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 iOS Engineer at WHOOP, you will be involved in the planning, design, development, validation, and maintenance of various features.

The WHOOP app continuously loads and processes streaming data from our proprietary MFi peripheral (WHOOP strap) and presents the data after processing to the user in a meaningful and impactful way.

Since this happens all day, the app is responsible for transporting large amounts of data between the strap and the backend server.

While that is happening, the app also 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 an interesting set of challenges unique to the WHOOP system.
