Apple's Software Developer Workflows team delivers fast, reliable CI systems that make Apple's software easier to develop and ship. We believe that streamlined development unlocks creativity, innovation, and potential for developers.

We're looking for a senior engineer to help drive the foundational services that power Apple's continuous integration, the systems that let Apple's software engineers build, test, and validate code changes s is a role for someone who is a go-to expert in backend systems, takes the lead on major features, spots where the platform needs to improve, and takes real ownership of how reliably we operate.

We value diverse perspectives and unique skills. More than specific experience, we seek an engineer passionate about building great software, continuous learning, and solving complex technical problems.

In this role, you'll lead across the backend services that form the backbone of Apple's CI infrastructure, partnering closely with the UI team where backend and frontend meet. You'll architect systems that scale reliably, set the direction for how services integrate with diverse workflows, and drive improvements to the developer experience for teams across the company. As a technical leader, you won't just contribute to the platform, you'll identify where it needs to go next, rally the team around that direction, and own the outcomes.

Your work will directly shape how efficiently Apple's engineers can validate and ship code.

Success requires flexibility, proactivity, and thriving in a supportive environment full of challenging problems. You'll bring excellent judgment for timely, high-stakes technical decisions, the ability to lead design discussions and build alignment across teams, and the technical depth to make informed tradeoffs on systems that must stay reliable 'll also raise the bar operationally, championing strong on-call practices, incident response, and the long-term health of the services we run, and mentor engineers as you set the standard for quality.
