Senior Software Engineer, watchOS System Spaces

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.

Description

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.

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.
