We are seeking experienced Frontend Engineers to evaluate AI-generated web interfaces and code. Rather than building new products, you will compare AI-generated frontend implementations against real-world reference websites and determine which implementation is more accurate, robust, and well-constructed.
This role is ideal for frontend or full-stack engineers with strong HTML, CSS, JavaScript, responsive design, browser DevTools, and web development fundamentals , including the ability to evaluate both how a page looks and how it is built.
Important: This project is evaluation-focused, not frontend authoring.
Run a reference website and two AI-generated implementations locally.
Evaluate each implementation at a 1920×1080 viewport and across required interactive states.
Compare visual fidelity, including:
Layout, spacing, and box model
Typography and text styling
Colors, borders, and visual treatments
Images and asset handling
Z-index, overflow, and positioning
Inspect the underlying HTML, CSS, and JavaScript to assess implementation quality.
Identify whether an implementation genuinely recreates the interface or relies on shortcuts such as excessive hardcoding, inappropriate absolute positioning, or screenshot-based rendering.
Test responsive behavior and identify layout defects at different viewport sizes.
Provide specific, evidence-based explanations supporting every preference.
Determine whether a task is genuinely broken or simply difficult and should still be evaluated.
3–8 years of professional web development experience , primarily in frontend or full-stack development.
Strong command of HTML and CSS , including:
Semantic HTML
Flexbox
CSS Grid
Media queries
Responsive design
Legacy float- and table-based layouts
Strong understanding of browser rendering and frontend architecture.
Comfortable using Browser DevTools , including inspecting elements, computed styles, viewport dimensions, and interactive behavior.
Comfortable working from the command line, including extracting archives and running local development servers.
Working knowledge of JavaScript sufficient to read and understand DOM-manipulating scripts.
Ability to evaluate both modern and legacy web interfaces.
Strong written English and the ability to provide precise, evidence-based technical reasoning.
Availability for 2–3 hour contiguous work sessions , as each evaluation unit is timed.
You will need:
A desktop or laptop capable of displaying a 1920×1080 viewport .
A real local development environment.
Administrator access to your computer to install and run a local server.
Ability to download, extract, inspect, and run website source files locally.
Tablets, Chromebooks, or locked-down devices that cannot run a local static server are not suitable for this project.
Previous AI evaluation, RLHF, preference labeling, or structured code-review experience.
Pixel-perfect design-to-code experience.
Accessibility expertise, including ARIA, semantic landmarks, and heading hierarchy .
Familiarity with common LLM-generated coding errors.
Experience with web scraping, website archiving, or DOM parsing.
Experience working with messy or legacy website codebases.
Multiple completed engagements on similar evaluation projects.
This opportunity is intended for practicing web developers with strong frontend skills.
Backend-only, ML/data science-only, mobile-native, and DevOps-only backgrounds are not suitable for the role. Designers without coding experience and developers who have only worked within component libraries without hands-on CSS experience may also struggle with the evaluation requirements.
Prior project experience: You must have completed at least one previous engagement with the platform in full . This project is not onboarding new experts without prior completed engagement experience.
Independent contractor engagement.
Fully remote.
Flexible scheduling, subject to the requirement for contiguous multi-hour work sessions.
Each evaluation unit typically takes 2–3 hours and is timed.
Projects may be extended, shortened, or concluded early depending on project requirements and performance.
Payments are made weekly based on services rendered.
H-1B and STEM OPT candidates are not currently supported.
Work will not require access to confidential or proprietary information belonging to another employer, client, or institution.
Apply your frontend expertise to the evaluation of AI-generated code .
Work on challenging real-world web interfaces across different eras and development styles.
Help improve the visual fidelity, responsiveness, architecture, and reliability of AI-generated frontend code.
Contribute to the development and evaluation of next-generation AI systems.
Ideal Candidate: A hands-on frontend engineer with strong HTML/CSS fundamentals, excellent visual judgment, browser and debugging expertise, and the ability to explain precisely why one implementation is technically and visually superior to another.
