## Job description

The OS Performance team is looking for a software developer with a keen understanding of app development and systems design to support our efforts building Apple's family of operating systems. Our work enables iOS, macOS, tvOS, and watchOS to perform well, and gives developers the platform they need to easily write great performing apps. A successful candidate may have experience with a specific layer of software (e.g. embedded, UI, server) but more importantly an interest in learning how the entire stack and flow of information works.

The ideal candidate would also not only understand the fundamentals of designing and implementing a performant application for iOS, macOS, tvOS, or watchOS, but also have an appreciation for using data to drive decision making in software development.
