Key Responsibilities

• Evaluate AI-generated responses involving data science, machine learning, statistics, and quantitative reasoning.
• Create expert-level prompts, datasets, evaluation tasks, and reference solutions.
• Review statistical analyses, machine learning workflows, and experimental methodologies for accuracy and rigor.
• Identify flawed assumptions, methodological errors, statistical mistakes, and weaknesses in quantitative reasoning.
• Assess the quality, correctness, and completeness of analytical solutions.
• Provide structured feedback and detailed explanations to support model improvement.
• Develop realistic scenarios involving data analysis, predictive modeling, experimentation, and statistical inference.
• Document findings and recommendations clearly and accurately.

Required Qualifications

• Strong expertise in data science, statistics, machine learning, analytics, or a related quantitative field.
• Proficiency in Python and common data science libraries such as Pandas, NumPy, Scikit-learn, or similar tools.
• Strong understanding of statistical analysis, hypothesis testing, experimentation, and data modeling.
• Experience working with large datasets and quantitative problem-solving.
• Ability to identify methodological weaknesses and analytical errors.
• Excellent written communication skills for explaining technical concepts clearly.
• Strong analytical thinking and attention to detail.
• Ability to work independently in a remote environment.

Preferred Qualifications

• At least one year of experience working at a leading technology, finance, research, or data-driven organization.
• Experience in machine learning model development, experimentation, or quantitative research.
• Background in predictive analytics, statistical modeling, causal inference, or applied machine learning.
• Experience designing experiments and evaluating model performance.
• Familiarity with AI systems, model evaluation, or data-centric AI workflows.
• Based in an English-speaking country.
• Strong ability to communicate complex quantitative concepts to technical and non-technical audiences.

Compensation

• $245-$280/hour
• Project-based work
• Fully remote opportunity.
• Flexible workload with no fixed schedule.
• Applications reviewed on a rolling basis.
• No prior AI experience required.
• Work focuses on evaluating and improving AI capabilities in statistics, machine learning, experimentation, and quantitative reasoning.
