Summary
The Model-Based Systems Engineer (MBSE) plays a critical role in developing the authoritative Systems Modeling Language (SysML) system model and producing supporting 2D/3D Computer-Aided Design (CAD) documentation for the Joint Integrated Test and Training Center (JITTC-N) flight simulation environment. This position ensures architectural integrity and serves as the custodian of the system’s “single source of truth,” translating high-level requirements into formal models and practical technical drawings for procurement, installation, and maintenance.
Impact
- Maintains architectural consistency across a complex Information Technology (IT) ecosystem, integrating engineering, networking, cyber, audio/visual (A/V), and simulation components.
- Supports governance and change control through model-based impact assessments for the Configuration Control Board (CCB) process.
- Delivers accurate, stakeholder-ready technical products that enable mission-critical training and testing for U.S. Air Force and Department of Defense (DoD) operations.
Key Responsibilities
- System Model Development: Build, manage, and maintain the authoritative SysML model using Cameo Systems Modeler to represent current and future states of flight simulation and IT infrastructure.
- Requirements Management: Translate stakeholder objectives into formal, verifiable system and subsystem requirements within the model.
- Architectural Modeling & Analysis: Model static and dynamic system behaviors; provide formal impact assessments for proposed changes to support CCB governance.
- Technical Drafting & Visualization: Create and maintain 2D/3D technical artifacts—network diagrams, rack elevations, wiring schematics, and facility/component models—using Microsoft Visio and AutoCAD.
- Stakeholder Documentation: Produce tailored architectural views and documentation (e.g., requirements matrices, interface specifications, system diagrams) for program management, engineering teams, and Test & Evaluation (T&E) stakeholders.
- Success in position requires consistent display of the following key abilities:
- Initiative and strong work ethic to work independently, or with a team, or solve challenging problems in a development and prototyping environment.
- Rapid and effective problem solving: identify issues, analyze and interpret data and develop innovative solutions to a variety of complex problems;
- Excellent communication skills to document, develop, and present technical issues so that stakeholders across the organization readily understand the content and their related actions.
- Schedule performance: influencing and collaborating across the organization to result in contract schedule success.
