Making the world a healthier place by gamifying fitness. Liftoff is the Duolingo of fitness, empowering anyone to start and stay at the gym so they develop healthier, more powerful habits. You'll join the Product team and work closely with the Head of Product, collaborating with Engineering, Design, and Growth.

Design front-runs everything we build. The surfaces you make are what our experiments run on, what our retention depends on, and what over a million people open at the gym. We're hiring a Mobile UI/UX Designer to own app surfaces end-to-end: new flows, redesigns of what's already live, and the design system behind both.

UX is the priority. You'll diagnose and fix existing experiences, not only design current ones, and you'll back those calls with real user input. Mobile screen, flow, and component design UX evaluation and repair of live surfaces User interviews and feedback loops that drive design decisions Design system growth and consistency Graphic and visual assets, secondary to product design Flows that ship and hold up.

Existing UX measurably improved. User interviews and community signal feed design decisions on a regular cadence.

A design system that scales: consistent visual language, reusable components, fewer one-offs. Design mobile surfaces end-to-end Build screens and components that balance playful, game-like design with product clarity and usability Evaluate and fix existing UX Revamp and upgrade existing screens with sharper UX and fresh visuals Pull signal from community feedback, support threads, and product metrics Turn findings into specific design changes, then close the loop after they ship Own and expand the design system Maintain a consistent,



scalable visual language across the app Create graphic and visual assets (secondary) In-app graphics: splash screens, status cards, game-like items, collectibles Occasional graphics for landing pages and social Communicate animation intent clearly. We care most about ownership, judgment, and shipping.

Strong UX fundamentals. Auto Layout, Components, Variables, Prototyping Mobile-first design experience on shipped apps or game interfaces Hands-on user research experience. You've run interviews or usability tests and changed a design because of what you heard.

Evidence you've shipped something real: 3+ years in consumer mobile, strong industry experience with following portfolio, or a built product with real users.
