As a part of this team, you will be helping to develop the Swift compiler and associated runtime. You will work alongside experienced compiler engineers to implement high-level language analysis, new performance optimizations, improved code generation, or finding new and better ways to test and verify the correctness of a complex and critical codebase. You’ll be working primarily in C++, and the majority of your work will go directly into our github.com/swiftlang repositories, where it will be visible to the entire world.
