Memory Tools Engineer

Cupertino, California, United States Software and Services

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, watch

OS, and vision

OS. 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.

We’re looking for developers who are passionate about making software better! Core interests should include areas such as profiling, optimization, reverse engineering, debugging, security, graph theory, and data visualization. You should have an interest in all levels of the system with the ability to connect OS concepts like virtual memory with language-level tools such as runtime reflection and Swift Concurrency. With every new technology, framework, or product Apple releases there’s a need for tools to help expose and explain important system behaviors.

As a result, it’s key that you have a strong passion for learning! You’ll need to work effectively with Apple teams of different engineering disciplines, anticipate problems early, and communicate ideas clearly. You should be able to drive development projects independently, collaborating with other teams to innovate in solving engineering challenges, and iteratively develop solutions to novel and complex problems.
