• Collaborate on and lead motion design across the product: define principles, patterns, and guidelines for interaction and UI motion. • Design high-quality microinteractions (transitions, state changes, loading/empty states, feedback, onboarding moments) that improve usability and delight. • Prototype early and often using motion-forward tools to explore interaction models and validate concepts quickly. • Partner deeply with engineers to ensure motion is implemented accurately, efficiently, and accessibly; provide specs and support QA. • Create reusable motion components and contribute to the design system (tokens, curves/easing, durations, choreography rules). • Improve product comprehension with motion that communicates hierarchy, cause/effect, and status (errors, success, progress, latency). • Use research and data to evaluate motion effectiveness (comprehension, conversion, time-to-complete, error reduction). • Mentor designers and up-level motion craft across the team via reviews, critiques, and workshops. • Collaborate with Brand/Marketing when needed to ensure motion feels cohesive across product and storytelling surfaces.
