Senior Software Engineer - Distributed Build Systems

Apple’s 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.

Do you have experience in Test Planning (Quality assurance practices)?, We’re looking for senior software engineers who combine deep technical ability with strong engineering judgment and the ability to lead through influence. In this role, you’ll shape the platform by identifying and solving the most important problems, while raising the engineering bar for the team.

You’ll own technically complex and high-impact projects to optimize distributed scheduling, ensure build correctness, develop caching strategies, and continuously improve build performance at scale. You’ll set technical direction, make design trade-offs, and ensure high-quality outcomes. Post-delivery, you’ll use data and telemetry to measure impact, drive reliability improvements, and support production systems on call.

Beyond individual contributions, you’ll 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. You’ll help less-experienced engineers grow by providing thoughtful code review, facilitating design discussions, and creating opportunities for others to take on challenging work.

You’ll also need to communicate effectively across organizational boundaries, articulating technical trade-offs to stakeholders, aligning efforts across teams, and representing the team’s technical perspective in cross-functional planning.

Preferred Qualifications

Distributed systems, scheduling, or caching at scale

Concurrency, systems programming, or performance optimization

Build systems (Swift Build, Bazel, Buck, etc.)

Observability, monitoring, or SRE practices

Leveraging AI-assisted development tools to improve personal and team productivity

Making risk-informed decisions about changes to systems with broad user impact

Driving architectural decisions that balance near-term delivery with long-term system health

• Communicating technical trade-offs to diverse audiences, including those outside your immediate domain

Minimum Qualifications

5+ 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 systems

Experience owning the delivery of projects with significant scope, including defining approach and driving completion

Experience mentoring engineers or raising team capabilities through code review, design guidance, or knowledge sharing
