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 industry.

This 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 people.

The 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 software engineers who are ready to take on large, complex systems problems and deliver high-quality solutions within Apples Build System. Previous background with systems engineering experience, a drive to solve hard distributed systems problems, and the ability to develop depth of expertise in the complexity of builds at Apple will ensure your success.

Youll work as part of a collaborative team and partner with other teams across Apple to optimize distributed scheduling, ensure build correctness, develop caching strategies, and continuously improve build performance.

From conception through to delivery and operation, youll tackle intricate problems, build new features, develop testing strategies, measure outcomes, and deliver highly-available solutions that run on large-scale infrastructure. Once delivered, you will drive continued improvements through data analytics that will measure impact of your feature and drive up reliability of the system. This will also ensure minimal interruption during your time on call supporting our production systems. Ultimately, this will drive what matters: Improving Apples build pipelines and Software development at Apple.2+ years of software engineering experience in developer tooling, backend, infrastructure, or systems contexts Experience developing testing strategies and operating software in production environments using metrics, telemetry, and performance data to evaluate system behavior, identify bottlenecks, and drive iteration on systemsDistributed systems, scheduling, or caching at scale Observability, monitoring, or SRE practices Leveraging AI-assisted development tools to improve personal and team productivity Build systems (Swift Build, Bazel, Buck, etc.)
