We’re seeking a talented React Frontend Developer to join the engineering team at a leading wellness-tech company.


The company is a profitable, founder-led U.S. wellness tech business that’s just been repurchased from private equity and is undergoing a major transformation. With a stable core and fresh product focus, the next chapter is about evolving from transactional bookings to a broader, personalized wellness platform—leveraging device health data and habit-building experiences to deepen engagement. It’s a rare blend of startup-style velocity with mature scale and runway, where impactful work ships fast and shapes the company’s next generation.


You’ll play a key role in building and maintaining their web platform — ensuring that users experience the same quality, smoothness, and reliability they expect from our mobile apps. You’ll collaborate closely with designers, backend engineers, and mobile teams to create beautiful, intuitive, and high-performing interfaces using React, TypeScript, and modern frontend tools. The ideal candidate has a strong eye for design, a solid understanding of REST API integrations, and experience in performance optimization for real-world production apps.



Responsibilities

  • Develop, test, and maintain React-based web applications with clean, maintainable, and scalable code.
  • Collaborate with UI/UX designers, backend engineers, and product managers to bring features and workflows to life.
  • Integrate RESTful APIs and manage application state efficiently using tools like Redux, Zustand, or React Query.
  • Ensure cross-browser and cross-device compatibility while maintaining accessibility and responsiveness.
  • Optimize frontend performance, focusing on speed, smooth animations, and user experience consistency.
  • Participate in code reviews, architecture discussions, and feature planning sessions.
  • Implement and maintain component libraries and design systems to ensure consistency across the platform.
  • Collaborate with the mobile teams to align web and app experiences within our ecosystem.
  • Stay updated with emerging frontend technologies, React updates, and web performance techniques.



Qualifications

  • Proven experience developing and deploying React applications (portfolio or live links preferred).
  • Strong proficiency in JavaScript (ES6+) and TypeScript.
  • Deep understanding of React, Hooks, Context API, and modern state management.
  • Experience integrating RESTful APIs and working with JSON-based data structures.
  • Familiarity with Next.js or Vite for optimized builds and server-side rendering (SSR).
  • Experience with Git, CI/CD pipelines, and automated testing frameworks (e.g., Jest, Testing Library).
  • Strong debugging, profiling, and performance optimization skills.
  • Excellent communication and collaboration skills in a remote team environment.


Nice to Have

  • Knowledge of Webpack, Babel, or build optimization tools.
  • Familiarity with Google Tag Manager, analytics integrations, or SEO optimization for React apps.
  • UI/UX design sensibility and attention to visual polish.
  • Passion for health, wellness, and building applications that positively impact users’ lives.
