Senior Software Engineer Distributed Build Systems

Apples distributed build platform is central to the development and delivery of every operating system and app we ship. Tens of thousands of engineers rely on it daily to develop software that ships to billions of customers a scale that has few peers in the role is part of the Software Engineering Developer Productivity team that builds and operates that platform working at the intersection of developer productivity and systems engineering to solve complex distributed systems and build automation challenges. Every performance improvement and correctness fix translates directly into faster more reliable software development for thousands of engineers across Apple and ultimately into better products for billions of challenges here go well beyond routine development. They demand creative thinking strong fundamentals and a drive to build solutions where none exist yet.

Were looking for senior software engineers who combine deep technical ability with strong engineering judgment and the ability to lead through this role youll shape the platform by identifying and solving the most important problems while raising the engineering bar for the own technically complex and high-impact projects to optimize distributed scheduling ensure build correctness develop caching strategies and continuously improve build performance at scale. Youll set technical direction make design trade-offs and ensure high-quality outcomes. Post-delivery youll use data and telemetry to measure impact drive reliability improvements and support production systems on individual contributions youll play a key role in elevating the team by mentoring engineers establishing engineering best practices improving development processes and contributing to a culture of technical rigor and continuous improvement. Youll help less-experienced engineers grow by providing thoughtful code review facilitating design discussions and creating opportunities for others to take on challenging also need to communicate effectively across organizational boundaries articulating technical trade-offs to stakeholders aligning efforts across teams and representing the teams technical perspective in cross-functional planning.
