Cupertino, CA
  • Job Code

Are you a big-picture thinker who loves setting ambitious goals? Do you have a passion for understanding how each line of code affects all the others? In the Core Operating Systems group, you'll ensure the OS is inseparable from each device's identity as a whole. That's because this group is committed to building fully integrated operating systems that combine hardware, software, and apps into a single Apple experience. Your dedication to cross-disciplinary collaboration will help develop groundbreaking technologies, such as iOS, macOS, watchOS, and tvOS. By crafting these distinct, holistic user experiences, you'll continue to uphold and advance the excellence people expect from Apple devices

The Core Kernel team within Apple's CoreOS organization is responsible for delivery of a high-quality and performant kernel into just about every one of Apple's products. Our software runs on your wrist as part of watchOS; in your pocket with iOS; on your desk in macOS; in your living room with tvOS; on the devices owned by your friends and family; and hundreds of millions of devices beyond those

This position requires a rock solid understanding of operating systems fundamentals, as well as experience in kernel design and implementation. We deal in all of the traditional kernel subsystems, e.g. virtual memory, scheduling, IPC, etc, and also serve as expert system sleuths up and down the entire Apple stack. Our company is one of the last vertically integrated systems shops remaining, and as such our engineers have the unique opportunity to roam the system freely, from iOS silicon design all the way up to Apps and the cloud

  • Design and implementation responsibility for a major project
  • Demonstrated creative and critical thinking capabilities and troubleshooting skills
  • In-depth knowledge of kernel internals
  • Familiarity with modern processor architecture (e.g. memory hierarchy, multicore, multithreading, etc)
  • Highly professional, with the ability to multitask and deliver solid work on tight schedules


Work with a highly skilled engineering team in the design, implementation and support of kernel technologies.
