OS Performance Tools Engineer - UI Hitch Diagnostics

The OS Performance Tools team is looking for a passionate and driven engineer to lead the development of hitch diagnostics and tooling to help Apple deliver the fluid, responsive user experiences our users deserve. This role focuses solving complex technical and logistical challenges with building low-overhead collection mechanisms as well as effective analysis tools for hitch diagnostics on Apple's platforms.

You will be working on challenging technical problems at the intersection of systems performance and user experience, collaborating extensively with teams across Apple that are involved in rendering content to the screen. This is an opportunity to have a significant impact on the smoothness of each interaction our customers have with their devices.

Description

In this role, you will own the technical vision and development of tools used for detection, diagnostics generation, and analysis of UI hitches in animations, scrolling, and other interactions across Apple's platforms.
