The work is flexible and remote, with a short assessment required before participating.
Responsibilities - Evaluate generated HTML and CSS for correctness, semantic quality, and adherence to good practice. - Check the soundness of model explanations for layout and styling decisions. - Execute and render code to review appearance and cross-browser behaviour. - Annotate accessibility defects, poor selector choices, outdated attributes, and unsupported CSS. - Give structured feedback on responsive design, component patterns, and design system work.

Nice to have - Experience with Tailwind CSS, Sass/SCSS, CSS Modules, and component-driven design approaches. - Familiarity with browser developer tools, accessibility checkers, and cross-browser testing tools.
Benefits and work setup - Flexible remote tasks with rates advertised up to $40 per hour, depending on qualifications and experience. - A 10 to 15 minute assessment precedes participation. Be prepared for some assignments requiring an uninterrupted hour; many take less time.
