Software Engineer II (Full Stack, Platform)

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level and live longer through a deeper understanding of their bodies and daily lives. Protecting our members’ data and ensuring our systems scale securely and reliably is core to this mission.

We are looking for a Software Engineer II (Full Stack Web) to join our Client Platform team, focused on Design Systems and Translations. In this role, you’ll design and build shared frontend and backend systems that enable WHOOP to deliver consistent, high-quality, and globally accessible experiences across web and mobile surfaces. You’ll work across the stack — from frontend component libraries to backend localization services — while also contributing to the infrastructure and tooling that power design systems and internationalization at scale.

This role is a great fit for an engineer who enjoys working across web technologies while also tackling platform challenges like design system consistency, localization workflows, and right-to-left (RTL) support. You will play a key role in enabling global expansion by making it easy for teams to build localized, accessible, and visually consistent experiences.
