About The Position

Valkyrie Enterprises is seeking a Model-Based Systems Engineer in Huntsville, Alabama, supporting the Targets and Countermeasures program office. The position applies systems engineering principles within a digital engineering framework to create, analyze, and maintain system architecture models. The engineer collaborates with government leads, prime contractors, and cross-functional engineering teams to trace requirements, model behavioral and structural architectures, and support technical baseline reviews. Employment is contingent upon prime contractor approval. The role develops and maintains SysML models capturing system behavior, structure, interfaces, and operational requirements across MDA programs. It supports end-to-end requirements traceability, digital engineering integration, milestone reviews, architectural trade studies, interface analysis, and configuration management of models. Travel is minimal, at 10% or less.

Requirements

Bachelor’s degree.
At least 7 years supporting missile defense or large-scale, complex DoD programs.
Demonstrated proficiency with SysML and core systems engineering frameworks, including DoDAF and UAF.
Hands-on experience with industry-standard MBSE modeling tools such as Cameo Systems Modeler/Cameo Enterprise Architect, MagicDraw, or Sparx Enterprise Architect.
Ability to distill complex system architectures into clear, concise diagrams, technical documentation, and briefings for multidisciplinary stakeholders.
Active Secret clearance and ability to maintain it.
If travel by domestic flight or access to secure federal facilities or military bases is required, ability to obtain appropriate identification credentials, such as REAL ID, by the start of the position and maintain them.

Nice To Haves

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

Responsibilities

Develop and maintain SysML system models that capture behavior, structure, interfaces, and operational requirements across MDA programs.
Map system-level and component-level requirements to architecture artifacts, maintaining end-to-end traceability, verification matrices, and baseline integrity.
Support MDA Digital Engineering initiatives by linking MBSE models with external tools, simulations, and data repositories.
Prepare and present model-centric artifacts for program milestone reviews, including SRR, PDR, CDR, and 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 under program data management standards.
