About the job Mercor connects elite creative and technical talent with leading AI research labs. Headquartered in San Francisco, our investors include Benchmark , General Catalyst , Peter Thiel , Adam D'Angelo , Larry Summers , and Jack Dorsey . Position Position: Frontend EngineerType: Contract Compensation: $90/hour Location: Remote Role Responsibilities Render a reference page and two candidate replications at 1920×1080. Judge which is the closer reproduction, state by state.
Diff visual fidelity in detail: box model and spacing, typography (family, size, weight, line-height, letter-spacing), color and border treatment, image and asset handling, z-order, and overflow. Read the source of both attempts and grade construction quality. Distinguish a replication that is genuinely correct from one that merely looks correct at one viewport. Test responsiveness. Identify defects such as a nav bar that looks right at 1920px but collapses at 1400px. Write specific, evidence-cited justifications for every preference.
Provide detailed explanations like "B nests the article body in a single absolutely-positioned div, so the text overlaps the footer below 1600px, while A uses normal document flow." Use the "this task is broken" escape hatch with judgment. Distinguish a task that genuinely cannot be completed from one that is merely hard.
Qualifications
Must-Have 3–8 years of professional web development experience in frontend or full-stack work. Fluency across web eras, including legacy layouts like used for layout. Command of hand-written HTML and CSS : semantic markup, flexbox, grid, media queries, and legacy float- and table-based layouts. Browser Dev Tools as muscle memory. Command-line comfort: unzipping an archive, standing up a static local server, and untangling a broken image reference. Enough Java Script to read a page's scripts and understand their DOM impact. Professional written English for task justification.
