We are the Foundational Security team in Apple Services Engineering (ASE). We secure the low-level foundations of Apple's datacenter fleet: hardware-backed trust, disk encryption, and the systems used to manage every server below the operating system. We're looking for a senior engineer to take technical ownership of the platform that manages our baseboard management controllers. You'll set its engineering and security bar, shape how access is granted and verified, and lead its move toward modern, standards-based management. You'll work closely with datacenter operations, SRE, hardware, network and detection teams, and become the go-to expert on managing Apple's fleet securely.
