Responsibilities

  • Design, implement, and ship new capabilities in the watchOS system experience, and shape the interfaces other teams build on.
  • Own the reliability of software that spans process and device boundaries, and root-cause failures from logs and traces on shipping hardware.
  • Improve the architecture of long-lived systems that many teams depend on: state management, concurrency, and inter-process interfaces.

  • Work with engineers, designers, and product partners across Apple to keep watchOS coherent with the rest of our platforms.
  • Advocate for the unique needs and opportunities of the Apple Watch platform in cross-functional forums.

Qualifications

  • 6+ years of software development experience.

  • Experience building or maintaining systems software: daemons and services, inter-process communication, concurrency, or embedded environments.
  • Experience diagnosing failures that cross process or device boundaries.
  • Proficiency with Swift and Objective-C.
  • Ability to work collaboratively and explain complex ideas clearly.
