Compensation Annualized Compensation: $288,000–$384,000 per year

Hourly Rate: $150–$200 per hour

Employment Type: Contractor

Work Arrangement: Remote

The annualized figure is based on 40 hours per week and 48 working weeks per year. Actual earnings will depend on project workload, assignments, and hours worked. About The Role We are seeking data scientists and quantitative professionals with experience at leading organizations to evaluate and improve how AI models handle statistics, machine learning, experimentation, and quantitative reasoning.

In this role, you will assess AI-generated responses to data science and quantitative problems, develop expert-level prompts and reference solutions, and identify methodological weaknesses, statistical errors, and flawed reasoning.

Your expertise will help strengthen AI model performance by ensuring that outputs demonstrate sound analytical methods, statistical rigor, and reliable quantitative reasoning.

Key Responsibilities

• Evaluate AI model outputs across data science, statistics, machine learning, and quantitative problem-solving tasks.
• Create expert-level prompts that test analytical ability, statistical understanding, and machine learning knowledge.
• Develop datasets and reference solutions for evaluating model performance.
• Identify flawed methodologies, statistical errors, and weaknesses in quantitative reasoning.
• Assess the accuracy, validity, and rigor of AI-generated analytical solutions.
• Provide structured feedback highlighting errors, limitations, and opportunities for improvement.
• Communicate technical findings and statistical concepts clearly to support model development.
• Contribute to improving AI model capabilities in data science and quantitative analysis.

Required Qualifications

• At least one year of professional experience at a leading company in technology, finance, or research, with at least part of this experience gained within the past three years.
• Strong understanding of statistics, machine learning, and quantitative reasoning.
• Proficiency in Python for data analysis and quantitative problem-solving.
• Familiarity with data analysis, experimentation, and data modeling.
• Knowledge of relevant data science tools and libraries, including pandas.
• Ability to identify statistical errors, evaluate methodologies, and assess analytical conclusions.
• Strong written communication skills, including the ability to explain technical and statistical concepts clearly.
• Based in an English-speaking country.

Preferred Qualifications

• Experience evaluating statistical analyses, machine learning approaches, or quantitative solutions.
• Experience designing experiments and interpreting analytical results.
• Familiarity with developing datasets, technical prompts, and reference solutions.
