About the Role Mercor is partnering with a leading AI research lab to hire experienced Data Scientists specializing in AI task evaluation and statistical analysis.

Dimensional Analysis: Examine performance variations across finance sub‑domains, file structures, and evaluation criteria. Visualization & Reporting: Build dashboards and analytical reports that highlight edge cases, performance clusters, and opportunities for improvement. Framework Enhancement: Recommend refinements to rubric design, evaluation metrics, and task structures based on empirical findings.

Required Qualifications Strong foundation in statistical analysis, hypothesis testing, and pattern recognition. Proficiency in Python (pandas, scipy, matplotlib/seaborn) or R for data analysis. Hands‑on experience with exploratory data analysis (EDA) and feature interpretation. Understanding of AI/ML evaluation methodologies and LLM performance metrics. Skilled in using Excel, SQL, and data visualization tools (e.g., Tableau, Looker). Preferred Qualifications Experience with AI/ML model evaluation or quality assurance pipelines. Background in finance or interest in learning financial domain structures. Familiarity with benchmark datasets, failure mode analysis, and evaluation frameworks. 2–4 years of relevant professional experience in data science, analytics, or applied statistics. More About the Opportunity Commitment: Part‑time, 20–25 hours/week Schedule: Fully remote and asynchronous — work on your own time Duration: 1–2 months, with strong potential for extension Start Date: Immediate Compensation & Contract Terms Hourly Rate: $100–$120/hour (based on experience and region) Payments: Weekly via Stripe Connect for approved work ⚡ PS: Mercor reviews applications daily.
