Data Science Expert - AI Evaluation

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. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

2. 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

Qualified applicants may be asked to complete a brief technical assessment or submit additional information
