Seeking a strong C or C++ developer with a background in networking, with a primary responsibility for HTTP authentication, security, enterprise, and proxy support. You will be joining the CFNetwork team, a small band of HTTP/1.1, HTTP/2, OS-level and networking experts working in Apple Park in the SW Engineering org. We are responsible for NSURLSession, NSURLConnection, and other Swift and Objective-C APIs. These APIs are a critical part of the networking stack used by Safari/WebKit, iCloud services (including Photos, Drive, and Backup), Messages, App Store, iTunes, Siri, Mail, Calendar, Apple Pay, many more first party, and the vast majority of 3rd party apps. You should be comfortable and excited to work on existing library code critical to the customer experience, as well as designing and implementing new features. The CFNetwork team supports all of Apple's main software platforms — iOS, macOS, watchOS, and tvOS. You will interface with lower-level networking APIs, application-layer features, other system-level frameworks and APIs, and the engineering experts responsible for all of these components.

  • Familiarity with any of Cocoa, Swift, Objective-C, iOS/macOS, or cross-platform development
  • In-depth knowledge of one or more areas in networking — the team will have expertise in the areas you will be responsible for, but you should be able to learn quickly and provide keen insight, while both driving yourself independently and collaborating well within and outside the team
  • Strong understanding of one or more elements of HTTP networking (protocol-level details, cookies, authentication, cache, security, and performance), or ability to come up to speed before interview
  • Excellent communication and collaboration skills
