## About the Role

* 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 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.

## 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
