Job description

UI Motion Designer

Location: Remote (U.S.-based)

Employment Type: Part-Time (~20 hours/week,

Team: Product Design

About the Role

Our client is looking for a UI Motion Designer to help shape the dynamic visual language and interaction behaviors of our flagship app. In this role, you will define how motion breathes life into our core product features—crafting intuitive transitions, micro-interactions, and state changes that elevate the member experience.

You will work closely with product designers, design systems leads, and mobile engineers to design, prototype, and implement fluid, high-fidelity UI animations. If your style leans modern, editorial, and polished, and you thrive on turning static designs into elegant, interactive moments, we’d love to connect.

What You’ll Do

• Design In-App Motion: Create nuanced, functional micro-interactions, gestures, transitions, and state changes specifically tailored for mobile UI/product flows.
• Bridge Design and Engineering: Partner directly with iOS, Android, and front-end engineers to ensure motion designs are feasible, performant, and implemented true to spec.
• Iterate Collaboratively: Navigate multiple feedback and testing loops alongside engineering teams to fine-tune timing, curves, and responsiveness across varied device performance profiles.
• Uphold an Editorial Aesthetic: Champion a modern, restrained, and purposeful motion style that feels seamless and deliberate rather than decorative or distracting.
• Produce Production Assets: Package, spec, and deliver motion assets and parameters using modern runtime motion tools and design handoff specifications.

What We’re Looking For

• 3–5+ years of motion design experience, with a primary emphasis on mobile UI and in-app interaction design.
• A portfolio demonstrating UI motion work that showcases an editorial, modern, and clean aesthetic applied to live or prototyped mobile application experiences.
• Working knowledge of Figma basics to navigate design systems, pull components, and integrate into product design workflows.
• Deep understanding of interaction patterns: Familiarity with touch/swipe mechanics, spatial consistency, easing curves, and mobile UI constraints.
• Technical handoff expertise: Proven comfort collaborating with engineers through technical implementation, edge-case troubleshooting, and visual QA.
• U.S. residency/authorization: Must be based within the United States.

Nice-to-Haves

• Hands-on experience with Rive for runtime, interactive vector graphics and state machines (strongly preferred).
• Experience with Lottie, After Effects, or prototyping tools like ProtoPie.
• Supplementary experience in marketing or brand motion video.
