability, incident response readiness, and continuous improvement.
Responsibilities:Design, develop, test and ship high-quality technical solutions that scale across multiple GitHub services and become intimately familiar with the systems you build and take pride in writing maintainable code.
Provide technical leadership, mentorship, pairing opportunities, and code reviews to encourage the growth of others; support teams in producing extensible and maintainable code, ensuring integration with downstream dependencies and adherence to quality standards.
Own and advocate for the health and quality of the systems that the team builds, including participating in on-call for first responder rotations and live incidents.
Write architecture briefs and proposals and carry out code experiments.
Design and implement APIs to facilitate seamless integration between software components.
Utilize CI/CD tools to set up automated pipelines for continuous integration and delivery.
Collaborate with cross-functional teams and partner with stakeholders and lead discussions for technical solutions, includindesign and cost considerations.
Create and guide others in 1) developing clear testing plans to assure solution quality, reliability, and performance; 2) defining success metrics; and 3) integrating customer feedback for continuous improvement; all while ensuring system architecture meets security and compliance standards.
Maintain executional and operational excellence within and potentially across teams/organizations.
Apply debugging tools and telemetry to verify assumptions, proactively resolve issues, and optimize code performance and maintainability.
Drive and support 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.
