About The Position

MTSI is seeking a Senior Defense Technologist – Modeling & Simulation (SDT-M&S) to serve as a senior technical architecture integrator within OUSW(R&E), providing advanced modeling, simulation, and analytic architecture support. The role focuses on building an integrated analytical environment (e.g., models, data structures, workflows, assumptions, and governance) that supports evaluation of new capabilities and investment decisions. Your work will shape the analytical backbone MEIA uses to improve how the Department evaluates new concepts and capabilities. By developing a coherent MEIA M&S architecture, you will enable more timely, evidence-based acquisition decisions and strengthen mission focused capability integration. This position is located in the National Capital Region (NCR). You’ll be a great fit for this role if you can think architecturally—connecting models, tools, data, workflows, and mission engineering processes into a coherent whole; enjoy working in environments that require both technical precision and operational awareness; excel at designing structures that improve analytical rigor, transparency, and repeatability; communicate complex architectural ideas clearly to both technical and non-technical audiences; and are energized by contributing to acquisition reform through better analytical foundations.

Requirements

• Minimum 15 years of experience with emphasis on: Developing or integrating modeling and simulation architectures, analytical frameworks, or system-of-systems analytical environments.
• Applying mission engineering, operations research, or systems engineering methods to evaluate military capabilities.
• Leading complex analytical or technical integration efforts within classified DoW environments.
• Designing data structures, workflows, or toolchains supporting quantitative mission analysis.
• Translating operational concepts and mission level problems into structured analytical constructs.
• Supporting capability development, concept maturation, or acquisition processes with analytical products.
• Producing high-quality technical documentation and senior-level briefings.
• An active Top Secret (TS) security clearance (with SCI and SAP/CAP eligibility) is required.

Nice To Haves

• Experience transitioning efforts across the lifecycle.
• Military Service Staff/Headquarters, Joint Staff, or similar level analytical experience.
• Demonstrated ability to connect tactical, operational, and strategic considerations into coherent recommendations.
• Experience architecting M&S ecosystems that integrate disparate models, tools, datasets, or mission engineering products.
• Strong systems engineering grounding, especially in decomposition, requirements development, and architecture modeling.
• Knowledge of enterprise M&S frameworks, standards, and best practices.
• Demonstrated ability to work across technical and operational communities to align processes and architectures.
• Exceptional communication and collaboration skills in integrated government–contractor teams.
• Strong quantitative reasoning and ability to collaborate with M&S and campaign analysis personnel.

Responsibilities

• Support the development and maturation of MEIA’s M&S architecture, including frameworks, taxonomies, data standards, and integration patterns.
• Define and document architectural requirements derived from mission engineering objectives, operational needs, and analytical workflows.
• Identify, integrate, and align analytical tools, modeling environments, and data sources supporting MEIA’s mission engineering processes.
• Ensure M&S architectural components support defensible decision-making, traceability of assumptions, and repeatable analysis.
• Develop model governance structures, version control approaches, and analytic quality standards.
• Collaborate with technical teams to align architecture components with operational constructs, mission threads, and capability concepts.
• Lead technical reviews of architecture components, integration plans, model assumptions, and data structures.
• Support scenario development, mission engineering decomposition, and architecture to analysis mapping.
• Communicate architectural insights, integration findings, and modernization recommendations to senior DoW leadership.
• Maintain compliance with all classification, data handling, and disclosure requirements.
