About The Position

Join Apple’s Information Systems and Technology (IS&T) organization, which supports Apple devices, secure transactions, and the technology used by Apple customers and employees. Customer Systems builds and operates technology for Apple’s customer support experience, including contact center operations, Genius Bar software, and the AppleCare online support platform, which handles 6 billion visits per year.

In this role, you will design and build microservices for low-latency, high-throughput customer experiences used by more than a million people daily across Apple Support websites, iOS apps, and phone-based frontends. You will own feature delivery from technical design through implementation, testing, deployment, and production observability, while helping drive engineering practices and architecture across the team.

• At least 5 years of professional software development experience; longer experience is preferred.
• At least 2 years of experience with Java, including concurrency, memory management, and performance optimization.
• Proficiency in object-oriented programming principles, data structures, algorithms, and software design patterns such as GoF, with a focus on testable, maintainable, and extensible backend code.
• Experience building production applications with the Spring ecosystem, including dependency injection, auto-configuration, reactive programming with WebFlux, and Spring-based microservices patterns.
• Solid understanding of JVM internals, including garbage collection, memory allocation, JIT, and JNI.
• Experience designing, implementing, and shipping high-scale, high-performance, highly available, fault-tolerant, and secure cloud-based distributed systems.
• Solid knowledge of networking concepts, protocols, and infrastructure, including HTTP/HTTPS, TCP/IP, CDN, load balancing, edge computing, DNS, and Zero Trust architecture.
