• Effective collaboration and schedule awareness to support contract milestones and program success.
• Candidates must meet one of the following:
• Bachelor’s degree in a related field and 9 years of relevant experience
• Master’s degree in a related field and 7 years of relevant experience
• Doctorate (Ph.D.) or Juris Doctor (J.D.) in a related field and 4 years of relevant experience
• High school diploma or equivalent and 13 years of relevant experience
• Hands‑on proficiency with SysML and Cameo Systems Modeler.
• Ability to build, manage, and maintain complex system models end‑to-end.
• Experience producing and maintaining 2D/3D technical drawings using Microsoft Visio and AutoCAD.
• Ability to generate architecture products for diverse engineering and program stakeholders.
• Understanding of network architecture (TCP/IP, routing, switching), server infrastructure, virtualization, and cybersecurity boundaries.
• Must be a U.S. Citizen.
• Must have held an active Department of Defense (DoD) Top Secret clearance within the last 24 months.
• Ability to obtain and maintain DoD TS/SCI and applicable Special Access Program (SAP) / Special Access Required (SAR) clearances.

• Familiarity with the Department of Defense Architecture Framework (DoDAF) or Unified Architecture Framework (UAF).
• Exposure to cybersecurity principles and the Risk Management Framework (RMF).
• MBSE‑related certification such as the OMG‑Certified Systems Modeling Professional (OCSMP).
• Experience scripting within Cameo to automate model validation or report generation.
• Experience supporting integration labs, test events, or complex system deployments.

Responsibilities

• System Model Development: Build, manage, and maintain the authoritative SysML model using Cameo Systems Modeler, representing both current and planned system states.
• Requirements Management: Translate stakeholder needs into formal, verifiable system and subsystem requirements within the model.
• Architectural Modeling & Analysis: Model system structure, behavior, interfaces, and interactions; generate formal assessments to support CCB decision‑making.
• Technical Drafting & Visualization: Create and maintain 2D/3D technical materials—including network diagrams, rack elevations, wiring drawings, and facility/component layouts—using Microsoft Visio and AutoCAD.
• Stakeholder Documentation: Produce tailored architectural views, reports, matrices, and specifications to support program management, engineering teams, cybersecurity, and Test & Evaluation (T&E) stakeholders.
