At WHOOP, we're on a mission to unlock human performance. WHOOP empowers users (Olympians, Professional Athletes, Fitness Enthusiasts, etc) to perform at a higher level through a deeper understanding of their bodies and daily lives. We are looking to add highly motivated skilled engineers to our team to help us scale and take our proven system to new heights. 
As a Senior Android Engineer at WHOOP, you will own the development of our Android community stack. The WHOOP app provides users with team leaderboards and other insights. This means the app is not only responsible for the transport of large amounts of data between the peripheral and our backend server, but also requires complex views, visualizations, and interfaces to give the user insights into the data in near-real time. The combination of these requirements presents an interesting set of challenges unique to the WHOOP system.
On the Gamification Team, you will work with your teammates to enable members to discover, socialize, and inspire like-minded athletes on our platform. You will help grow and retain the member base of WHOOP by owning high impact features that drive engagement with the platform. You will participate in the technical direction and influence features alongside product management, design, and members of the leadership team.
