We're looking for a mid-to-senior React Developer to design and build modern, responsive web applications. The right person writes clean, maintainable component-based code, partners closely with designers and back-end engineers, and brings strong opinions on front-end architecture without losing sight of what the business actually needs. This role fits someone who's past the basics — comfortable owning features end-to-end, mentoring less experienced developers, and contributing to technical decisions about state management, performance, and tooling.

• Design, build, and maintain user-facing features in React
• Manage application state (Redux, Context API, Zustand, React Query, or similar)
• Integrate front-end with REST and/or Graph
  
  QL APIs
• Write clean, well-tested code (Jest, React Testing Library, Cypress, etc.)
• Participate in code reviews and contribute to engineering best practices
• Collaborate with designers, PMs, and back-end engineers in an agile environment
• Troubleshoot and debug production issues through to deployment

• 4+ years professional front-end development
• 3+ years building production applications with React
• Solid understanding of React hooks, component lifecycle, and modern patterns
• HTML5, CSS3, and modern styling (CSS-in-JS, Tailwind, Styled Components, or SCSS)
• Comfortable consuming REST APIs; async patterns and error handling
• State management experience (Redux, Context, Zustand, or React Query)
• Proficient with Git and modern dev workflows (PRs, code review, CI/CD)
• Strong testing mindset — unit, integration, and/or end-to-end
• Clear written and verbal communication

• Next.js or other React-based frameworks (Remix, Gatsby)
• Build tooling (Webpack, Vite, esbuild)
• Accessibility (WCAG) and responsive design
• Performance profiling (React Dev Tools, Lighthouse)
• Design systems or component libraries (MUI, Chakra, Radix, shadcn)
• Cloud platforms (AWS, Azure, or GCP)

• Self-directed and pragmatic — knows when to ship and when to refactor
• Comfortable across the front-end stack; willing to dig into unfamiliar code
• Collaborative; gives and receives feedback well
• Curious about new tools, but not chasing every shiny thing
