Apple’s dynamic program analysis tools help millions of developers inside and outside of Apple find, fix, and prevent security and stability bugs. We are looking for a senior engineer with a strong background in systems-level developer tooling to lead the technical planning, design, and implementation of dynamic bug-finding tools. This role will involve developing compiler- and OS-assisted program analysis features, mentoring engineers, and partnering with operating system and security teams to improve the security and reliability of software in the Apple ecosystem. We value communication skills, integrity, and creativity, and aspire to build diverse, balanced and dynamic teams.
