As a Software Engineer on the Darwin Runtime team in Core OS at Apple, you will work on developing low-level runtime technologies such as Grand Central Dispatch (GCD), secure inter-process communication systems, memory allocator, and threading library. Your responsibilities include designing and implementing new features for these foundational technologies, optimizing performance and memory usage, and participating in all phases of the software development cycle from design to debugging. You will collaborate closely with kernel engineers, security architects, and framework developers to deliver high-performance runtime libraries that ensure secure communication and efficient memory management across various execution environments. The ideal candidate should have a strong background in low-level systems programming, fluency in C, experience with UNIX-like systems, and knowledge of operating system fundamentals like threading, synchronization primitives, inter-process communication, scheduling, and virtual memory. Additional skills in compiler design, capability-based security models, Swift or Objective-C, and debugging tools like lldb are highly valued.
Design and implement new features for Darwin Runtime technologies like GCD, XPC, pthread, and malloc.
Develop high-performance runtime libraries for secure communication and memory management across execution environments.
Optimize code generation and runtime performance to meet strict low-level system requirements.
Participate in all phases of the software development cycle from design through debugging.
Diagnose and resolve issues across different layers of the stack independently.
