You will own the client side of our applications - from component architecture and state to performance and testing - and work closely with our backend (Python) and design teams. We are open on framework: we want real production depth in Angular or React. What matters is that you can reason from first principles about components, state, rendering and performance, rather than following one framework's recipes. Our products use both, so you should be willing to work in the one you know less well. This is a builder's role. You should be comfortable writing clean, typed TypeScript, reasoning about how and when your UI re-renders, and shipping complex interfaces that hold up in production. What You'll Do\nDesign, build, and maintain front-end applications in Angular or React - components, state, routing, and data flow.\nWrite clean, reactive code using modern patterns - RxJS and Angular Signals, or React hooks and a data- fetching layer such as React Query.\nOwn front-end performance: rendering and change detection, bundle size, and load time.\nBuild complex, data-heavy UIs and forms with robust validation.\nIntegrate and consume REST APIs, handling loading, error, and edge states cleanly.\nWrite meaningful front-end unit tests for the components you ship.\nUphold UI/UX consistency and mentor less experienced developers. What We're Looking For This is a senior front-end role - we expect real depth in at least one major framework, not surface familiarity with several.\n5+ years of relevant, hands-on front-end development experience.\nAngular or React - genuine production experience with components, state management, forms, routing, and data flow. Depth in one is required; experience in both is a plus.\nStrong TypeScript, and solid HTML/CSS with responsive, cross-browser layouts.\nAbility to reason about and fix rendering performance - change detection in Angular, or re-render and memoisation behaviour in React.\nReactive and asynchronous data flow - RxJS streams, or hooks, effects and async state in React.\nFront-end testing (Jasmine/Karma, Jest, Vitest, or React Testing Library).\nComfort consuming REST APIs and working with Git.\nWillingness to work in the other framework - if you are an Angular developer we expect you to pick up React, and the other way round. This Role Is Not a Fit If…\nYou have not built and shipped a real production application in either Angular or React.\nYou write only basic HTML/CSS with no real framework or TypeScript depth.\nYou will only work in one framework and are not open to the other.\nYou cannot reason about rendering performance or why your UI updates when it does.\nYou have no experience writing front-end tests. Nice to Have\nProduction experience in both Angular and React.\nAngular Signals, or modern React patterns (Server Components, Suspense).\nState management at scale - NgRx, Redux, Zustand, or similar.\nNext.js, or Angular SSR / hydration.\nA strong eye for design and accessibility (a11y).\n• Some familiarity with the backend (Python / REST / AWS).
