Key Responsibilities Front End Development Design, build, and maintain high‑quality, reusable, and scalable React components using React, TypeScript, and modern front‑end engineering practices. Implement user interfaces that are highly performant, accessible, responsive, and consistent with the organisation’s design system. Integrate front‑end applications with backend APIs, microservices, and event‑driven architecture. Deliver clean, secure, testable code following engineering best practices (SOLID principles, DRY, component isolation, secure‑by‑default). Utilise modern tooling and libraries including Webpack/Vite, Redux/Context/Zustand, React Query, and UI component frameworks. Support the evolution of front‑end architecture, including patterns for state management, routing, performance optimisation, and micro‑frontend approaches. UI/UX Collaboration Partner with UX/UI designers to translate wireframes, prototypes, and interaction designs into elegant, functional user interfaces. Advocate for user‑centred design, contributing to decisions around usability, accessibility, and interface consistency. Participate in design reviews and provide technical feedback on feasibility, accessibility, and implementation approach. Quality Engineering & Testing Establish and uphold modern front‑end testing practices including unit, integration, component, and end‑to‑end tests (e.g., Jest, React Testing Library, Cypress/Playwright). Support and improve CI/CD pipelines for front‑end applications to ensure reliable, automated deployments. Lead and contribute to front‑end code reviews, ensuring quality, maintainability, and adherence to standards and patterns.
