About

• 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 Darwin Kernel Technologies 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. Darwin Kernel Technologies team focuses on key
• kernel areas such as IPC, process management and security which are key to
• delivering great performance and user privacy across all Apple devices. This
• position requires a solid understanding of operating systems fundamentals,
• including 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.

• DESCRIPTION

• Work with a highly skilled engineering team in the design, implementation and
• support of numerous kernel technologies. The role includes interacting with
• cross-functional teams across Apple to bring state-of-the art kernel and
• security enhancements to Apple’s products. Engineers also use various debugging
• tools and techniques to identify system issues and improve quality.

• MINIMUM QUALIFICATIONS
