Payments are at the heart of Apple's ecosystem — and we're reimagining how they work. The Payments Engineering team is building a modernised, cloud-native platform engineered for high throughput, elastic scalability, and the reliability that Apple's global transaction volume demands. If you love solving meaningful problems that impact millions of people, we want to hear from you.

The Payments Engineering team is part of the Wallet, Payments & Commerce (WPC) organisation. Our core mission is to build and maintain the foundational payment rails that enable all payment transactions across Apple's ecosystem — including the Apple Online Store, Apple Retail Stores globally, and the Apple App Store. We operate at global scale, handling Apple's immense transaction volume, and are at the forefront of fintech innovation, setting new payment trends and collaborating with leading fintech partners worldwide. Our team is growing and we are looking for engineers who are passionate about their craft, excited by the challenge of building systems at scale, and comfortable working in a dynamic, evolving environment.

Partner closely with Product, Security, and Platform teams across multiple time zones to deliver cohesive, well-integrated solutions
Champion engineering excellence — continuously evaluating new technologies, patterns, and practices to raise the bar for the team
Participate in on-call rotations and take ownership of the reliability, observability, and operability of the services you build
Drive incident response and post-mortems, translating learnings into systemic, lasting improvements
