Job description
  • 1\. Role Overview Mercor is partnering with a leading AI research organization to engage experienced data scientists for a project focused on evaluating how well AI systems perform real-world data science work.

Key Responsibilities - Design precise, task-specific grading criteria for real-world data science deliverables (analyses, models, dashboards, experiment readouts, and written recommendations) - Score AI-generated and human work samples against those criteria, with detailed written justifications for every score - Apply consistent, evidence-based judgment so that scores are reproducible and defensible - Incorporate structured feedback from senior reviewers and iterate quickly on your work 3\. Ideal Qualifications - 5+ years of professional data science experience in industry - Background in business operations, product, or growth data science at top-tier technology companies - Deep fluency in experiment design and A / B testing, metric definition, SQL / Python analysis, and communicating findings to executive stakeholders - Exceptionally strong written communication - Detail-oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers - Prior experience with AI training, evaluation, or human-data projects is a strong plus 4\. Application Process - Submit your resume or relevant technical background to get started - Qualified applicants may be asked to complete a brief technical assessment or submit additional information
