Review the analytical design, code, and results of Data Scientists for methodological soundness before delivery to the Government. Instruct and mentor Data Scientists and other contract personnel in data science practices, tools, and the Government-furnished technology stack. Develop and maintain analytical standards, business rules, model assumptions, validation procedures, and reproducible methodologies for the data science team, in coordination with the Data Science Advisor.
