Debugger Qualification Engineer

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


Weekly Hours: 40
Role Number:200164501
The Debugger Technologies team at Apple is looking for an engineer to work on the delivery and testing of the LLDB debugger. LLDB is a core part of Apple's developer tools, used internally to debug Apple's software stack and externally by millions of developers. We are looking for a debugger engineer to join our efforts. 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 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 Python scripting for automation
  • Experience with build systems (CMake is a plus)
  • Passion for crafting software and tools
  • Strong communication and teamwork skills
  • Positive and respectful attitude in a diverse environment


In this position, you will be in charge of the LLDB debugger’s testing on the growing number of Apple platforms. You will work closely with the rest of the team to maintain and improve LLDB’s qualification matrix. You will develop new testing strategies to catch regressions before they affect our internal users. Internally, you will collaborate with other teams, including our kernel and runtime teams, to make sure their changes don’t impact the debugging experience negatively. Last but not least, you will also be in charge of the delivery of LLDB to our internal and external users, in close collaboration with the Swift and Clang teams. 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.
