• Score AI-generated and human work samples against established criteria, providing detailed written justifications for every score
• Apply consistent, evidence-based judgment to ensure scores are reproducible and defensible
• Incorporate structured feedback from senior reviewers and iterate quickly on your evaluations

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 skills
• 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
