Data Scientist

MANTECH seeks a mission-focused, analytically rigorous, and technically strong DATA SCIENTIST to support Marine Corps mission engineering, warfighting analysis, and capability development efforts in STAFFORD, VA.

This is an on-site position supporting government and USMC customers in the evaluation of concepts, capabilities, technologies, and operational approaches through data-driven modeling, simulation, analysis, and technical assessment.

Responsibilities

Include But Are Not Limited To Review, assess, and help validate data science methodologies, analytical models, and workflows used to support mission engineering, warfighting analysis, and capability assessments. Support the evaluation of analytical rigor, data quality, assumptions, metrics, and methodological soundness in data-driven studies, models, and decision-support products.

Apply quantitative, statistical, and computational methods to assess trends, risks, performance, interoperability, capability gaps, and mission impacts across Marine Corps, Naval, and joint systems and concepts. Formulate objective, analytically supported findings and recommendations that inform experimentation, capability development, requirements development, and senior leader decision-making.

Prepare and deliver technical reports, briefings, visualizations, and other analytic products for government stakeholders, warfighters, engineers, and senior leaders.

Collaborate effectively across cross-functional teams and, as needed, serve as a program or project lead for small analytic teams supporting mission-focused studies and related efforts Minimum Qualifications Master’s degree in operations research, data science, statistics, applied mathematics, engineering, computer science, or a related analytical discipline and at least 2 years of experience conducting quantitative analysis, developing or assessing analytical models, or supporting modeling, simulation, and data science efforts.

Candidates with a bachelor’s degree are required to have at least 4 years’ experience. Experience applying structured analytical methods to complex problems involving multiple variables, objectives, constraints, and uncertainties. Experience reviewing or assessing data science methods, analytic workflows, model outputs, or technical approaches for rigor, credibility, and decision-support value.
