MANTECH seeks a mission-focused Data Scientist to support Marine Corps mission engineering and warfighting analysis with onsite work in Stafford, VA.

Responsibilities

• Review, assess, and help validate data science methodologies, analytical models, and workflows supporting mission engineering, warfighting analysis, and capability assessments.
• Evaluate analytical rigor, data quality, assumptions, metrics, and methodological soundness across data-driven studies, models, and decision-support products.
• Use 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.
• Develop objective, analytically supported findings and recommendations that inform experimentation, capability development, requirements development, and senior leader decisions.
• Produce and present technical reports, briefings, visualizations, and other analytic products for government stakeholders, warfighters, engineers, and senior leaders.
• Collaborate across cross-functional teams and, when needed, serve as a program or project lead for small analytic teams supporting mission-focused studies.

Requirements

• Education: 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.
• Alternate: If holding a bachelor’s degree, 4 years of experience are required.
• Experience applying structured analytical methods to complex problems with 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.
• Proficiency with analytical and technical tools: Python, R, MATLAB, SQL, SAS, SPSS, machine learning frameworks, and data visualization platforms.
• Strong written and verbal communication skills, including experience preparing technical reports, analytic briefings, and visualizations for stakeholders and decision-makers.
