  • Communicate trade-offs around performance, accessibility, UX, and delivery timelines clearly to both technical and non-technical stakeholders
  • Ensure operational excellence by maintaining frontend observability, performance budgets, error monitoring, and documentation

Requirements:

  • 6+ years of frontend engineering experience, with deep expertise in TypeScript and React
  • Strong fundamentals in modern frontend architecture: component design, state management, data fetching, and API integration
  • Experience building and maintaining production-grade web applications in high-traffic environments
  • Proven ability to optimize performance, accessibility (a11y), and responsiveness
  • AI-native workflow: hands-on experience integrating AI coding tools into daily frontend development
  • Excellent communication skills and the ability to work cross-functionally in fast-moving teams

Nice to have:

  • Experience building B2B, E-commerce, or marketplace user interfaces
  • Familiarity with design systems, Storybook, and scalable UI libraries
  • Experience with Next.js, server-side rendering, or micro-frontend architectures
