Job Description
About The Role The role focuses on building user-facing products where rendering performance, interaction quality, and design fidelity are treated as core engineering requirements, not afterthoughts. Expect to work on a large React-based frontend spanning complex dashboards, real-time data views, and customer-critical flows used by thousands of users daily.
You will sit at the intersection of product design and platform engineering — translating Figma specs into performant, accessible components and shaping frontend architecture decisions alongside backend engineers and designers.
Key Responsibilities
- Build and maintain production features in React and TypeScript, shipping weekly to a customer-facing web application
- Design reusable component architecture with a modern styling system (Tailwind, CSS-in-JS, or design tokens), driving consistency across product surfaces
- Own frontend performance: bundle optimization, lazy loading, Core Web Vitals monitoring, and rendering performance for data-heavy views
- Integrate with REST and GraphQL APIs, handling caching, optimistic updates, and real-time data via WebSockets
- Write comprehensive unit and integration tests using Jest, React Testing Library, and Playwright; maintain high coverage on critical user flows
- Collaborate with designers to implement pixel-accurate, accessible (WCAG 2.1 AA) interfaces and push back constructively on UX tradeoffs
- Participate in architecture reviews, mentor mid-level engineers, and contribute to frontend tooling and CI/CD pipelines
What We Are Looking For
- 3–6 years of professional frontend engineering experience, including at least 2 years shipping production React applications at scale
- Deep proficiency in TypeScript, modern JavaScript (ES6+), and state management patterns (Redux, Zustand, or React Query)
- Demonstrated experience with performance profiling and optimization using browser DevTools, Lighthouse, or equivalent tooling
- Strong grasp of accessibility standards and responsive design across browsers and devices
- Experience with build tooling and bundlers (Vite, Webpack, Turborepo) and modern frontend CI/CD workflows
- Bachelor’s degree in Computer Science or equivalent practical experience
- Bonus: Experience with Next.js or server-side rendering, design system ownership, Storybook, or frontend observability tools like Datadog RUM or Sentry
