Summary
Imagine what you could do here. At Apple, new ideas become great products, services, and customer experiences quickly. Bring focus, rigor, and leadership to your team and shape the evolution of Apple’s Kafka ecosystem. Apple is seeking an experienced software engineer, responsible for building, contributing to, and managing the core Apache Kafka infrastructure that powers Apple’s critical services. This team develops, maintains, and scales Kafka internally while actively contributing to the upstream open-source project. Your work will impact all users of Apple products and services and ensure the reliability, performance, and evolution of Apple’s messaging platforms.
Description
Apple’s Kafka organization develops messaging systems that are reliable, scalable, and performant. The role focuses on building and operating Apple-scale Kafka deployments while contributing directly to Kafka internals, including brokers, client libraries, replication, fault tolerance, partitioning, and system-level optimizations. You will design and implement core features, drive performance and reliability improvements, and take ownership of critical components across the Kafka ecosystem. The work spans both internal platform needs and upstream open-source contributions, with responsibility for high-quality code, rigorous engineering standards, and operational excellence in production environments
