The Darwin Systems team within Apples CoreOS organization is responsible for delivery of a high-quality and performant kernel for just about every one of Apples 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; and now in visionOS and Apples Cloud. These are the devices owned by your friends and family; and hundreds of millions of devices beyond those. We ensure every aspect of the kernel and other system software are top class: features, performance, stability, security… This position requires a solid understanding of operating systems fundamentals, including kernel design and implementation. The virtual memory team is in charge of page management, mechanisms such as copy on write, low-memory process killing, swap… We work with every layer of the stack: from hardware all the way up to applications and successful engineers will be able to dig deep into details and work with other engineers to solve problems, find opportunities to keep on improving our stack and design to improve our customers experience. As Moores law is slowing down, effective management of resources is becoming more and more important. We work closely with all product teams across Apple to provide them with a modern, efficient operating system that allows them to ship the kinds of quality products that our customers expect.
