[Hiring] Web Development Expert @Mercor

Role Description

• 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 DevTools as muscle memory.
  • Command-line comfort: unzipping an archive, standing up a static local server, and untangling a broken image reference.
  • Enough JavaScript to read a page's scripts and understand their DOM impact.
  • Professional written English for task justification.
• Preferred:
  • Prior RLHF, preference-labeling, model-evaluation, or structured code-review work.
  • Pixel-perfect design-to-code experience.
  • Accessibility expertise (ARIA, semantic landmarks, heading hierarchy).
  • Familiarity with how LLMs fail at code generation.
  • Web scraping, archiving, or DOM-parsing background.
  • More than one completed Mercor project and availability in contiguous multi-hour blocks.
