React Developer

As a Frontend Engineer specializing in React.js at Capco, you will be at the heart of designing and developing modern, high-performance, and accessible user interfaces for high-value digital solutions in the banking and insurance sectors. You will work closely with product, design, and backend teams to deliver robust, high-quality, and scalable applications.
Your responsibilities will include:
• Designing and developing responsive and performant user interfaces using React.js, while ensuring accessibility and user experience best practices.
• Collaborating on the definition of frontend architecture, alongside Tech Leads and other technical experts.
• Integrating backend APIs and handling complex state management and user interactions effectively.
• Participating in the implementation of automated testing (unit, integration, end-to-end) and continuous integration pipelines.
• Contributing ideas on technology choices, frameworks, and libraries, and playing an active role in code quality improvement.
• Working in an agile environment, and collaborating effectively with UX/UI designers, Product Owners, and backend developers.
• Getting involved in the Capco frontend chapter through workshops, code reviews, tech watch, tech talks, and more.
At Capco, our stack includes Next.js 15 and therefore React.js 19. Our backend developers use Java / Spring Boot, and in some client contexts, we also offer NestJS—perfect for fullstack developers!
We also welcome React Native developers when responsive web solutions no longer meet our clients' needs.
