Role Number:200595572
Seeking a strong C, C++, Swift, or Obj-C developer for Apple's HTTP protocol implementation (HTTP/1.1, HTTP/2, HTTP/3) as well as URL and URI standards. The group is responsible for the client-side HTTP code that powers Safari and WebKit, iCloud, App Store, Music, and the vast majority of other Apple and 3rd party apps and services, on all of Apple's OSs (iOS, macOS, watchOS, tvOS, and visionOS). Besides networking, you are already proficient in — and if you're still learning as we all are, are encouraged to become fluent in — run-time performance optimization, multithreaded programming, cross-layer design, and many other concepts common to general software and OS development. Our developer API, URLSession, is implemented in the CFNetwork and Network frameworks in the Internet Frameworks & User Privacy org. We are also responsible for the Swift URL API (as well as preceding NSURL and CFURL API), implemented in Foundation framework and Swift open source libraries. These APIs have Swift and Objective-C interfaces, but are also implemented in C and C++. Peer groups, with which you may need to collaborate closely, include WebKit, and framework teams supporting AirDrop, Messages, FaceTime, and Swift.
