MTSI is seeking a Senior Defense Technologist - Modeling & Simulation. The SDT-M&S will serve as a senior Mission Engineering Modeler supporting the Office of the Under Secretary of War for Research & Engineering (OUSW(R&E)) Mission Engineering Integration Activity (MEIA). This position supports mission-focused analysis of future military capabilities, kill chains, kill webs, and advanced concepts through the application of first-principles physics, mission engineering, modeling and simulation, and digital prototyping.
The successful candidate will operate at the intersection of operational analysis, systems engineering, and software-based modeling and simulation. Daily activities will include developing and executing advanced mission-level analyses, designing physics-based simulation capabilities, constructing digital prototypes, supporting campaign and mission assessments, and providing technical recommendations to senior government leadership.
Daily responsibilities include:- Developing and maintaining high-fidelity AFSIM models, scenarios, and custom C++ plug-ins.
- Creating physics-based models of sensors, communications systems, weapons, autonomy, space systems, and electronic warfare capabilities.
- Translating operational problems, mission threads, and kill chains into executable simulation models and mission engineering analyses.
- Supporting mission characterization activities through collaboration with operational planners, intelligence analysts, technologists, and mission engineers.
- Conducting mission-level trade studies, sensitivity analyses, and Design of Experiments (DOE) to assess capability effectiveness and mission outcomes.
- Integrating data, models, architectures, and simulation outputs into a repeatable mission engineering framework.
- Supporting development of mission architectures, mission engineering threads (METs), kill web architectures, and system-of-systems analytical products.
- Producing clear, defensible technical findings and recommendations for senior government decision makers.
- Serving as a trusted technical advisor supporting OUSW(R&E) priorities, technology investment decisions, experimentation activities, and acquisition initiatives.
