Frontend Engineer Position: Frontend Engineer Type: Freelance Hourly Contract Compensation: $90/hour Location: Remote About the Opportunity This opportunity is for experienced Frontend Engineers and Full-Stack Developers interested in evaluating AI-generated web interfaces and code. The work focuses on comparing AI-generated frontend implementations against real-world reference websites, assessing both visual fidelity and underlying code quality. This is an evaluation-focused role rather than a traditional development position. The key requirement is the ability to identify how a webpage is constructed, recognize technical shortcuts, and provide precise, evidence-based evaluations. What You'll Do • Render a reference webpage and two AI-generated implementations at a 1920×1080 viewport and evaluate which version most accurately reproduces the reference. • Compare visual fidelity across different interface states, including layout, spacing, typography, colors, borders, images, layering, and overflow behavior. • Review the source code of AI-generated implementations and assess HTML structure, CSS architecture, responsiveness, maintainability, and implementation quality. • Identify technical shortcuts such as excessive hardcoded positioning, unnecessary absolute positioning, poorly structured markup, or image-based recreations. • Test responsive behavior across different viewport sizes and identify layout or usability defects. • Use browser DevTools to inspect elements, computed styles, DOM structure, and interactive states. • Provide specific, evidence-based written justifications explaining why one implementation is stronger than another. • Identify genuinely broken evaluation tasks while distinguishing them from tasks that are simply challenging. Required Qualifications • 3–8 years of professional web development experience, primarily in frontend or full-stack engineering. • Strong hands-on experience with HTML, CSS, JavaScript, responsive web development, and modern frontend engineering practices. • Deep understanding of semantic HTML, Flexbox, CSS Grid, media queries, and responsive layouts. • Ability to read and understand both modern and legacy web layouts, including float-based and table-based designs. • Strong proficiency with browser Developer Tools, including DOM inspection, computed styles, viewport testing, and interactive state debugging. • Comfortable working from the command line, including extracting archives, running local development servers, and troubleshooting asset paths. • Sufficient JavaScript knowledge to understand how scripts interact with the DOM and user interactions. • Strong professional written English and the ability to provide clear, detailed technical justifications. • Strong attention to detail and the ability to identify subtle visual and structural differences. Preferred Qualifications • Prior experience with RLHF, preference labeling, AI model evaluation, structured code review, or human-feedback projects. • Pixel-perfect design-to-code experience, including work with design systems, templates, or production web interfaces. • Knowledge of web accessibility, including ARIA, semantic landmarks, and heading hierarchy. • Familiarity with common failure patterns in AI-generated frontend code. • Experience with web scraping, website archiving, DOM parsing, or working with complex crawled website structures. • Previous experience completing AI evaluation projects and working in multi-hour evaluation sessions. Equipment Requirements • Desktop or laptop capable of displaying a 1920×1080 viewport. • Ability to run a local development environment and static web server. • Administrator access to your own computer for installing required development tools. Important Project Requirements • Each evaluation unit typically takes 2–3 hours and is completed within a defined time window. • This is not microtask work and requires the ability to dedicate uninterrupted blocks of time to individual evaluations. • A functioning local development environment is required. • The role is intended for practicing web developers with strong frontend and UI implementation expertise. • Backend-only, ML/data-science-only, mobile-native-only, and DevOps-only backgrounds are generally not suitable for this evaluation work. Compensation • Competitive compensation of $90/hour. • Independent contractor engagement. • Compensation is based on completed evaluation work in accordance with project requirements.
