Are you a big-picture problem solver who loves setting high-reaching goals? Do you have a passion for understanding how each line of code affects all the others? In the Core Operating Systems group, you’ll ensure 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, well-rounded user experiences, you’ll continue to uphold and advance the excellence people expect from Apple devices. Apple’s CoreOS organization is seeking a highly motivated test engineer to join the Core Darwin QA team. We recognize that the quality of our software is only as good as that of our testing. The right candidate for this position enjoys finding creative and unexpected ways to torture bits. Your responsibilities will include developing a good understanding of ongoing development efforts across the operating systems teams; working alongside OS developers to create and implement comprehensive test plans during feature development; maintaining and extending automated test harnesses and infrastructures; writing automated tests for kernel and user space features; and generally enabling an increased quality and quantity of test coverage for various parts of the OS.
