Job description

Contingent upon prime contractor approval

Purpose:

• Valkyrie Enterprises has need for a Model-Based Systems Engineer in Huntsville, AL working in a Targets and Countermeasures program office.
• 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.

Job Description:

• 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

Qualifications:

• Must have a Bachelor’s degree with at least 7+ years supporting missile defense or large-scale, complex DoD programs.
• Must have demonstrated proficiency with SysML (Systems Modeling Language) and core systems engineering frameworks (DoDAF, UAF).
• Must have hands‑on experience with industry‑standard MBSE modeling tools (e.g., Cameo Systems Modeler / Cameo Enterprise Architect, MagicDraw, Sparx Enterprise Architect).
• Must have the ability to distill complex system architectures into clear, concise diagrams, technical documentation, and briefings for multidisciplinary stakeholders.

Desired Qualifications:

• Experience supporting MDA programs (e.g., Targets and Countermeasures, Ground-Based Midcourse Defense, THAAD, Aegis BMD, or C2BMC), preferred.
• OMG‑Certified Systems Modeling Professional (OCSMP) certification (Fundamental, Intermediate, or Advanced), preferred.
• Working knowledge of requirement management tools (e.g., DOORS, Cameo Requirements Plugin) and issue‑tracking platforms (Jira, Confluence), preferred.
• Experience integrating MBSE models with analytical/simulation environments (e.g., MATLAB/Simulink, Python, or OpenMBEE), preferred.
• Familiarity with DoD Systems Engineering processes, CDRLs, and technical baseline governance, preferred.

Security Requirements:

• Must have an Active Secret clearance and the ability to maintain it.

Travel Requirements:

• If position requires travel by domestic flight or access to secure federal facilities/military bases, candidate must be able to obtain (by start of position) and maintain appropriate identification credentials, such as REAL ID. (More information regarding REAL ID can be found: https://www.dhs.gov/real-id )

Physical Requirements:

• Remaining in a stationary position, often standing, or sitting for prolonged periods
• Able to sit and work on a computer for long periods of time
• Moving about to accomplish tasks or moving from one worksite to another
• Communicating with others to exchange information
