As part of the Core IO Networking & Sensors Architecture team, you will be working on the platform code that drives our operating systems on iPhones/iPads/Apple Watch/Mac. We deliver a unified solution to the entire company. Working on this team will redefine your understanding of cross-functional. We deliver daemons, frameworks, certification test suites, command line tools and even some bits of UI. And our code runs on everything. Programming languages we use on this team are C, Objective-C and Swift. You do not need to be an expert in all three to be successful. So long as you are well-versed in at least one of them, and are confident in your ability to learn.
