People at Apple don’t just build products — they craft the kind of experience that have revolutionized entire industries. The diverse collection of our people and their ideas inspire innovation in everything we do. Imagine what you could do here! Join Apple, and help us leave the world better than we found it. The Apple Services Engineering (ASE) team builds and provides systems and infrastructure that fuel Apple’s services (such as iCloud, iTunes, Siri, and Maps). We are the foundation on which Apple’s software developers build the products that our customers love. We are looking for passionate and talented Site Reliability Engineers to continue our focus in providing our customers the highest quality Apple Services experience. Our services have to scale globally, stay highly available, and "just work.” If you love designing, engineering and running systems and infrastructure that will help millions of customers, then this is the place for you!
Observability infrastructure is BIG. Operating at our scale, across multiple geographically dispersed data centers and servicing hundreds of millions of users presents unique challenges. As an SRE at Apple, you'll need to solve these problems using data, teamwork, and your own expertise. SREs at Apple own the full infrastructure stack; from device driver performance debugging to content delivery network traffic management — our responsibilities are both broad and deep. Observability runs its systems on Linux and Kubernetes. We run a mix of open source, vendor licensed, and internally developed tools to perform functions such as system configuration management, provisioning, software deployment, logging, and monitoring. You'll learn these tools and have opportunities to improve them. Our team is collaborative; we work closely with the development teams we support to deliver the best results for Apple. We think critically and strive to balance the best solution with the need to get things done for each engineering challenge we face. Good ideas are heard and results are rewarded. Observability SRE is a small team with huge scale. We serve as central Telemetry and Logging for the Services organisation, which powers most of the customer-facing Apple services, like iCloud.
