Frontend Architect

ABOUT THE ROLE Our client is looking for a Frontend Architect to own the frontend architecture of that platform end to end. This is a senior individual contributor role. You will set the technical direction for the frontend, define the patterns other engineers build against, and stay hands-on enough to prove your own designs. There are no direct reports – the authority here is technical rather than managerial. KEY RESPONSIBILITIES • Own and evolve the frontend architecture for the platform and the applications built on it • Build out and maintain the micro-frontend architecture, defining integration patterns across the application shell, shared libraries, design system, authentication services and backend APIs • Design and implement modular applications using React, TypeScript, JavaScript, HTML5 and CSS • Architect operational dashboards, control-room views and 3D or interactive visualizations of equipment, sites and assets • Build reusable component libraries, layout frameworks and common engineering patterns • Ensure performance, scalability, maintainability, security, usability and accessibility across the frontend estate • Provide hands-on technical leadership through design reviews, code reviews and mentoring • Work closely with product owners, UX designers, backend architects and QA to translate requirements into robust frontend solutions WHAT WE ARE LOOKING FOR • 12 or more years of frontend engineering experience, with a substantial period at architect level • Deep, current expertise in React and TypeScript • Demonstrable experience designing and owning micro-frontend architecture – Module Federation, single-spa, web components or similar. We are looking for people who have defined the architecture, not only worked within one • Three.js is a mandatory requirement. You will be working on 3D and interactive visualization of industrial assets, and we need someone who has built with it • Strong command of frontend routing, state management, API integration, authentication flows and role-based access • Experience integrating with REST, GraphQL, WebSockets or real-time data services • Performance engineering: bundle optimization, lazy loading, rendering performance and Core Web Vitals • Testing frameworks such as Jest, React Testing Library, Cypress or Playwright • Evidence of architectural ownership – setting direction that other engineers follow, and carrying people with you through design decisions DESIRABLE • WebGL, Babylon.js, Unity3D or similar 3D and interactive technologies beyond Three.js • Experience with data-dense operational or monitoring interfaces • Industrial, manufacturing or energy sector exposure – though this is not essential, and we welcome candidates from any sector with the right frontend depth Show more Show less
