Compiler Frontend Engineer

full-timePosted: Oct 15, 2025

Job Description

Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you'll do more than join something — you’ll add something. We are seeking brilliant engineers passionate about compiler technologies and programming language innovation to join the C Languages and Libraries team. In this role, you’ll advance the Clang compiler and pioneer seamless interoperability between C++ and Swift. Clang and Swift compilers are at the heart of Apple’s developer tools and Xcode, used across Apple to build everything from operating systems to apps, as well as by millions of developers for their daily development work. You’ll have the rare opportunity to enhance the development experience of countless developers worldwide, and to collaborate with thriving LLVM and Swift communities to shape the future of programming on Apple platforms. The team's work is regularly showcased at Apple’s WWDC and in LLVM Developer Meeting. Join a supportive, tight-knit team within an encouraging, growth-focused workplace culture. In this role, you will design and implement compiler and language features in the Clang compiler to advance the stability, performance and security of C/C++/Objective-C software running on Apple platforms. Additionally, you will develop innovative Swift compiler features to advance seamless interoperability between Swift and C++ languages. You will have the opportunity to drive all aspects of feature development from conception to completion, including planning, implementation, deployment, and communication. Working collaboratively with teams across Apple, you will identify compiler solutions that address their specific requirements and enable successful adoption of new compiler features. You will engage with and support the large, diverse user base of Clang and Swift/C++ interoperability both within Apple and externally. You will also be an active contributor to the llvm.org(http://llvm.org/) and Swift(Swift.org) open source projects and collaborate with the open source community to advance these technologies. You'll join a supportive team that provides technical guidance, software architectural reviews, and mentorship within an encouraging, growth-focused workplace culture. We value creativity, communication skills, and integrity.
