Senior SWE - Enterprise Technology Services

Apple IS&T’s infrastructure powers billions of transactions every day. At this scale, the systems we build must be resilient, observable, and extraordinarily efficient. We are looking for a Software Engineer with deep expertise in Go and distributed systems to join our team and help build the next generation of Observability Platform. Enterprise Technology Services (ETS) is part of IS&T and delivers global-scale platforms and services that keep Apple's operations secure and running. The team manages identity, device security, and anti-abuse platforms — covering everything from manufacturing and repairs to software updates and activations. ETS also oversees supply chain, manufacturing, and partner integration platforms, protecting data on more than 2.5 billion devices worldwide. And when Apple prepares for a global product launch, ETS owns the systems that ramp factory production — managing serial numbers, network credentials, and verified software. This is an individual contributor role where you'll take ownership of significant components of a mission-critical service, working with growing independence alongside senior engineers and architects to solve increasingly complex and ambiguous problems.
