About The Position

MANTECH is hiring a mission-focused Data Scientist to support Marine Corps mission engineering, warfighting analysis, and capability development in Stafford, Virginia. This onsite position supports government and USMC customers by evaluating concepts, capabilities, technologies, and operational approaches through data-driven modeling, simulation, analysis, and technical assessment. The role requires a current, active TS/SCI security clearance. The Data Scientist assesses analytical rigor, data quality, assumptions, metrics, and methodological soundness in studies, models, workflows, and decision-support products. The role applies quantitative, statistical, and computational methods to evaluate trends, risks, performance, interoperability, capability gaps, and mission impacts across Marine Corps, Naval, and joint systems and concepts. It produces objective findings and recommendations and communicates results to government stakeholders, warfighters, engineers, and senior leaders. The position also collaborates across teams and may lead small analytic teams. The position is based in an office environment, with occasional travel to outdoor test and evaluation sites. The projected compensation range is $114,600 to $190,200. Benefits may include health and life insurance, paid time off, holiday pay, short- and long-term disability, retirement and savings, learning and development opportunities, wellness programs, and optional benefit elections, depending on position.

Requirements

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 need at least 4 years of 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.
