• Proactively identify areas of improvement in the frontend architecture and help drive technical initiatives.

Requirements

• 5+ years of professional experience building web applications in modern JavaScript/TypeScript.
• Deep experience with React.js and modern features (hooks, context, portals, Suspense).
• Strong understanding of component design patterns and state management in React (e.g. Redux, Zustand, RTK).
• Experience with RESTful and GraphQL APIs.
• Familiarity with CI/CD workflows and frontend testing (Jest, React Testing Library, Cypress, etc.).
• Strong understanding of browser performance, web vitals, web accessibility (WCAG), and responsive design.
• Experience working in agile environments with cross-functional teams.
• Fluent English communication skills (written and verbal).

• Competitive salary based on performance and experience
• Chance of earning Klar stock options
• 26 days of paid vacation per year

• International work environment with amazing and highly skilled people
• A world class team that helps you evolve your skills in areas you're interested in
