Lead React Native Engineer (Barcelona or Canada, Hybrid)

About Hevy

Hevy is a free weight lifting workout tracker that lets athletes intuitively log their workouts, track progress with insightful analytics, and be part of a growing community of gym athletes.​

Our journey began in 2019. We were not satisfied with the existing workout trackers on the market, so we decided to build a more complete platform that allowed users to interact with their friends. Since then, we’ve been building Hevy thanks to the amazing community.

Our mission is to make humanity stronger by providing gym athletes the tools to become more successful at reaching their fitness goals.
