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 new 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

Bonus Attributes
Video game UI/UX background or a real passion for it
