Staff Software Engineer, Retail and Marcom Engineering

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 and Marcom Engineering an ISu0026T team builds and operates the systems and experiences that connect Apples products with its customers. The team owns the technology behind both Apples 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.

Retail Engineering Foundations builds and operates the platform services that power Apple Retails data and application infrastructure tooling used across retail systems with a focus on reliability consistency and scalability. As a staff-level Software Engineer on this team you will architect design develop test document improve and maintain code mostly in Java (and other languages as needed) partaking in every aspect of your projects from planning through implementation and future iterations with an extended role in designing solutions and leading software projects.

B.S. in Computer Science Computer Engineering or a related technical field or equivalent professional work experience.n8 years proven experience developing software in a professional capacity. Longer experience strongly preferred.n4 years proven experience with Java including mastery in concurrency memory management and performance optimization in OOP principles data structures algorithms and software design patterns (e.g. GoF) with a proven focus on implementing testable maintainable and extensible backend building production applications with the Spring ecosystem (e.g. Spring Boot Spring MVC Spring Security Spring Data Spring Cloud etc.) including mastery in dependency injection auto-configuration reactive programming with WebFlux and designing microservices using Spring-based with cloud platforms (e.g. AWS GCP Azure etc.) including mastery in IaC containerization and orchestration using industry-standard tools (e.g. Terraform Docker Kubernetes etc.).nExperience designing implementing and shipping high-scale high-performance highly available fault-tolerant and secure cloud-based distributed with message-driven and event-driven architectures including mastery in messaging systems (e.g. Kafka RabbitMQ ActiveMQ etc.) event sourcing CQRS patterns and designing reliable asynchronous communication between distributed using relational (e.g. Oracle Postgres MySQL etc.) and NoSQL (e.g. Cassandra MongoDB etc.) databases including mastery in schema design query optimization performance tuning (e.g. execution plan analysis indexing strategy and query rewriting) and understanding of database transaction foundations across systems.

Track record of leading software projects that span multiple distributed teams as a tech lead (TL) while mentoring senior-level software -on experience leveraging GenAI coding tools (e.g. Claude Copilot Codex) to accelerate the software development lifecycle enhance code quality and streamline debugging and testing with search and indexing technologies (e.g. Elasticsearch OpenSearch Solr etc.) including designing search architectures index optimization query tuning and implementing full-text search for large-scale -level expertise in observability and monitoring including implementing comprehensive solutions using modern tools (e.g. Splunk Prometheus Grafana APM platforms CloudWatch etc.) for large-scale distributed -level knowledge of networking concepts protocols and infrastructure (e.g. HTTP/HTTPS TCP/IP CDN load balancing edge computing DNS Zero Trust architecture etc.).nExpert-level understanding of advanced JVM internals (e.g. garbage collection memory allocation JIT JNI etc.).nExperience in API design and implementation including mastery in RESTful API principles gRPC GraphQL contract-first design (e.g. OpenAPI/Swagger Protobuf etc.) API versioning strategies gateway patterns rate limiting and designing APIs for backward compatibility and long-term evolution.
