Sr. Profiling Tools Engineer Xcode

The Profiling Tools team is looking for engineers with a passion for optimization to lead new capabilities end-to-end: what gets built how it works and what ships to millions of developers across iOS macOS tvOS and watchOS. Core responsibilities include improving runtime data collection analysis and visualization in Apples Developer Tools Developer Tools group provides the foundation that developers worldwide rely on to design write build debug profile and deploy software. Its a uniquely rewarding area where engineers own not just the implementation but the direction and where the people using what you build are other developers turning ambitious ideas into shipped Profiling Tools team primarily focuses on the debugging and profiling aspects of the development process using runtime analysis techniques to instrument and introspect software to understand and improve it. The team is responsible for tools such as Instruments xctrace and on-device components performing low-level data capture. Tools for analyzing app behavior improving responsiveness and minimizing power/memory consumption are critical to making great user experiences across Apples platforms.

With every new technology framework or product theres a need for tools that can expose important underlying system behaviors. As a result a strong passion for learning is essential. Youll 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 our worknCurious about what the Profiling Tools team ships The best way to understand what this team builds is to watch what weve 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 youd take 003ca hrefhttps:// recent Instruments sessions on the Apple Developer portalu003c/au003e
