The Challenge We’re Solving

• Deep understanding of mobile design patterns, gestures, and platform conventions (iOS/Android)
• Ability to translate user insights and data into clear, actionable design decisions
• Strong grasp of user flows, onboarding, and retention-driving UX patterns
• Comfortable working in a fast-moving environment where designs go from concept to shipped quickly
• Strong communication skills — ability to defend design decisions in relation to UX/UI design principles

Bonus Points:

• Experience designing for health, wellness, fitness, or lifestyle apps
• Familiarity with habit-forming design and behavioral psychology principles
• Experience building and maintaining a scalable design system from scratch
• Background in user research — you’ve run interviews, usability tests, or surveys
• Basic understanding of front-end development — you know what’s feasible to build
• Experience working directly with engineers using tools like Zeplin or Storybook
• Passion for health and fitness — you understand this world because you live it

Why Join MenuFit?

Direct Impact — You’ll work closely with leadership and see your designs reach over a million people across our platforms

Creative Autonomy — We hire talented people and trust them

Strong Team — Join a 20-person team of driven, creative people who care deeply about the work

Growth — As we scale, this role scales with us. We want this to be a long-term home for the right person

Compensation & Benefits

Base Salary: $60– $75

Equity Opportunity: Grow alongside us!
