Never send money to companies. Jobs on Himalayas will never require payment from applicants.

At Zeelo, we’re on a mission to revolutionize how frontline workers commute by delivering reliable, sustainable, and scalable transportation solutions. We partner with global leaders like Amazon, Barclays, and UPS, and we’re expanding after a successful Series B raise. If you’re passionate about building solutions, working in a scaling organization, and seeing the direct impact of your work—this is your seat on the bus.

About the role:

We’re looking for a Senior React Engineer to help lead the development of Zeelo’s next-generation web and mobile applications. You’ll work closely with design, product, and backend teams to deliver accessible, performant, and maintainable user experiences across both React and React Native (Expo) environments.

What You’ll Do

  • Build responsive, accessible applications using React and React Native / Expo with TypeScript.
  • Implement clean, modern UI architecture and reusable component systems.
  • Collaborate with designers and backend engineers to deliver features end-to-end.
  • Own testing strategy (unit, integration, E2E) and contribute to CI/CD quality pipelines.
  • Optimize applications for performance, accessibility, and localization.
  • Support app store releases, OTA updates, and ongoing monitoring with Sentry and Firebase.

What We’re Looking For

  • 5+ years of professional experience building production web and/or mobile applications.
  • Deep understanding of React, hooks, context, and modern design patterns.
  • Experience with Expo managed workflow, React Native, and EAS build tools.
  • Familiarity with TanStack Query, Zustand, MobX, or similar state management libraries.
  • Proven experience implementing testing frameworks (Jest, Vitest, React Testing Library, Playwright).
  • Strong grasp of performance optimization, accessibility (WCAG 2.1 AA), and responsive design.

Bonus Points

  • Experience with Framer Motion, Reanimated, or advanced animation libraries.
  • Exposure to PWA development, offline-first strategies, or hybrid architectures.
  • Experience integrating analytics, A/B testing, and modern observability tooling.
  • Excitement for exploring new tools and applying AI-assisted development to improve velocity and quality.
