Apple • Boulder, CO

About The Position

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.

Requirements

• 6+ years of software development experience.
• Solid computer science fundamentals.
• 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.

Nice To Haves

• 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.

Responsibilities

• Work on the systems behind the always-running watchOS experience, including notifications and alerts.
• Collaborate with talented and creative colleagues to meet ambitious goals.
• Treat reliability, power, and memory as part of a feature rather than as follow-up work.
• Follow a problem into code your team does not own.
• Work inside constraints rather than around them.
• Collaborate with experts across Apple.
