  • Experience building and shipping at least one app from scratch to production
  • Solid understanding of mobile performance, animations and app lifecycle
  • Ability to work independently in a startup environment where speed, ownership and adaptability are key

  • Experience with fitness, health or wellness apps
  • Familiarity with Apple HealthKit or Google Fit integrations
  • Strong eye for design and passion for building polished UI and user experiences

  • Be part of a high-growth fitness-tech startup shaping the future of fitness
