Site Reliability Engineer, Enterprise Technology Services

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. The Insight team runs one of Apple's most critical Big Data ecosystems - a multi-petabyte, highly-available infrastructure that underpins manufacturing operations for every Apple product, globally. Every iPhone, iPad, and Mac has touched our systems. We are establishing a new EMEA operational team in Cork, not only as an extension of our US/India/China operations, but also a team with its own identity, perspective, and contribution to how Insight runs at global scale. This is a new regional team being built from the ground up, and the people who join early will help shape what it becomes. We are looking for a Site Reliability Engineer who has operated in the European high-tech landscape, who brings the rigor and perspective that comes from that environment, and who wants to shape the practices of a new team. As one of the first few SREs in Cork, you will have real influence over how this team works, what it builds, and how it contributes to Apple's manufacturing infrastructure worldwide.
