Pre-Silicon Infrastructure Software Engineer, Core OS

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, you'll be an essential part of our brand's personality, 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, visionOS, and tvOS. By crafting these distinct, holistic user experiences, you'll continue to uphold and advance the excellence people expect from Apple devices. \\n\\nThe Pre-Silicon Evolution team within Apple's CoreOS organization is searching for dedicated software engineers to develop software infrastructure and tooling for Apple Silicon SoCs. Our team lives at the intersection of hardware and software, and we push the boundaries of full-system, pre-silicon simulation to enable software development for Apple products during the earliest phases of their development.

The software tooling and cloud infrastructure we develop is used across Apple's hardware and software organizations. We design technologies that enable development and testing of both hardware and software features for future Apple products to ensure that they work seamlessly together before they are manufactured. As a Pre-Silicon Infrastructure Software Engineer, you will play a significant part in crafting a simulation environment, define bring up processes, create new tools and services used across the organization for a broad range of upcoming Apple devices.
