Sr Software Engineer, Customer Systems

Do you want to help build some of the largest and most consequential enterprise and customer technology systems in the world Join Apples Information Systems and Technology (ISu0026T) 0026T is the engine behind everything Apple does for customers and for the people who build for them. Its Apples central nervous system. Supporting 2.5 billion active Apple devices processing billions of secure transactions and keeping the technology that defines modern life running flawlessly ISu0026T makes the impossible feel effortless.

Customer Systems is part of ISu0026T and drives the technology behind Apples customer support experience from contact center operations to the software powering the iconic Genius Bar. The team also builds and operates AppleCares online support platform which handles 6 billion visits per year delivering seamless high-quality support to Apple customers around the and build microservices powering low-latency high-throughput customer experiences serving over a million users daily across Apple Support websites iOS apps and phone-based frontends.

Own end-to-end delivery of features from technical design and implementation through testing deployment and production engineering best practices code reviews unit/integration testing CI/CD pipeline improvements and documentation raising the bar for the broader non-blocking event-driven service pipelines that handle millions of concurrent requests with resilience and back-pressure to API design and contract-first development ensuring backward compatibility and clean integration across service boundaries.n
