Memory Tools Engineer
Apple's Memory Tools team is looking for developers with a passion for memory and resource optimization to enhance, adapt, and innovate in creating tools for the next generation of software and hardware on Apple's platforms. Memory is an important and limited shared resource, making intelligent, developer-friendly tools critical for identifying optimization opportunities. Core responsibilities include working with Apple performance optimization engineers, Swift and Objective-C runtime teams, and frameworks teams to introspect memory usage across Apple's ecosystem.
This role is within Apple's Xcode group, making tools that allow dreamers, makers, and shapers to design, write, build, debug, profile, and deploy software for all Apple platforms - macOS, iOS, iPadOS, tvOS, watchOS, and visionOS. Tools development is a uniquely rewarding area as the software's users are other developers, making it an opportunity to influence and improve the productivity of developers all across the world who make life-changing ideas a reality.
The Memory Tools team primarily focuses on creating profiling and optimization tools, using runtime analysis techniques to instrument and introspect software to understand and improve it. The team is responsible for command-line tools like leaks, heap, vmmap, sample, atos, symbols, symbolication services and frameworks, Xcode's Memory Graph Debugger, and runtime libraries that improve the built-in debugging experience on Apple's platforms. These tools and services for process analysis are used on over a billion devices and by developers worldwide who make life-changing ideas a reality.
