Responsibilities
🚀 Hiring! Frontend Engineer — Web Replication Preference Rater $90/hr 💰 Location: RemoteMercor is building a high-quality dataset of human preference judgments on AI-generated frontend code. You'll be shown a reference web page alongside two candidate replications produced by AI models, and you'll decide which replication is better — then explain why in writing that a model can learn from.This is evaluation work, not authoring. You won't be building sites from scratch. You'll be reading someone else's HTML and CSS, running it locally, comparing it pixel-by-pixel against a target, and articulating exactly where and why it falls short.🟢 Qualifications3+ years of professional web development experience, primarily in frontend or full-stack work.Fluency in hand-written HTML and CSS: semantic markup, flexbox, grid, media queries, and older float- and table-based layouts you can still read and reason about.Working command of browser devtools — element inspection, computed styles, the box model, and the network panel.Enough JavaScript to read a page's scripts and understand what they do to the DOM, even if you don't write JS daily.Comfort in a terminal: cloning a folder and serving it over a local static server without help.
