About You:

You are a senior systems thinker and mission engineer with a strong foundation in applied systems engineering. You understand how people, processes, technologies, interfaces, and operational constraints interact to produce mission outcomes. You translate complex defense and national security problems into mission threads, requirements, architectures, analytical models, and evidence-based recommendations.

You are a self-starter who turns broad sponsor guidance into a practical work plan and delivers substantive results with limited day-to-day direction. You engage directly with government stakeholders, ask informed questions, communicate technical findings clearly, and follow through on commitments. You can move between mission-level analysis and practical systems engineering while recognizing when specialist support or a sponsor decision is needed.

You bring hands-on M&S-development capabilities and can quickly turn a conceptual model or framework into a functioning prototype. You use Python and approved cloud environments such as AWS, or can rapidly become productive in them by building on demonstrated development experience. You apply these skills to agentic modeling, simulation, and wargaming, critically evaluating model logic, generated code, assumptions, and outputs rather than accepting them at face value.

Position Overview:

VT-ARC is seeking a Senior Systems & Mission Engineer (Modeling, Simulation & Wargaming) to support mission engineering, analytical wargaming, modeling and simulation, and related systems engineering efforts within the Decision Science Division (DSD).

This opportunity focuses on contested logistics, maritime sustainment, national mobilization, force generation, reconstitution, and defense industrial-base challenges. The role develops and refines automated analytical workflows, connecting structured mission artifacts and engineering requirements with simulation, agentic AI-assisted analysis, and traceable decision products.

This hands-on senior technical contributor also supports conventional systems engineering assignments and may serve as the primary developer for defined prototypes and proofs of concept. The individual will independently design, code, test, and demonstrate working models and analytical capabilities while collaborating with data scientists, senior engineers, AI engineers, and developers. As capabilities advance toward production, the role will work with additional developers and specialists on software hardening, scaling, deployment, and sustainment, while maintaining continuity of mission requirements and analytical validation.

This position is a contingency hire based on a contract award expected to begin execution on or about November 01 st , 2026.

Duties/Responsibilities:

• Translate sponsor questions and operational needs into mission objectives, study boundaries, requirements, assumptions, and measures of performance and effectiveness.
• Develop mission decompositions, mission threads, operational architectures, concepts of operations (CONOPS), concepts of employment (CONEMPs), and scenarios; organize linked mission artifacts, dependencies, constraints, and measures.
• Develop and maintain system requirements, architectures, interface definitions, traceability, and integration and verification/validation plans; assess technical evidence, proposed changes, interoperability, and risk.
• Define conceptual models, decision logic, input data, constraints, outputs, and evaluation criteria; translate this structure into working prototypes and implementation specifications that support testing, collaboration, and further development.
• Design, code, test, debug, document, and demonstrate proof-of-concept models, simulation components, data integrations, and analytical applications. Take defined prototypes from an initial concept to a working implementation and iteratively refine them based on evaluation and sponsor feedback.
• Use Python and supporting coding tools to prepare data, automate analytical workflows, configure and run models, and examine results. Conduct trade studies and sensitivity analyses; check assumptions, uncertainty, and reproducibility.
• Implement, configure, and evaluate human-supervised agentic modeling and AI-assisted analytical workflows, including task decomposition, agent and tool orchestration, approved-data retrieval, experiment setup, and result interrogation. Verify generated code and findings against requirements, source evidence, and reference cases.
• Use approved AWS environments to configure and run prototype applications, execute scripts or models, manage analytical data, and retrieve results; coordinate infrastructure, access, and security requirements with specialists.
• Develop objectives, scenarios, adjudication or evaluation logic, and data-collection plans for wargames and tabletop exercises; support facilitation and synthesize findings with the study team.
• Maintain traceability across mission artifacts, AI/ML-assisted analysis, simulation inputs, assumptions, and findings. Prepare version-controlled code, test cases, model documentation, and implementation notes to support reproducibility, technical review, and transition of viable prototypes to production teams.
• Engage directly with government sponsors and mission stakeholders to clarify requirements, facilitate workshops and expert elicitation, demonstrate working prototypes and analytical tools, and brief findings, limitations, and recommendations.
• Independently plan and execute assigned technical work, resolve routine issues, identify risks and dependencies early, and elevate decisions appropriately. Produce engineering artifacts and decision briefs, provide peer review, and coordinate deliverables with program leadership.

Required Education, Certification, Skills, Capabilities:

• 10+ years of progressively responsible experience in systems engineering, mission or operational analysis, or related technical work, including direct support to defense or national security missions and independent responsibility for technical deliverables.
• Demonstrated application of systems engineering methods: requirements, architectures, interfaces, traceability, integration and verification/validation planning, and assessment of technical evidence. Ability to produce usable engineering artifacts beyond mission-analysis studies; a prior Systems Engineer title is not required.
• Demonstrated ability to develop, test, debug, document, and maintain software supporting analytical, modeling, simulation, or engineering applications. Ability to turn requirements and model logic into a functioning prototype, not solely configure existing tools or direct development by others.
• Working proficiency in Python, or proficiency in another relevant programming language with demonstrated ability to quickly become productive in Python. Candidates must already be able to write, modify, troubleshoot, and test code; prior development experience and successful technical learning are required.
