  • Strong understanding of performance optimization techniques, including lazy loading, code splitting, and application profiling.
  • Experience working from Figma designs and delivering pixel-perfect implementations.
  • Familiarity with Agile development practices, Git-based workflows, and modern frontend build tools such as Vite or Webpack.
  • Comfortable using AI-assisted development tools such as Claude, Claude Code, Cursor, or GitHub Copilot within daily engineering workflows.
  • Excellent written English communication skills and the ability to work independently in a remote, asynchronous environment.
  • Availability to consistently overlap with U.S. business hours.
  • Experience with Firebase, GraphQL, REST APIs, mapping libraries, micro-frontends, or B2B SaaS products is considered an advantage.
Benefits
  • Fully remote contractor opportunity based in Europe.
  • High level of ownership with end-to-end responsibility for frontend feature development.
  • Opportunity to work on a modern SaaS platform serving mission-critical business operations.
  • Collaborative environment with close interaction across engineering, product, and design teams.
