ModelBased Systems Engineer

Input Technology Solutions; Huntsville (AL); On-site; USD 110,000 - 165,000; Full time

Job summary

Input Technology Solutions seeks a Model-Based Systems Engineer (MBSE) to support the Missile Defense Agency’s Targets and Countermeasures program office. You will develop SysML-based models, trace requirements, and support technical baseline reviews with government leads and prime contractors.

Ideal candidates bring 7+ years in DoD programs, an active DoD Secret clearance, and MBSE tool experience (Cameo, MagicDraw, Sparx).

Qualifications

• Active DoD Secret clearance.
• Bachelor's degree in STEM.
• 7+ years supporting missile defense or large DoD programs.
• Proficient with SysML and DoDAF/UAF.
• Experience with MBSE tools (Cameo, MagicDraw, Sparx).

Responsibilities

• 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 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 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 per program data management standards.

Job description

Input Technology Solutions is seeking 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 Be Doing:

• 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.

What Required Skills You'll Bring:

• 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.

What Desired Skills You'll Bring:

• 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.
