Senior Software Engineer, watchOS System Spaces

Cupertino, California, United StatesSenior$150,400 - $277,6006+ years

The watchOS System Spaces group is seeking a new colleague to help us shape the future of Apple Watch. As a senior software engineer on the team, you will work on the systems behind the always-running watchOS experience, including notifications and alerts. You'll collaborate with talented and creative colleagues to meet ambitious goals in an environment that values curiosity, craft, and growth. Your work will be experienced by millions of Apple Watch users every day.

This is a systems role at the center of the watchOS experience. The software in this group runs continuously and sits beneath most of what a user does on their watch, from notifications to app launch, and it works within a small power and memory budget. Designing well in that environment means treating reliability, power, and memory as part of a feature rather than as follow-up work, and being willing to follow a problem into code your team does not own. Systems experience transfers well here, whatever platform you have built on. The engineers who do well on this team enjoy working inside constraints rather than around them. Curious and resourceful people who take an expansive view of their role will thrive in this multidisciplinary environment, where you'll have the opportunity to collaborate with experts across Apple.

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.

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.

Experience with low-level software on constrained hardware.
Experience with multi-device or distributed systems.
Familiarity with operating system internals, including process lifecycle and networking.
Experience improving and expanding on existing complex projects.
Comfort navigating ambiguity and iterating toward solutions in a fast-moving environment.
Thoughtful use of GenAI coding tools to accelerate development without compromising clarity or craft.
Genuine enthusiasm for wearable technology, and for the work of defining what an Apple Watch can be.
