40Role Number:
200557135The Darwin Runtime team in Core OS is looking for enthusiastic engineers interested in developing low-level system technologies for Apple's operating systems. Darwin is the UNIX-like foundation at the heart of all Apple's operating systems, stretching from the kernel up through low-level user components. The Darwin Runtime team is responsible for building the low-level user space runtime technologies like Grand Central Dispatch (GCD), inter-process communication systems, memory allocator, threading library, and concurrency and synchronization primitives. Other than being the foundation for iOS and macOS frameworks and applications, these technologies are deeply integrated into the Swift programming language to guarantee robust and high performant primitives built from the ground up. The ideal candidate should be self-motivated and effective in operating independently, with a desire to learn and develop technical leadership. Team members are welcome and encouraged to participate in design discussions, code reviews, and development across multiple technologies. Our environment fosters technical innovation, meaningful technology ownership, and a liberating amount of autonomy!DescriptionYou will be responsible for working on a range of technologies that form the foundation of Apple's operating systems. The work would include projects such as:Design and implement new features and APIs for Darwin Runtime technologies like GCD, XPC, pthread, and mallocAnalyze Apple's operating systems to understand the structure of the software and use that knowledge to make deep changes across the entire stackArchitect high-security environments to improve customer security and privacyWork with Swift language team to design and develop features to provide operating systems integrationAn engineer in the Darwin Runtime team would regularly:Participate in all phases of software development cycle: from problem definition and design, through implementation, testing, and debuggingDiagnose and resolve issues across different layers of the stackWork with cross functional teams to enable developer and product requirementsMinimum QualificationsPassion for low-level system technologiesFluency in the C programming languageExperience with UNIX-like systemsSystem design and architecture skillsStrong understanding of operating system fundamentals like threading, synchronization primitives, inter-process communication, scheduling, and virtual memoryExcellent collaborative skills, with the ability to work with a team to design system architecturePreferred QualificationsKnowledge of operating system implementation, hardware architecture and assembly programmingKnowledge of Swift or Objective-CSkilled at interface and/or API designExperience with lldb or gdbInvolvement in open source technologies and development communities such as Darwin, FreeBSD, Linux, etc.BS/MS in Computer Science or equivalent knowledge and experiencePay & BenefitsAt Apple, base pay is one part of our total compensation package and is determined within a range.
