Job description

We’re looking for a Senior / Staff React Developer who’s passionate about building applications from scratch and making architectural decisions that shape the entire frontend. If you’re confident in working with pure React , enjoy working independently, and like writing maintainable, scalable code — we want to hear from you. 🙋‍♀️


💼 Your responsibilities:

  • Build and maintain React-based SPAs from the ground up — no templates, no boilerplate.
  • Take ownership of technical decisions and app architecture.
  • Use tools like React DevTools and Chrome DevTools to test and debug.
  • Write clean, modular, and testable JavaScript code.
  • Cooperate closely with other frontend/backend developers and product owners.


🧠 Our requirements:

  • 5+ years of experience in developing modern frontends in pure React.
  • Proven record of building projects or MVPs from scratch.
  • Confident in discussing architectural trade-offs and technology choices.
  • Deep understanding of JavaScript (ES6+), React hooks, and state management.
  • Experience with react-hook-form, TanStack Query or similar libraries is a plus.
  • Familiarity with Git and standard CI/CD workflows.


🌍 What we offer:

  • Fully remote work with flexible hours.
  • Private healthcare and Multisport card.
  • Involvement in international projects from day one.
  • Opportunity to take on technical leadership as the product grows.
