The people here at Apple don't just build products, we build the kind of wonder that revolutionise entire industries. Imagine what you could do here! Do you have a passion for understanding how each line of code affects all the others? In the Core Operating Systems group ensuring 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, complete user experiences, you'll continue to uphold and advance the excellence people expect from Apple devices! The Darwin Runtime team in Core OS is looking for enthusiastic engineers interested in developing low-level system technologies for Apple's operating systems.

Description

The Darwin Runtime team is responsible for building the low-level runtime technologies like Grand Central Dispatch (GCD), secure inter-process communication systems, memory allocator, threading library, and concurrency and synchronization primitives. The team operates at the intersection of operating systems, programming language design, systems security, and high-performance computing. As a Software Engineer on the team, you'll work closely with kernel engineers, security architects, and framework developers to deliver foundational technologies that enable Apple's next-generation computing platforms.The ideal candidate should be self-motivated and effective in operating independently, with a desire to learn and develop technical leadership. Team members are welcome and encouraged to participate in design discussions, code reviews, and development across multiple technologies. Our environment fosters technical innovation, meaningful technology ownership, and a liberating amount of autonomy!","responsibilities":"You will be responsible for working on a range of technologies that form the foundation of Apple's operating systems.
