C++ Standard Library Performance Engineer

Job Description:

The C++ Language team at Apple is looking for a software engineer to develop and enhance Apple's C++ standard library ("Libc++") that ships on Apple's platforms, with a main focus on performance. Libc++ is a core part of Apple's developer tools and Xcode IDE, used internally to build Apple's software stack and externally by millions of developers. The position provides the opportunity to learn and make changes to the Apple C++ compiler ("Clang"). A lot of the team's work happens in the LLVM open source community and gets presented at LLVM Developer Meetings and other conferences.
In this position, you will contribute to the evolution and development of Libc++ and Clang with a focus on improving the performance of Apple platforms. You will drive the implementation of new C++ features that boost performance, evaluate and optimize existing components of the library. You will work with LLVM compiler engineers, hardware engineers and operating system engineers across Apple to help shape the future of our platform, languages and tools. You will have the scope to understand and improve the interplay between the C++ standard library, the compiler, and the hardware to deliver the best C++ performance for Apple platforms. You will also work with the greater C++ community and contribute to the LLVM (http://llvm.org/) open source project, as well as the language communities such as ISO WG21. Here you'll find that we have a supportive and tight-knit team that provides technical guidance, software architectural review, and mentorship. We have an encouraging and growth-focused workplace culture.
