Our Mission: 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.
We’re a mission-driven team that moves fast, owns the details, and does the work. We’re fully bootstrapped, profitable, and built from zero to $10M+ ARR in under three years.
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.
Your core focus areas:
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. PM ideas become mockups, then production surfaces, with nothing lost in between.
Existing UX measurably improved. Audits turn into fixes, and the fixes move the metric.
A running feedback loop. 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.
Clear communication on what you designed, why, and what it did.
Design mobile surfaces end-to-end
Turn ideas and feature briefs into flows, wireframes, and high-fidelity mockups in Figma
Build screens and components that balance playful, game-like design with product clarity and usability
Think in hierarchy, flow, accessibility, cognitive load, and micro-interactions
Evaluate and fix existing UX
Audit live app surfaces and find where users stall, drop, or get confused
Revamp and upgrade existing screens with sharper UX and fresh visuals
Prioritize fixes by impact
Run the feedback loop
Plan and run user interviews and usability sessions
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
Build reusable components that work across screen sizes
Create graphic and visual assets (secondary)
In-app graphics: splash screens, status cards, game-like items, collectibles
Vector character work for our mascot Jymbo, including new poses and outfits as features need them
Occasional graphics for landing pages and social
Communicate animation intent clearly. Storyboard or spec the simple motion your designs need, and execute it in Rive when it's straightforward.
We don't expect you to check every box. We care most about ownership, judgment, and shipping.
Strong UX fundamentals. You can explain why a layout works, not just build it.
Deep Figma fluency: 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
Clear written communication. You can document decisions, write specs, and share learnings.
Comfort in a startup environment: short feedback loops, big ownership, no red tape
Video game UI/UX background or a real passion for it
Illustration experience and a sharp sense of visual humor
Experience maintaining and evolving a design system
Shipped in health, wellness, social, or gaming
Created shareable or viral graphics for apps or games
Can execute simple animations yourself. Rive for stateful animations, Adobe After Effects + Lottie for motion graphics and VFX.
Can implement your own designs (React Native / Expo, Tailwind). Useful, though not part of the core job.
Sustained depth in a craft, sport, or community outside of work
You don't need prior experience with every tool, but you should be comfortable working with this stack.
Design: Figma (primary), Adobe After Effects + Lottie, Rive
App: React Native (Expo), Typescript
Backend: Supabase, Vercel, tRPC, Node.js
Monetization: RevenueCat, Superwall
Experimentation / Analytics: Statsig
Autonomy and Ownership: you are in charge of your time at Liftoff. Decide what you want to do, align with leadership, and go for it.
Top-of-the-Market Cash & Equity Compensation: we pay for high performers.
A World-Class Team: low-ego, high standards, and real ownership.
Hiring Manager Screening
Take-Home Challenge (app screen design)
Design Deep Dive (portfolio walkthrough plus a live UX critique of an existing Liftoff surface)
Work week trial (paid, simulating real work environment)
Competitive salary (based on level and scope)
Company-paid lunch every day (if you’re in office)
Lifetime Liftoff Pro membership
Liftoff is an equal opportunity employer. We hire and grow talent based on strengths, potential, and performance, and we are committed to building an inclusive environment where everyone can do their best work.
Your portfolio showing end-to-end product design (mobile, web, or games). We want to see decisions and trade-offs, not only final artifacts.
Your resume and LinkedIn/X profile
Any character, mascot, or in-app visual work you've made
(Optional) Any motion work: Rive files, After Effects clips, or motion mockups
