Senior Front End Developer

MCS Group is working with a growing technology business to recruit a Senior Front End Engineer to join its product engineering team. This is a hands-on role for an experienced React engineer who enjoys working on modern product experiences and solving front-end problems that go beyond traditional, fixed user interfaces.

The business is developing new AI-powered capabilities where elements of the user experience can be generated dynamically based on data, configuration and model outputs. You'll help build the front-end architecture that allows these experiences to work reliably, safely and at scale.

This is an opportunity to work on front-end engineering problems that are still relatively new across the industry. Rather than simply adding features to an established interface, you'll help shape how users interact with AI-powered software, including how dynamic content and components are generated, rendered and controlled within a production React application.

As their Senior Front-End Engineer you'll have plenty of ownership, work alongside an experienced engineering team and have a genuine opportunity to influence how the front-end architecture develops as the product grows.

The Role

The Front-End Engineer will work closely with Product, Design, Backend and AI teams to build and evolve modern web applications using React and TypeScript.

Your work will include:

• Building complex front-end applications using React and TypeScript
• Developing interfaces that can adapt or render dynamically based on data, configuration or AI-generated outputs
• Building conversational and chat-style product experiences
• Integrating AI-powered functionality into real customer-facing products
• Designing reusable components and scalable front-end architecture
• Managing complex application state, data flows and asynchronous interactions
• Optimising front-end performance and application responsiveness
• Building accessibility into products from the outset
• Working closely with Product and UX teams to turn new ideas into production-ready features
• Collaborating effectively with engineers working across different locations and time zones
• Contributing to technical decisions, code reviews and engineering standards

What We're Looking For

You'll ideally have:

• Strong commercial experience with React and TypeScript
• Deep knowledge of React including hooks, component architecture, state management and performance optimisation
• Experience building modern, complex web applications rather than predominantly static interfaces
• Exposure to dynamically generated or data-driven user interfaces
• Experience building AI-powered product features, not simply using AI coding tools
• Experience building chat, messaging or conversational interfaces
• A good understanding of web accessibility and how to incorporate it throughout development
• Experience working within distributed engineering teams
• Strong communication skills and the ability to work closely with Product, Design and Backend Engineering
• Experience working with generative AI, LLM-powered applications or interfaces where UI components are produced dynamically would be particularly valuable.
