Why this grade This listing scored 48/100, which is a D. It lost the most ground on pay transparency. See the breakdown
- Description depth 20 / 20 How much the posting actually says about the work, measured in characters of real text.
- Pay transparency 12 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
- Freshness 8 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
- Remote clarity 8 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
- Corroboration 5 / 10 Whether more than one source carries this listing.
- Role specificity 0 / 10 Whether the listing is tagged well enough to tell what the role actually is.
-5 Ghost-job penalty — Deducted for signals that this posting may not be a real, currently-open role — staleness, repeated relisting, or talent-pool language.
Every figure above is arithmetic over the posting itself — its salary field, its text, its age, its tags and how many sources carry it. How the grades work →
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: Frontend Engineer
Type: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 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.
- 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.
