Job Description
1. Role Overview
n
Mercor is partnering with a leading AI research organization to engage experienced UI/UX and product designers for a project focused on evaluating how well AI systems perform real-world digital product design work.

engineering/production
handoff)
n
Score AI-generated and human work samples against those criteria, with detailed written justifications for every score
