HTML/CSS – Senior Developers – AI Training
We're looking for Senior HTML/CSS Developers to join our Expert Network to help train and evaluate cutting‑edge AI models. If you have a background in Software Engineering or Frontend Development, you'll be invited to complete a quick 10‑ to 15‑minute test to assess your skills. Successful candidates will join Prolific as a participant, where you'll be paid to help AI understand and produce high‑quality frontend code and design implementation.
Researchers may pay up to $40/hr, depending on skills and experience. Tasks typically require one hour of uninterrupted work, though many are shorter.
What you’ll bring
- Educational Background: a BSc or higher in Computer Science, Software Engineering, Web Development, or a closely related technical field.
- Professional Experience: real‑world experience as a Senior Frontend Developer or UI Engineer specialising in HTML/CSS.
- Coding Proficiency: ability to independently build complex, responsive layouts and components without relying on frameworks or libraries.
- Code Quality: a high standard for clean, semantic markup and maintainable CSS, including adherence to BEM methodology, design tokens, and modern CSS standards.
- Attention to Detail: ability to spot subtle rendering issues, accessibility violations, specificity conflicts, or deprecated/non‑standard usage in model‑generated code.
What you'll be doing in the role
- Evaluate Code Accuracy: review AI‑generated HTML/CSS for functional correctness, semantic structure, and adherence to best practices.
- Validate Logic & Reasoning: audit the step‑by‑step explanations provided by AI for layout solutions and styling approaches to ensure they are technically sound.
- Annotate Model Performance: identify areas where a model produces inaccessible markup, inefficient selectors, deprecated attributes, or hallucinated CSS properties.
- Refine Technical Logic: provide structured feedback on how models reason through responsive design, component architecture, or design system implementation.
Key Technologies
- Core Languages: expert mastery of HTML5 and CSS3/4, including custom properties, animations, and modern layout systems.
- Frameworks & Methodologies: extensive experience with Tailwind CSS, SASS/SCSS, or CSS Modules, and familiarity with component‑driven design systems.
Benefits
- Competitive pay rates.
- Flexible hours.
- Ability to work from home.
