At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives and empowers members with the insights to live a longer healthier life. As an SDET II, you will own the design and implementation of automated testing solutions across features and services. You will play a key role in improving test frameworks, increasing system reliability, and driving quality best practices across the team. This role is suited for engineers who can work independently, contribute to system-level quality improvements, and influence testing strategy. You’ll tackle hard testing problems, eliminate flakiness, influence architecture for testability, and raise the quality bar across teams. If you love writing real code, thinking in systems, and instilling quality as a shared principle —this role is for you.
