About Apple and the Role

Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. Join Apple, and help us leave the world better than we found it.

Apple’s Network Infrastructure is a critical foundation in delivering Apple’s services (such as iCloud, iTunes, Siri, Maps, Private Cloud Compute) to billions of customers and its employees. Apple’s Data Center Networking team is responsible for all aspects of the Network Infrastructure, from Operations to Architecture, deployed globally across Apple’s Data Centers and Edge locations. We are responsible for delivering a network that can match Apple’s scale, reliability, and security goals.

We work closely with Apple’s other Infrastructure organizations, Hardware, and Software Architecture teams to influence, build, and operate Apple’s Infrastructure. Our influences can range anywhere from Data Center Network Fabrics to a Hardware System Design. We listen to different perspectives, help surface innovative ideas, and drive decisions that move us forward.
