Snr Code Reviewer - HTML/CSS

We’re looking for senior front-end specialists who have at least seven years of professional experience with modern HTML5, CSS3 (Flexbox, Grid, custom properties), responsive design, accessibility (WCAG 2.2), and cross-browser debugging. You should demonstrate a sharp eye for semantic markup, performance-minded styling, and clear written English for concise feedback.

Your task is to audit annotator reviews of AI-generated HTML/CSS snippets. For each submission you’ll spin up a quick sandbox, verify that the code meets the prompt, renders correctly across breakpoints, follows accessibility and security best practices, and avoids anti-patterns such as excessive specificity or layout shifts. You’ll correct any mis-ratings, provide targeted feedback, and ensure every annotation aligns with our quality rubric—safeguarding the data that trains next-generation AI design tools.
