We’re looking for an exceptional Senior Interaction Designer who can drive quality movement and interaction across Superhuman’s brand-in-product. We are looking for someone who not only understands AI motion tooling but equally understands how to develop the connection to the brand principles and feeling behind the movement.

You’ll develop Superhuman’s motion language — designing and delivering micro-interactions, UI transitions, product reveal moments, and brand animations that feel cohesive, intelligent, and distinctly Superhuman. And you’ll bring genuine, hands-on fluency as a part of your workflow.

Reporting to the Director of Design Foundations, you’ll partner closely with the Brand Experience team, product designers, engineers, and marketing. Your work will touch every product surface throughout the suite.

Define and evolve Superhuman’s motion design language — spanning UI micro-interactions, onboarding flows, feature introductions, loading states, and brand moments across product and marketing.

Design, prototype, and deliver high-fidelity micro-interactions and transitions that communicate state, guide attention, and make our product feel alive.

Actively use AI-powered motion tools — including generative video, creative AI and LLM-assisted workflows as a core part of how you concept, iterate, and produce.

Build and maintain motion guidelines, principles, and a shared library of reusable animation components that help other designers and engineers implement motion consistently.

Partner with engineering to ensure animations are implemented accurately and performantly in production, with a clear understanding of Lottie, CSS animations, and React-based animation libraries.

Explore speculative motion concepts that push forward what Superhuman’s product could feel like — using prototypes to communicate ideas before they’re built.

Mentor other designers on motion craft and help build a culture where animation is thoughtfully and consistently applied.

We want to see your best work that reflects both your range and your depth. Please share links to motion work featuring UI/product animation, as well as any brand, campaign, or experimental pieces. Include context for each: what was the problem, what was your role, and what were the constraints.
