Sr. Profiling Tools Engineer - Xcode

With every new technology, framework, or product, there's a need for tools that can expose important underlying system behaviors. As a result, a strong passion for learning is essential. You'll need to work effectively with Apple teams of different engineering disciplines, anticipate problems early, and communicate ideas clearly. An ideal candidate will be able to drive development projects independently, collaborating with other teams to solve tough engineering challenges, and iteratively developing and integrating solutions to complex problems. Explore our work Curious about what the Profiling Tools team ships? The best way to understand what this team builds is to watch what we've shipped at WWDC: From helping developers debug and profile agentic app experiences and find and fix performance issues in Metal games, to enabling them to profile, fix, and verify app responsiveness and optimize SwiftUI and CPU performance with Instruments — these sessions reflect the kind of engineering challenges you'd take on.
