About The Position

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.

DESCRIPTION

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.

Requirements

• 3+ years macOS or iOS development experience
• Excellent verbal and written communication skills
• Expertise in C or C++, proficiency in Swift and/or Objective-C

• Detail-oriented code review skills, reasoning through edge cases and security implications

Nice To Haves

• Problem solving and debugging skills with lldb, gdb, or other interactive tools
• Experience using AI technologies to assist in authoring, reviewing, and debugging code
• Skills in reverse engineering, exploit analysis, fuzzing, binary analysis tools helpful
• Familiarity with macOS internals, mach APIs, sandboxing, and other security subsystems
• History of designing, implementing, or improving development tools
• Experience in computer science or a related field commensurate with a 4-year degree
