What the work actually is

You will spend most of your time in an annotation or review interface looking at high-resolution clinical and dermoscopic images. Tasks rotate by project: assigning a diagnosis or differential to a lesion image, tagging structured attributes (primary and secondary morphology, color, border, configuration, distribution, Fitzpatrick phototype), scoring severity or progression across serial images, and reading model-generated assessments to judge whether the reasoning and terminology would survive scrutiny in a real clinic. A meaningful share of senior work is guideline authoring — writing the rubric that tells other annotators what a defensible image-based assessment looks like, and where an image simply does not support a confident call.

What the screen is looking for

Mercor's screening is AI-led and verification-heavy. Expect your license number, medical school, residency program, and post-residency years to be checked against public sources, so state them exactly as they appear on record. The domain portion probes whether you can describe a lesion in disciplined morphological language rather than jumping straight to a diagnosis, and whether you know the limits of image-only assessment — when history, palpation, dermoscopy, or biopsy is genuinely required. The judgment portion tests calibration: reviewers who mark every model output wrong, or who wave through fluent-sounding but clinically hollow text, both score poorly.

Logistics

  • Fully remote, asynchronous, contractor engagement — no patient contact, no on-call, no state-of-residence restriction beyond holding an active U.S. license.
  • Project-based volume, commonly 5–20 hours per week, with bursts when a labeling batch opens. Some projects request a minimum weekly commitment or attendance at a calibration session.
  • $270/hr is the observed band for this listing; rates vary by project, task type, and whether you take on guideline-writing or QA responsibilities, and are not guaranteed.
  • A color-accurate display and reliable broadband matter more here than on most annotation work — subtle erythema and pigment distinctions are the job.
