At WHOOP, we're on a mission to unlock human performance. WHOOP empowers its members to perform at a higher level through a deeper understanding of their bodies and daily lives.
The Senior Android Engineer will be involved in the planning, design, development, validation, and maintenance of various features of the WHOOP application. The WHOOP application continuously loads and processes streaming data from our proprietary Bluetooth peripheral (WHOOP Strap) and presents the data after processing to the user in a meaningful and impactful way. Since this happens all day, the
application is responsible for transporting large amounts of data between the strap and the backend server. The application requires complex views, visualizations, interfaces, and interactions to give the user insights into the data in near-real time. The combination of these requirements presents a set of challenges unique to the WHOOP system that the Senior Android Engineer will be responsible for solving.
