• You will join the Mobile Platform team and work within a group focused on foundational mobile capabilities. • Collaborate with other iOS and Android engineers, as well as product and design partners, to raise the quality of motion and interaction across the app. • Design and build animations, transitions, and interactive UI components in SwiftUI, Lottie, and Rive. • Work closely with designers to explore ideas quickly and turn the best ones into production-ready patterns. • Help teams evaluate motion concepts, understand trade-offs, and use animation to improve clarity and engagement. • Bring other engineers along as a key part of the role. • Document patterns, create examples, pair with engineers when needed, and help the organization understand when and how to use motion responsibly. • Build systems that enable product teams to ship polished interactions without relying on bespoke implementations.
