Job description

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 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

Requirements

  • 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.
