About The Role The role focuses on building polished, high-performance user interfaces for products used by millions of customers. Work spans complex client-side state management, design system architecture, and rendering performance optimization in modern React and TypeScript codebases. You will partner closely with product designers, backend engineers, and PMs to ship user-facing features end-to-end, with direct ownership over what users see and interact with.

Key Responsibilities

Build and maintain production user-facing features using React, TypeScript, and modern CSS frameworks Architect and evolve a shared component library, driving consistency across web and responsive mobile web surfaces Own performance: bundle size budgets, Core Web Vitals, code-splitting, and lazy-loading strategies Integrate REST and GraphQL APIs, handling caching, error states, and optimistic UI updates Write comprehensive tests with Jest and React Testing Library; contribute to E2E coverage with Playwright or Cypress Participate in design reviews, code reviews, and pairing sessions with designers and engineers Instrument and monitor client-side errors and performance using tools like Sentry and Datadog What We Are Looking For 3–6 years of frontend engineering experience building and shipping production web applications Deep expertise in JavaScript/TypeScript and React (or a comparable modern framework) Strong grasp of browser internals: rendering pipeline, accessibility, cross-browser compatibility Experience with state management at scale (Redux, Zustand, or similar) and modern build tooling (Vite, Webpack) Track record of measurable frontend performance improvements in production environments Bachelor's degree in Computer Science or equivalent practical experience Bonus: experience with design systems (Storybook, Figma workflows), mobile frameworks (React Native), or GraphQL tooling
