Weekly Hours: 37.5
Role Number:200346198
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. We are working to take the build and test process of the low-level components of iOS, macOS, watchOS and tvOS to the next level (think kernel and low-level libraries). We don’t have all of the answers on how to do that yet, perhaps you do? We are exploring, measuring and trying new things. We are responsible for validating nearly a quarter of all changes that go into our OS releases and affect 1 billion+ customers, so this isn’t just a theoretical exercise. We won’t be satisfied with anything less than outstanding!

  • Ability to work with the engineering team to root cause failures on short/tight cadence.
  • Execute nightly regression test suites on multiple devices and raise failures in a timely manner
