Front-End Developer (React + Typescript)

We are supporting a client operating within a highly regulated environment and looking to engage an experienced contract engineer to join a critical delivery programme

This is an opportunity to join a fast-paced engineering team focused on delivering high-quality software solutions where hands-on development, AI-assisted engineering, and structured delivery practices are central to success.

Successful candidates will have experience working within heavily regulated or enterprise environments and be comfortable operating within formal governance frameworks, change controls, ticketing processes, and established development life cycles.

You’ll bring:

• Proven experience delivering software solutions in regulated environments
• Strong AI literacy and practical experience using AI-powered development tools
• Experience building and delivering AI-enabled solutions
• Hands-on experience with Claude Code in day-to-day engineering activities
• Excellent communication skills and the ability to work effectively within distributed teams
• A collaborative approach to code reviews, quality assurance, and secure development practices

We’re looking for a highly capable Front End Engineer who can combine exceptional React development skills with strong UI/UX capabilities to deliver intuitive user experiences.

Essential Skills

• Advanced React and TypeScript development
• UI/UX design, wireframing, prototyping, and user journey mapping
• Modern Front End tooling including Vite and npm
• Building complex forms, validation workflows, and multi-step user journeys
• Experience transforming designs into production-ready applications
• Enterprise design systems and component libraries
• WCAG 2.1 AA accessibility standards
• REST API integration
• SSO implementation experience
• Role-based user experiences and permissions models
• Frontend testing (Jest, Vitest, React Testing Library, etc.)
• Git/GitHub and modern engineering practices
• Hands-on experience with Claude Code and AI-assisted development workflows

Ideal Background

We’re particularly interested in candidates from a strong software engineering background who are actively involved in designing, building, and delivering production code. These opportunities are best suited to engineers who enjoy creating features, solving business problems through software, and operating within high-performing development teams, rather than purely infrastructure or platform-focused professionals.
