Swift Platform Experience UIKit Frameworks Engineer

Summary

Do you want to help define the future of app development on Apple platforms? Join the UIKit team and help shape the APIs and components used by millions of apps across iOS, iPadOS, and beyond.

When you work here, you don’t just ship features — you influence how developers around the world build and experience apps. We’re a small, passionate team driving big impact across the entire Apple ecosystem.

Description

UIKit powers nearly every interface you see on iPhone and iPad — from touch and event handling to animation, text, layout, and high-level components like UICollectionView, UIHostingConfiguration, and UIGestureRecognizer.

As part of the UIKit team, you’ll collaborate closely with Human Interface designers and partner frameworks to prototype, refine, and deliver the next generation of UI technologies. You’ll work side by side with internal teams to create APIs that inspire developers and power incredible experiences.

If you’re motivated by clean architecture, thoughtful design, and making software that millions depend on every day - we'd love to hear from you.
