You’ll work on Compiler tooling for Swift, Clang and LLDB debugger on all Apple platforms.You will make decisions about how to architect engineering, and integration workflows, considering both short- and long-term goals. Once solutions are identified, you’ll design, implement, and deploy automation and workflow changes for building, testing, and deploying the toolchain. You’ll engage with the open source LLVM (https://llvm.org/) and Swift (https://swift.org/) communities, reducing downstream overhead by driving improvements to open source infrastructure, tooling, and engineering workflows at https://github.com/llvm and https://github.com/apple.You will improve the efficiency of open source engineering workflows and scale compiler qualification infrastructure to support Swift and Clang compilers. You will find opportunities to innovate, and create tools and processes to reduce or define away problems. As an example, you might work on improving the pull request testing process for open source changes in GitHub by making it more efficient and adding testing features. In addition to finding technical solutions to problems, you will be involved with coordinating between multiple teams within Apple and the open source community using clear, consistent and timely communication.
