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 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, holistic user experiences, you’ll continue to uphold and advance the excellence people expect from Apple devices. The Mac Platform Team within Apple's CoreOS organization is looking for a talented embedded software engineer to help with pre-silicon simulation, early silicon support and development of the boot firmware and software for future generations of Macs. You will have the opportunity to work on core technology and make a major impact in the way that Apple develops and ships Mac products. Our environment champions product innovation, rapid product iteration, and a liberating amount of autonomy. We are looking for detail oriented engineers with a passion for quality who want to define and build future Mac systems.

Key Qualifications

  • Working knowledge of processor architecture & micro-architecture (ARM preferred)
  • Proven experience in hands-on development and troubleshooting of boot-loaders, mask ROM on embedded targets
  • Solid programming experience in C or C++. Understanding of ARM assembly.
  • Previous experience writing embedded device drivers
  • Previous experience with platform bring-up or porting of operating systems
  • Previous experience with hardware and processor simulation and emulation environments
