Compiler Engineer

Santa Clara Valley (Cupertino), California, United States
Software and Services


Weekly Hours: 40
Role Number:200191609
The Debugger Compiler Integration team at Apple is looking for an engineer to work on the debug info support in LLVM, Clang and the Swift compiler. Our team works at the intersection of compilers and debuggers and maintains both the debugger support in all of Apple’s compilers as well as the language support in the LLDB debugger. LLDB is a core part of our developer tools, used internally to debug Apple's software stack and externally by millions of developers. Our team works to deliver reliable tools for all developers working on our platforms. We strive to build a diverse, balanced and dynamic environment! You will join a team of motivated engineers who build first-class debugging tools. We hire people at Apple to do the greatest work of their lives and revolutionize the state of the art in their field. As the saying goes, “Debugging is twice as hard as writing the code in the first place”. Your work on our team will help countless developers be more productive and ship best in class apps for the Apple platforms, current and to come. Far more than any specific experience or skill, we are looking for engineers who want to build great software, learn and develop their skills, and ultimately enable others to develop amazing applications.

Key Qualifications

  • Proficiency in C++ development
  • Passion for crafting software and tools
  • Strong communication and teamwork skills
  • Positive and respectful attitude in a diverse environment


In this position, you will work closely with the LLVM, Clang, and Swift compiler teams to improve the debugging experience. Most of your work will be open source, on ( and GitHub where you’ll collaborate with the LLVM and Swift communities to turn LLVM into the most accurate compiler when it comes to debug info quality. At Apple you will work closely with the teams around the company including, but not limited to, the Xcode, LLDB, compiler and build system teams. Your contributions will range from improving debug info quality to designing more efficient debug info storage formats that take advantage of Apple’s build systems. You’ll join a team based in Cupertino, California. You also will work closely with the larger developer tools organization colocated with us. Our team has a wide range of experience. New team members quickly get to own a part of the debugger and develop independence in their work. We will consider non-US applicants and are open to exploring visa options, provide relocation assistance, and offer excellent benefits.

Education & Experience

Bachelor’s degree or equivalent experience in computer science or a related field.
