Apple Services Engineering 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. ASE runs the majority of its systems on Linux. 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. 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! The Observability SRE organization is specifically tasked with enabling other teams to better understand their infrastructure and services, providing world-class observability capabilities.
