Senior Software Engineer (Java Backend) ,Retail Engineering

Apple is a place where extraordinary people gather to do their best work. Together, we craft products and experiences that people once couldn't have imagined — and now can't imagine living without.

Do you want to help build some of the largest and most consequential enterprise and customer technology systems in the world? Join Apple’s Information Systems and Technology (IS&T) organization. IS&T is the engine behind everything Apple does for customers and for the people who build for them. It’s Apple’s 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, IS&T makes the impossible feel effortless.Do you love building solutions to handle global complexity and immense scale? Imagine what you could do here.

Retail and Marcom Engineering, an IS&T team, builds and operates the systems and experiences that connect Apple's products with its customers. The team owns the technology behind both Apple's online and physical stores and drives the interactive marketing experiences and tools that keep creative operations moving. Together, those functions deliver the technology behind every product story Apple tells and every purchase a customer makes.

You'll operate at the intersection of engineering, architecture, and leadership — influencing solution design, mentoring developers, and driving best-in-class technical outcomes. You'll architect and design scalable microservices using Spring Boot, Spring Cloud, and RESTful APIs, and own systems where reliability, latency, and throughput genuinely matter. The ideal candidate combines deep backend engineering rigor with curiosity about where the field is heading — someone who's as comfortable reasoning about circuit breakers and backpressure as they are experimenting with LLMs and agentic workflows to solve real engineering problems. If you're passionate about contributing to what's next, we want to hear from you.
