• Deliver reproducible code and well-organized analytical reports.


• Evaluate AI-generated outputs involving statistics, machine learning, experimentation, and quantitative reasoning.


• Create expert-level prompts, datasets, and reference solutions.


• Identify flawed methodologies, statistical errors, and weaknesses in quantitative reasoning.


• Provide structured feedback to improve AI model performance and capabilities.

Required Qualifications

• Proficiency in Python for data analysis, statistical computing, and machine learning.


• Experience with Pandas and familiarity with machine learning libraries such as scikit-learn.


• Demonstrated knowledge of applied statistics, experimental design, and machine learning.


• Experience developing, tuning, and evaluating machine learning models in practical settings.


• Strong data modeling skills and experience working with structured and unstructured data.


• Excellent written and verbal communication skills.


• Ability to produce reproducible code, precise technical documentation, and clear analytical reports.

Preferred Qualifications

• At least one year of experience at a leading company in technology, finance, or research.


• An advanced academic background or hands-on experience in data science, applied mathematics, statistics, or a related field.


• Experience collaborating on open or cross-functional data science projects.


• Strong analytical judgment and the ability to assess complex quantitative problems.

Compensation & Engagement

• Compensation: $245–$280 per hour.


• Engagement Type: Contractor.


• Work Arrangement: Fully remote.


• Project Focus: Applied science, advanced analytics, machine learning, statistical analysis, and experimentation.
