Overview In this role you lead mechanical design and validation for WHOOP's flagship wearables, steering subsystems from concept to mass production. You collaborate across engineering, manufacturing, supply chain, and QA to deliver robust, cost-effective improvements driven by user feedback and business needs. You own validation strategies, DOE, and root-cause investigations, while mentoring junior engineers. Expect travel to partner sites and a fast-paced environment focused on high-quality hardware at scale.
