Frontend Developer - React / TypeScript

Ncounter is supporting a technology consultancy looking for an experienced Frontend Developer to work on modern digital services across Central Government. You will join an established engineering team delivering secure, accessible applications used within complex public sector environments. This is a hands-on development role with genuine ownership across the frontend, working closely with backend engineers, architects and product teams to turn requirements into reliable, intuitive digital services.

The role:
• Build and maintain modern applications using React and TypeScript, taking features from component through to service integration
• Develop accessible, responsive interfaces, dashboards and interactive user journeys
• Integrate frontend applications with REST APIs, authentication services and role-based access controls
• Build polished prototypes to demonstrate new concepts and help shape requirements with stakeholders
• Contribute to testing, code reviews, CI/CD and frontend engineering standards
Your background:
• 5+ years of commercial frontend development experience with strong React and TypeScript expertise
• Strong JavaScript, HTML and CSS fundamentals, ideally including Tailwind CSS or similar
• Experience integrating REST APIs and building secure, production-grade applications
• Jest and React Testing Library experience, alongside strong Git-based development practices
• Experience building prototypes using Lovable or comparable tools
• A good understanding of accessibility, responsive design and developing intuitive interfaces for varied user groups

Experience with Entra ID, MSAL, Keycloak, React Router, Redux, Vite, Radix UI/shadcn, data visualisation, Docker or GitHub Actions would be beneficial. Exposure to AI-enabled products is also useful, but this is fundamentally a frontend software engineering position rather than an AI specialist role.

Candidates must be eligible for UK Security Clearance. This is a strong opportunity for a React Developer who wants to work on complex, high-profile digital transformation programmes where usability, accessibility and engineering quality genuinely matter.
