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.
RESPONSIBILITIES:
- 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
QUALIFICATIONS:
- 2–4 years of professional software engineering experience
- Proficiency in web development using JavaScript/TypeScript, React, and Node.js
- Experience building and integrating RESTful APIs
- Familiarity with frontend architecture and building reusable UI components or design systems
- Experience with design implementation, taking mockups in tools like Figma and making them reality
- Understanding of internationalization (i18n) and localization best practices
- Familiarity with CSS, responsive design, and modern layout techniques
- Experience with relational databases such as PostgreSQL or MySQL
- Experience working with build systems and CI/CD tools (CircleCI, GitHub Actions)
- Strong communication skills and ability to collaborate with technical and non-technical stakeholders
- Experience implementing RTL support using CSS logical properties and direction-based styling
- Familiarity with bidirectional (BiDi) text handling and localization edge cases
- Experience with design system tooling (e.g., Storybook) or cross-platform component libraries
- Exposure to translation platforms or localization pipelines
- Exposure to design tokens, managing tokens for color modes and multiple themes
- Backend experience in languages like Java, Python, or C#
- Familiarity with cloud delivery platforms (Cloudflare, Vercel, CloudFront)
- Experience with accessibility standards (WCAG) and inclusive design
