Description

  • Review AI-generated HTML/CSS for functional correctness, semantic structure, and adherence to best practices.
  • Audit AI explanations for layout and styling solutions to ensure the reasoning is technically sound.
  • Render model-generated markup and stylesheets to verify visual output and cross-browser behavior.
  • Identify inaccessible markup, inefficient selectors, deprecated attributes, and hallucinated CSS properties in model outputs.
  • Provide structured feedback on responsive design, component architecture, and design system implementation.

  • Ability to independently build complex, responsive layouts and components without relying on frameworks or libraries.
  • Expert understanding of the CSS cascade, specificity, box model, Flexbox, CSS Grid, accessibility standards (WCAG), and cross-browser compatibility.
  • High standard for clean, semantic markup and maintainable CSS, including BEM methodology, design tokens, and modern CSS standards.
  • Expert mastery of HTML5 and CSS3/4, including custom properties, animations, and modern layout systems.
  • Extensive experience with Tailwind CSS, SASS/SCSS, or CSS Modules, and familiarity with component-driven design systems.
  • Proficiency with browser DevTools, accessibility auditing tools such as axe and Lighthouse, and cross-browser testing platforms.
  • Background in Software Engineering or Frontend Development.
  • Ability to complete a 10- to 15-minute test to assess skills, if invited.
  • Preparedness to complete paid tasks that require one hour of uninterrupted work.

Benefits

  • Up to $40/hr depending on skills and experience.
  • Competitive pay rates.
  • Flexible hours.
  • Ability to work from home.
  • Quick onboarding after passing the assessment, with the ability to join in about 15 minutes.
