Apple

We’re the team that designs and develops the operating system for the Secure Enclave used in iOS, tvOS, watchOS, and macOS devices. We develop the full software stack, including the L4 microkernel, runtime libraries, hardware drivers, and more. We work very closely with Apple’s Silicon Engineering Group to help design the Secure Enclave hardware. This is a great place to work if you’re into some combination of embedded, operating systems, and security.
