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. As an Engineering Manager on the Client Platform team, you will lead a team responsible for building and scaling the systems that enable WHOOP to deliver a seamless, high-quality multilingual experience across mobile, web, and backend services. You will also be responsible for overhauling our Design Systems across mobile and web properties. This includes owning the infrastructure, tooling, and workflows that power localization, internationalization (i18n), and right-to-left (RTL) support, as well as consistent design patterns across our entire brand experience, expanding WHOOP’s reach and brand presence. You will operate at the intersection of platform engineering, product experience, and global expansion, partnering closely with Product, Design, Marketing, and external vendors to ensure projects are delivered accurately, efficiently, and at scale. This role is highly execution-focused, with an emphasis on building reliable systems, improving developer workflows, and enabling design consistency and rapid addition of new languages while navigating tradeoffs like vendor vs. in-house solutions.
