About this role

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. Sales and
Operations Engineering is part of IS&T and drives the technology behind Apple's
global operations, sales, and supply chain. The team connects the systems that
move products from factory to customer — bridging sales platforms with the
operational infrastructure that keeps Apple running at scale and ensuring
Apple's technology and business priorities move in lockstep.

DESCRIPTION

As a Senior Software Engineer, you will design, build, and scale enterprise
back-end systems that power critical Apple products and services. You will
develop, document, and maintain production code in Java — from architecture
through implementation — while independently owning complex, often ambiguous
technical problems and driving cross-functional solutions with minimal guidance.
You’ll be hands-on across the stack: designing APIs and microservices, working
with core Java internals, optimizing data layer performance, and ensuring
secure, reliable deployment. You will interface directly with business leaders,
application owners, other developers, and project managers to take projects from
inception to completion, and you’ll be responsible for delivering on commitments
on time. Beyond individual contribution, you will act as a key technical mentor
on your team, shaping architectural direction and raising the technical bar for
those around you — extending your influence across related disciplines and
organization-wide initiatives. This role calls for someone comfortable working
independently and under pressure on sophisticated, large-scale system
architecture.

MINIMUM QUALIFICATIONS

B.S. in Computer Science, Computer Engineering, or a related technical field, or
equivalent work experience. 8+ years experience in designing and developing
scalable enterprise level back end solutions. 4+ years experience with Java,
including proficiency in concurrency, memory management, and performance
optimization techniques. Proficiency in OOP principles, data structures,
algorithms, and software design patterns (e.g. GoF), with a proven focus on
implementing testable, maintainable, and extensible backend code. Java Ecosystem
- Experience building production applications with the Spring ecosystem (e.g.
Spring Boot, Spring MVC, Spring Security, Spring Data, Spring Cloud, etc.),
including proficiency in dependency injection, auto-configuration, reactive
programming with WebFlux, and designing microservices using Spring-based
patterns. Java Ecosystem - Solid understanding of advanced JVM internals (e.g.
garbage collection, memory allocation, JIT, JNI, etc.). Distributed Systems &
Architecture - Experience in API design and implementation, including
proficiency 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. Distributed Systems & Architecture - Experience with
message-driven and event-driven architectures, including proficiency in
messaging systems (e.g. Kafka, RabbitMQ, ActiveMQ, etc.), event sourcing, CQRS
patterns, and designing reliable asynchronous communication between distributed
services.

PREFERRED QUALIFICATIONS

Track record of leading software projects within a team as a tech lead (TL),
while mentoring software engineers. Hands-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 processes.
Security - Experience implementing authentication and authorization systems,
including proficiency in identity protocols (e.g. OAuth2, OIDC, SAML, JWT,
etc.), single sign-on (SSO) architectures, role-based and attribute-based access
control (RBAC/ABAC), and integration with identity providers and directory
services. AI/ML - Experience with Natural Language Processing and Generative AI
systems, including Large Language Models (LLMs), Retrieval Augmented Generation
(RAG) architectures, embedding pipelines, vector databases (e.g. Pinecone,
Weaviate, pgvector, etc.), fine-tuning, and prompt engineering for production
applications. Distributed Systems & Architecture - Experience with caching
strategies and in-memory data technologies (e.g. Redis, Memcached, Hazelcast,
Ehcache, etc.), including proficiency in cache invalidation patterns,
distributed caching architectures, and session management for high-throughput
applications. Databases - Experience using relational (e.g. Oracle, Postgres,
MySQL, etc.) and NoSQL (e.g. Cassandra, MongoDB, etc.) databases, including
proficiency in schema design, query optimization, performance tuning (e.g.
execution plan analysis, indexing strategy, and query rewriting).
