What the job involves
- 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
- Design, build, and maintain full stack systems that power WHOOP’s design system and translation infrastructure
- Develop and maintain reusable frontend components and shared libraries using modern frameworks (React/TypeScript)
- Implement and improve internationalization (i18n) support, including right-to-left (RTL) layouts and bidirectional text handling
- Partner with Design to build and scale a unified design system across web and mobile platforms
- Build and maintain backend services and APIs that support translation workflows, content delivery, and localization pipelines
- Ensure UI components are flexible, accessible, and adaptable to different languages, screen sizes, and regions
- Improve and maintain build and CI/CD systems (CircleCI, GitHub Actions) to support fast and reliable delivery
- Collaborate cross-functionally with Product, Design, Platform, and Localization teams to deliver scalable solutions
- Participate in code reviews and contribute to best practices around frontend architecture, localization, and design systems
Our take
WHOOP develops wearable health-tracking devices designed to help athletes optimise their performance. Its technology continuously monitors recovery, sleep, and training hours to fine-tune both individual and team performance. Unlike competitors that primarily track exercise data, WHOOP's holistic approach includes metrics like heart rate variability, which can influence more effective and healthier exercise routines.
By focusing on a subscription model that includes the cost of the physical device, WHOOP differentiates itself from competitors that charge a higher one-time fee for their products. This model provides ongoing value and encourages users to stay engaged with their health data.
WHOOP's comprehensive monitoring of strain and recovery has given it a competitive edge, even as other brands like Fitbit have incorporated similar features. Beyond sports performance, WHOOP has conducted extensive research on predicting premature births, aiming to integrate these findings into their app. This commitment to broader health applications demonstrates WHOOP's dedication to advancing wearable health technology.
