This includes component design, state management, performance optimization, and the build tooling that keeps a fast\-moving product team shipping reliably. You will work closely with backend engineers, product designers, and QA to turn product requirements into polished, accessible, high\-performance interfaces \- and have real influence over how the frontend codebase scales. **Key Responsibilities** * Build and maintain complex, reusable React components and design system primitives used across the product surface * Own client\-side architecture decisions: state management (Redux, Zustand, or React Query), routing, data fetching, and caching strategies * Optimize bundle size, load times, and runtime performance using tools like Lighthouse, Webpack/Vite, and real\-user monitoring data * Implement responsive, accessible (WCAG 2\.1 AA) interfaces from Figma designs, collaborating directly with designers on feasibility and polish * Integrate with REST and GraphQL APIs, handling auth, error states, optimistic updates, and real\-time data via WebSockets * Write unit and integration tests with Jest and React Testing Library; maintain CI pipelines that catch regressions before production * Participate in code reviews, RFC discussions, and technical design documents that shape team\-wide frontend standards **What We Are Looking For** * 3\+ years of professional frontend engineering experience shipping production web applications * Deep expertise in JavaScript/TypeScript and modern React (hooks, context, suspense patterns) * Hands\-on experience with state management solutions and data\-fetching libraries (React Query, Redux Toolkit, or similar) * Strong CSS fundamentals and experience with modern styling approaches (Tailwind, CSS\-in\-JS, or CSS Modules) * Familiarity with build tooling (Vite, Webpack, Turborepo) and browser performance profiling * Bachelor's degree in Computer Science or equivalent practical experience * Bonus: experience with Next.js/SSR, design systems ownership, Cypress/Playwright E2E testing, or a background in design engineering
