About the role

Senior software engineer role focused on the system spaces behind the always-running watchOS experience, including notifications and alerts. Design, implement, and ship new capabilities in the watchOS system experience, and collaborate across Apple to keep watchOS coherent with other platforms. Emphasis on reliability, power, memory, and inter-process interfaces within constrained hardware.

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.
  • Profile and optimize for the constraints unique to Apple Watch: latency, memory footprint, and power cost.
  • 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.
  • Solid computer science fundamentals; a specific degree or concentration is not required.
  • 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.
