Job description

Model-Based Systems Engineer (MBSE)

Huntsville, AL | Active Secret Clearance

Your expertise. Our nation's defense.

At Banner Defense, you're more than a name on a contract. As a Service-Disabled Veteran-Owned Small Business, we know what it means to serve, and we build our team around people who take pride in protecting those who protect us. Here, your work directly supports the warfighter, your voice is heard, and your growth matters.

THE OPPORTUNITY

Banner Defense is in search of a Model-Based Systems Engineer (MBSE) to support the Targets and Countermeasures program office of the Missile Defense Agency (MDA). In this role, you will apply systems engineering principles within a digital engineering framework to create, analyze, and maintain system architecture models. You will collaborate with government leads, prime contractors, and cross-functional engineering teams to trace requirements, model behavioral and structural architectures, and support technical baseline reviews.

WHAT YOU'LL DO

• Develop and maintain descriptive system models using SysML to capture system behaviors, structure, interfaces, and operational requirements across MDA programs
• Map system-level and component-level requirements directly to architecture artifacts, ensuring end-to-end traceability, verification matrices, and baseline integrity
• Support the implementation of MDA Digital Engineering initiatives by linking MBSE models with external tools, simulations, and data repositories
• Assist in preparing and presenting model-centric artifacts for major program milestone reviews (e.g., SRR, PDR, CDR, CCBs)
• Conduct architectural trade studies, analyze interface definition documents (IDDs/ICDs), and model system interfaces to identify gaps and resolve integration risks
• Maintain version control and configuration baseline compliance for SysML models in accordance with program data management standards.

WHAT YOU'LL BRING

• Bachelor's degree and 7+ years of experience supporting missile defense or large-scale, complex DoD programs
• Active DoD Secret security clearance, which requires U.S. Citizenship
• Demonstrated proficiency with SysML (Systems Modeling Language) and core systems engineering frameworks (DoDAF, UAF)
• Hands-on experience with industry-standard MBSE modeling tools (e.g., Cameo Systems Modeler/Cameo Enterprise Architect, MagicDraw, Sparx Enterprise Architect)
• Ability to distill complex system architectures into clear, concise diagrams, technical documentation, and briefings for multidisciplinary stakeholders
• Some travel is required.

PREFERENCE IF YOU HAVE

• Experience supporting MDA programs (e.g., Targets and Countermeasures, Ground-Based Midcourse Defense, THAAD, Aegis BMD, or C2BMC)
• OMG-Certified Systems Modeling Professional (OCSMP) certification (Fundamental, Intermediate, or Advanced)
• Working knowledge of requirements management tools (e.g., DOORS, Cameo Requirements Plugin) and issue-tracking platforms (Jira, Confluence).
