Summary
The SWE Developer Foundations organisation builds technologies and tools to help software engineers at Apple to do the best work of their lives. Our team supports that mission by building innovative infrastructure and tools to provide engineers with capabilities to quickly & efficiently build and test their changes, supporting both the development lifecycle of their changes, as well as the end-customer product.
We are looking for distributed systems engineers to join our efforts. You'll work on profiling, improving & extending large-scale novel build and distributed systems to meet the needs of Apple's operating system engineers. If you have an interest in system software, cloud services, or developer tooling, then we have many exciting problems to work on!
You would join a small, tight-knit group of engineers who build exciting new technology and have fun while doing so. We are applying unique and innovative ideas to old problems and welcome new contributors who are excited by the opportunity to significantly impact the shape and direction of our product.
Description
As an engineer in SWE Developer Foundations, you’ll learn how Apple builds & releases software and you’ll be encouraged to research established distributed system techniques to apply to our unique domain in order to achieve high performance, reliability and long-term maintainability. You’ll have space to perform experiments, make recommendations, and ultimately changes, to our infrastructure to realise its full potential. You’ll then ultimately have a chance to present your work to our leadership team.
Responsibilities
At Apple, we believe accessibility is a fundamental human right. You’ll find that idea reflected in everything here — in our culture, our benefits and our digital tools. By welcoming as many perspectives as possible, we help you build a career where you feel like you belong.

- Have access to the engineers who create Apple’s full technology, tools, and operating systems stack.
- Here you’ll find that we:
- Provide a supportive, respectful, and balanced work environment.
- Value curiosity, and obsess over the customer experience.
- Have a wide range of experience, from new engineers to Apple veterans.
- Experience with building and operating distributed storage and/or distributed compute systems.
- Experience with high-performance, strongly typed languages such as Swift, Rust, C++, Scala, or others.
- Strong interest in distributed systems, reliability, and cloud services.
- Ability to efficiently develop, debug, and support new technologies in a changing environment.
- Experience with OS/Systems Programming fundamentals, particularly with respect to performance optimisation.
- Familiarity with the Swift-on-Server ecosystem.
- Familiarity with cloud compute/storage technologies like Kubernetes and Cassandra.
- Familiarity with application and service monitoring tools and techniques.
