We're looking for an experienced backend engineer to design and build massively scalable, highly available services that power experiences for Apple customers.\nDescription\nAs a senior member of the Services Engineering Team, You'll build and operate high-throughput, low-latency backend services that ingest, process, and serve data at scale across a range of mission-critical workloads - from real-time transactions to analytics and content delivery. You'll also help evolve a multi-tenant platform, including AI/ML-powered services, by shipping new capabilities, scaling what exists, and applying distributed-systems best practices from design through production.\nMinimum Qualifications\nMaster's degree in Computer Science or a related field\n8+ years of professional software development experience building scalable, distributed systems in production\nExperience building, authoring, and operating large-scale, multi-tiered distributed systems and customer-facing web services: including API design, authentication, authorization, scaling for high availability, concurrency, and reliability.\nStrong understanding of concurrency and multi-threaded programming, fundamental data structures, and efficient algorithm design\nStrong proficiency in Java; working knowledge of a second systems language (Go, C++) is a plus. Solid OO analysis and design skills.\nStrong proficiency in application frameworks (Spring boot)\nHands on experience with JVM performance tuning and profiling - GC selection/tuning, JFR, async-profiler, heap/thread-dump analysis for low-latency services.\nHands-on with async and reactive JVM stacks: Netty, Project Reactor, RxJava, Vert.x, or Micronaut/Quarkus.\nRigorous testing discipline with JUnit 5, Mockito, AssertJ, Testcontainers, and contract testing.\nHands on experience with build and dependency management with Gradle\nDeep understanding of transactional consistency models - ACID semantics, with deep knowledge of tradeoffs between relational and NoSQL database technologies\nExpertise with synchronous and asynchronous network I/O and RPC frameworks (gRPC)\nExperience building and maintaining CI/CD pipelines (e.g., Jenkins, GitHub Actions, GitLab CI, or similar) for automated testing, build, and deployment of production services.\nExperience with AWS or GCP and cloud-native tooling (Docker, Kubernetes) in the context of deploying scalable production grade services.\nExperience with event streaming and queueing systems (specifically Kafka) and stream processing frameworks and high-throughput, append-only write paths for durable, queryable historical records.\nHands on Experience of leveraging data storage (Iceberg, Cassandra) and caching technologies (Redis) in Production services\nHands on experience with Serialization/schema tooling: Jackson, Protobuf, Avro, and Schema Registry\nExperience identifying, triaging, and remediating security vulnerabilities in production services (dependency management, secure code review, threat modeling).\nPreferred Qualifications\nSelf-motivated, with strong collaboration and communication skills, and experience in a fast-paced, agile environment\nExperience with machine learning systems, ML frameworks, libraries and algorithms\nFamiliarity with deployment and optimization of Large scale Production grade AI Services that require GPUs in the path of the transaction.\nHands-on experience deploying, serving, and optimizing LLMs or ML models directly in the transaction/request path\nExperience with security and cryptography (e.g., TLS, X.509 certificates) identity and access management protocols (OAuth2/OIDC/SAML), and secure token/session lifecycle management.","description_format":"text","description_chars":3759,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating
