Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value. Responsibilities Duties & Responsibilities : Operational Readiness Analysis: Analyze, develop, and model reports on worldwide operations and combatant command plans (e.g., fuel feasibility analysis, services' bulk fuel capability readiness) to identify requirements and resolve issues impacting the GBFMD Mission. Modeling & Simulation: Apply Operations Research techniques (including mathematical programming, simulation, optimization, and stochastic modeling) to assess and optimize GBFMD capabilities during assessments, wargaming, and exercise scenarios. Strategic Alignment: Evaluate and ensure the continuous alignment of strategic objectives with logistical capabilities, providing senior leaders with data-driven courses of action (COAs). Methodology Development: Support the development of innovative modeling and measuring techniques; utilize advanced mathematics, statistical methods, systems engineering methods, and operational mathematics techniques. Technical Reporting: Write comprehensive reports documenting complex data analysis, tool design and development, methodology, and test results. Subject Matter Expertise: Provide expert ORSA support and advisory to studies, fuel conferences, exercises, and real-world contingency events. Qualifications Minimum Qualifications:
• DoD SECRET Clearance with eligibility for TS/SCI.
• Bachelor's degree in Operations Research, Systems Engineering, Mathematics, Statistics, or a highly related quantitative discipline.
• Proven experience in Operations Research, Systems Analysis, advanced data analytics, or military logistics modeling.
• Strong proficiency in analytical and data visualization tools such as SQL, Tableau, and Microsoft Excel, Qlik, Databricks, Maven Smart Systems as well as experience with programming languages OR software (e.g., Python,R, GIS, MATLAB, CPLEX).
• Demonstrated understanding of Combatant Command OPLANs and DoD bulk fuel/logistics operations is highly desirable.
• Proven ability to analyze and interpret geospatial data, utilize digital maps, and leverage spatial analysis tools to support decision-making. • Ability to travel within CONUS and OCONUS, approximately 10% of the time. Preferred Qualifications:
• Demonstrated experience with TPFDD analysis and the Joint Operation Planning Process (JOPP).
• Understanding of the petroleum or fuel industry, including market dynamics, supply chain logistics, or regulatory frameworks.
• Proven ability to translate complex data into clear, actionable insights for senior leader decision-making.
• Experience working with DoW, DLA, or USTRANSCOM.
