Senior Site Reliability Engineer, Apple Data Platform SRE / Apple Services Engineering

At Apple, we believe that innovation flourishes in an environment where ideas are challenged, collaboration is encouraged, and technology is pushed to its limits. This environment is only possible when diverse minds come together, bringing unique perspectives and experiences. Our people and their ideas inspire innovation in everything we do. Imagine what you could accomplish here! Join Apple and help us make the world a better place. As a principal contributor and technical lead in our Apple Data Platform (ADP) SRE organization, you will apply SRE principles as you mentor and partner with our engineers and partner teams, ensuring large-scale analytics infrastructure runs reliably and efficiently. This role focuses on driving reliability standards, architectural consistency, and engineering excellence across peer SRE teams and partner engineering organizations — spanning Hadoop, HBase, Spark, Data Lakes, and Airflow ecosystems — through technical leadership, cross-functional alignment, and the development of platform-wide tooling, observability, and operational practices that raise the reliability bar for all of ADP. This role includes production on-call responsibilities. ## Description Apple Service Engineering (ASE) teams build and scale the platforms and infrastructure behind many of Apple’s services — including iCloud, iTunes, Siri, and Maps.
