We're looking for a skilled UI/Frontend Developer to join our team and help build beautiful, performant, and accessible web experiences. You'll play a key role in shaping the interface of a web-based mobile application built for elite, professional cyclists - helping them prepare for the most challenging rides in the world.

• Ensure accessibility and cross-browser compatibility across a range of mobile and desktop environments
• Collaborate with designers to develop and maintain a cohesive UI component library
• Work closely with backend engineers to integrate Garmin fitness data and physiology model outputs into dynamic, real-time displays
• Write well-documented, reusable code and participate in code reviews
• Debug and resolve frontend issues across browsers and devices
