About The Position

The Apple Services Engineering (ASE) Commerce group is looking for an extraordinary Senior Backend Java Engineer to join our Payments Experience team. We build the transactional engine that powers the App Store, Apple Music, Apple TV+, and more. As the highest-volume digital content store in the world, our platform serves countless transactions daily across more than 130 countries. We are driven by a single goal: providing a flawless, secure purchase and subscription experience for millions of customers and developers globally. DESCRIPTION As a key member of the Payments Experience team, you will build robust backend services shared across iPhone, Mac, and Web. Your work will directly support the immense transactional volume of the App Store (1P and 3P) and Apple media products globally, requiring systems built for uncompromising data integrity, scalability, high availability, fault tolerance, and security. Beyond implementation, you will drive the architecture and design of top-level user-facing features. We are looking for an engineer who can identify and build highly reusable components that scale elegantly across diverse scenarios, domains, and global regions. Your technical foundation should include in-depth experience developing large-scale, relational database-backed Java applications with deep object-oriented expertise. While mastery of relational databases and Java services is essential, experience with Cassandra or other NoSQL technologies is a strong plus. Because our reach is broad, you will partner closely with a diverse array of cross-functional teams across Apple to bring these features to life. If you thrive on the excitement and challenge of building systems exposed to throngs of transacting users, you will find a fast-paced, rewarding environment here. Join us in collaborating to deliver amazing products and features that impact Apple customers worldwide.
