About the role

AI Labs is seeking a contract Frontend Engineering Evaluator to assess how effectively AI systems produce production-quality user interfaces, including components, state handling, styling, accessibility, performance, responsiveness, and testing. The role requires 2–3 years of professional frontend experience, strong JavaScript/TypeScript, HTML, and CSS skills, experience with a modern frontend framework, excellent written English, and the ability to identify subtle implementation issues and provide evidence-based evaluations.

Key Responsibilities

  • Design task-specific grading criteria for frontend deliverables, including component implementations, UI bug fixes, refactors, and tests.
  • Evaluate AI-generated frontend code for correctness, state and edge-case handling, accessibility, performance, responsiveness, and maintainability.
  • Identify failures and subtle implementation issues that may not surface as runtime errors.
  • Review component design, state handling, styling, browser behavior, and frontend testing practices.
  • Assess whether interfaces follow responsive layout principles and web accessibility standards.
  • Write clear, evidence-based justifications for every evaluation score.
  • Apply consistent judgment across evaluations and iterate based on feedback from senior reviewers.
  • Follow complex instructions and distinguish clearly between established knowledge and inference.
  • Work independently on an hourly schedule while meeting the engagement's weekly availability expectations.

Required Qualifications

  • 2–3 years of professional frontend experience shipping production interfaces.
  • Strong command of JavaScript/TypeScript, HTML, and CSS.
  • Hands-on experience with a modern frontend framework such as React, Vue, Angular, or Svelte.
  • Solid grounding in component design, state management, browser rendering, responsive layout, and frontend testing.
  • Working knowledge of web accessibility standards, including WCAG, semantic HTML, and ARIA.
  • Experience reviewing other engineers' code.
  • Excellent written English.
  • Ability to follow complex instructions, reason through ambiguity, and spot subtle errors in code that renders correctly and runs without failing.
  • Ability to maintain a clear separation between what you know and what you are inferring.
  • Ability to work independently, learn new tools quickly, and take feedback well.
  • Based in and working from the US, Canada, or UK.
  • Available for 10+ hours per week for the full 12-week engagement.

Benefits and Perks

  • Remote contract engagement for candidates based in the US, Canada, or UK.
  • Hourly compensation of $50–$125 per hour.
