Sr. Software Engineer, Enterprise Technology Services

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 Technology Services (ETS) is part of ISu0026T and delivers global-scale platforms and services that keep Apples operations secure and running. The team manages identity device security and anti-abuse platforms covering everything from manufacturing and repairs to software updates and activations. ETS also oversees supply chain manufacturing and partner integration platforms protecting data on more than 2.5 billion devices worldwide. And when Apple prepares for a global product launch ETS owns the systems that ramp factory production managing serial numbers network credentials and verified software.

Identity Management Services (IdMS) builds and operates the identity platform behind Apple Account the sign-in and account system for every Apple service from iCloud the App Store and Apple Music to Apple Pay FaceTime and the Online Store. The team designs secure high-scale distributed Java services that handle billions of authentication and account lifecycle requests every a Software Development Engineer on this team you will design and build scalable identity services and high-performance REST and RPC APIs spanning authentication adaptive MFA and user lifecycle. You will own features end to end from architecture and design through implementation contract and integration testing and production support while improving the reliability latency and observability of systems that are never idle. You will also help bring ML and generative AI capabilities into identity workflows such as adaptive authentication and anomaly detection partnering with QE platform product and design teams along the way.
