Weekly Hours: 40
Role Number:200597019
Apple’s Developer Security Tools team builds new programming language features and compiler technologies to eliminate entire classes of security vulnerabilities, harden existing codebases, and extend the reach of memory-safe languages into security-critical environments. We partner closely with the security and operating systems teams at Apple to deploy these language features and tools to improve the security and stability of Apple's platforms. The team actively contributes to the LLVM and Swift open source projects. We are looking for a generalist engineer with experience in tools (such as any of compilers, linkers, or program analysis tools) and a passion for security to help lead the technical planning, design, implementation, and rollout of new system-wide tool-based security protections. This role will involve developing compiler- and OS-assisted security features, mentoring engineers, and partnering with operating system and security teams to improve the security and reliability of software in the Apple ecosystem. We value communication skills, integrity, creativity, and aspire to build diverse, balanced and dynamic teams.

Description

In this role, your primary responsibility will be to develop new tool-based security features to secure software running on over 2 billion devices. You will make contributions across the tools stack (compilers, linkers, debuggers, programming languages, ISA design, etc.) and operating systems codebases (such kernels, firmwares, loaders, and system allocators, etc.) Your home base will be developer tools, but you will make contributions across the OS stack. This team collaborates extremely closely with operating systems, security, and hardware engineers to improve the security and stability of C, C++, Objective-C, and Swift codebases in Apple’s platform and ecosystem. The team actively participates in the Clang/LLVM and Swift open source communities. You will: - Help develop and execute on a technical roadmap to build compiler and language-based security protections to continually improve the security of Apple’s operating system software stack, including user space, kernel, and firmware environments - Work with cross-functional teams to design, plan, and deliver high-quality software features for our tools and operating systems - Strengthen the team by mentoring junior engineers - Grow strong connections to the Clang/LLVM and Swift communities and represent Apple in open source - Develop new compiler security features by driving feature planning, design, implementation and roll out strategy - You will foster collaboration with security, operating systems, and hardware teams as well as teams across Apple to help formulate priorities and set goals for the team. Your work will directly improve the development experience for millions of developers across the world Here you’ll find that we: - Have a supportive and tight-knit team - Provide mentorship on technical as well as social skills - Have an encouraging and growth-focused workplace culture If this sounds of interest to you, we'd love to hear from you!
