Job description

Apply Model-Based Systems Engineering across missile-defense programs - SysML/Cameo modeling, requirements analysis, and architecture.

Clearance: Secret | Level: Senior | Experience: 7+ years | Education: Bachelor's (4-yr) | Location: Huntsville, AL | Type: Full-time

What You'll Do

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

Required Qualifications

• Security Clearance: Active DoD Secret clearance
• Education & Experience: Bachelor degree with 7+ years supporting missile defense or large-scale, complex DoD programs.
• Technical Proficiency: 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).
• Communication: Ability to distill complex system architectures into clear, concise diagrams, technical documentation, and briefings for multidisciplinary stakeholders.

Preferred Qualifications

• 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 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.
