The Darwin Debug Development team in Core OS is looking for enthusiastic engineers interested in developing system software for Apple’s operating systems. Darwin is the UNIX-like foundation at the heart of all Apple’s operating systems, stretching from the kernel up through low-level user components. The Darwin Ecosystem team is responsible for ensuring this foundation is adaptable for use in new products and environments. By creating an ecosystem of technologies used by a range of Apple’s product teams, the team has a meaningful role in enabling new products and experiences throughout Apple. The team focuses on key kernel technology areas such as CPU scheduling, power management and threading models which are key to delivering great performance and battery life 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.
