• Reviewing AI-generated data science content and the work of trainers and QA personnel.
• Evaluating output quality against established project guidelines and rubrics.
• Providing precise, written feedback to contributors.
• Ensuring all contributors adhere to expected quality standards.
• Assessing work for statistical accuracy, data reasoning, model selection quality, code correctness, reproducibility, metric interpretation, business context awareness, clarity, formatting, instruction adherence, and alignment with project-specific rubrics.
• Identifying recurring quality issues and communicating updates to trainers and QAs.
• Supporting the onboarding process for new contributors.
• Maintaining relevant documentation.
• Assisting in activating contributors who are not working consistently.
• Performing technical reviews of AI-generated data science explanations, code snippets (Python/R/SQL), modeling workflows, statistical interpretations, dashboards, experiment designs, and step-by-step reasoning.
• Handling questions related to statistical assumptions, metrics, model selection, data leakage, validation, coding choices, reproducibility, and rubric interpretation.
• Managing trainer/QA activation by encouraging engagement, tracking follow-ups, and flagging availability issues.
• Reviewing data science outputs for potential risks such as misleading or statistically invalid conclusions.
• Contributing to process improvement by identifying quality gaps and helping to build scalable QA processes.

Qualifications and Experience

Candidates for this role should possess the following qualifications:

• A Bachelor’s, Master’s, or PhD degree in Data Science, Statistics, Computer Science, Machine Learning, Mathematics, Economics, Engineering, or a closely related quantitative field.
• A minimum of 2-5 years of professional experience in data science, analytics, machine learning, statistical modeling, experimentation, data engineering, technical review, or data science education.
• A strong understanding of statistics, probability, data cleaning, exploratory data analysis, feature engineering, supervised/unsupervised learning, model evaluation, experimentation, regression, classification, clustering, and validation methods.
• The ability to evaluate data science content against detailed rubrics and identify issues such as data leakage, flawed assumptions, incorrect metrics, weak methodology, non-reproducible code, or misleading conclusions.
• Proficiency in English, enabling clear communication and the ability to provide detailed technical feedback.
• Experience leading or supporting remote teams of trainers, annotators, analysts, data scientists, engineers, educators, or QAs is strongly preferred.
• Experience with AI training, data annotation, LLM evaluation, data science QA, or rubric-based technical review is a strong plus.

Technical Skills and Tools

Familiarity with the following tools and platforms is preferred:

• Programming languages and libraries such as Python (pandas, NumPy, scikit-learn), R, and SQL.
• Development environments and tools including Jupyter, Git, and MLflow.
• Data visualization tools like matplotlib and dashboarding platforms.
• Big data technologies such as Spark.
• Cloud platforms and general data platforms.
• Collaboration and project management tools including Discord, Google Sheets, Google Docs, trackers, dashboards, GitHub, and project management systems.

Work Arrangement and Application Process

This is a remote, contract-based hourly position. The selection process involves an AI interview, a domain-specific task, and an interview with a recruiter.
