Senior Product UI/UX Designer

About the role

You'll be the first dedicated Product UI/UX Designer at BEAT81, a fitness-tech startup, owning design across their member app, coach tools, and in-workout experiences. This role uniquely combines traditional product design with designing for high-intensity moments when users are under physical and cognitive load during workouts.

What you'll do

• Own Product Design across BEAT81's member app, coach tools, and in-workout experiences
• Build and maintain design systems that create consistency across the product suite
• Design real-time workout interfaces translating complex data (heart rate, power, cadence) into intuitive visuals
• Create in-class feedback and progress tracking experiences
• Work directly with CEO/CPO, Product Managers, and engineering squads as the first dedicated designer
• Design iteratively, prototype rapidly, test in live environments, and iterate based on observed behavior
• Balance long-term system-thinking with hands-on execution and contribute to Product strategy

What you'll need

• 5+ years of Product Design experience with demonstrable work on real-time, high-cognitive-load interfaces
• Regular command of AI tools to accelerate workflow for concept generation, prototyping, and design exploration
• Strong motion design skills thinking in states, transitions, and feedback loops beyond static screens
• Fluency in Figma, prototyping tools (Principle, ProtoPie), and front-end understanding for team collaboration
• Ability to articulate design decisions with user psychology and design best practices
• Bias toward testing over debating with comfort in ambiguity and ownership
• Located in Berlin

Nice to have

• Background in game design, interaction design for sports/fitness, or immersive experience design
• Experience with spatial/environmental design (stadium displays, retail experiences, live events)

What they offer

• Unlimited BEAT81 workouts for you and one other person plus John Reed Berlin membership
• Professional development budget for courses, workshops, and certifications
• Flexible working hours for work-life balance
• 12% discount on massage bookings and quarterly health initiatives
• Free drinks, fresh fruit, coffee, and office perks plus dog-friendly workplace
