Job description

Avion Solutions Inc., a 100% employee-owned company, is seeking candidates for a Model-Based Systems Engineer (MBSE) to support the Missile Defense Agency (MDA). This position is located in Huntsville, AL.

Job Responsibilities/Duties:

• 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.

• Other duties as assigned.

Required Experience:

• Bachelor's degree with at least seven (7) years supporting missile defense or large-scale, complex DoD programs.

• Demonstrated proficiency withSysML(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.

• Must be a U.S. citizen and have the ability to obtain/maintain a DoW security clearance.

• Must be able to travel up to 15% of the time.

Preferred Qualifications:

• Experience supportingMDA 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 requirement management tools (e.g.,DOORS, Cameo Requirements Plugin) and issue-tracking platforms (Jira, Confluence).

• Experience integrating MBSE models with analytical/simulation environments (e.g., MATLAB/Simulink, Python, or OpenMBEE).

• Familiarity with DoD Systems Engineering processes, CDRLs, and technical baseline governance.
