Model and analyze interfaces, data flows, system interactions, and dependencies across subsystems and external systems.
Develop system architectures and digital engineering artifacts to support concept development, design decisions, integration, and system lifecycle activities.
Support system-level trade studies and technical analyses using system models to evaluate design alternatives and system behavior.
Collaborate with systems, software, hardware, cybersecurity, network, integration, and test engineers to ensure models accurately represent the system.
Support system integration, verification, and validation by using system models to identify requirements, interfaces, dependencies, and verification relationships.
Develop and maintain MBSE modeling standards, modeling conventions, reusable model elements, and architecture frameworks.
Maintain model integrity, consistency, configuration, and version control throughout the system lifecycle.
Identify inconsistencies, gaps, and conflicts within system requirements, architectures, interfaces, and models.
Support technical reviews, architecture reviews, requirements reviews, design reviews, and customer technical interchange meetings.
Generate technical documentation, architecture views, reports, and other engineering artifacts from system models.
Support integration of MBSE models with requirements management, simulation, test, configuration management, and other engineering tools.
Apply digital engineering and digital thread concepts to improve the management and exchange of engineering information.
Support the implementation and adoption of MBSE processes, tools, and best practices across engineering teams.
Automate modeling, analysis, reporting, or other engineering processes using scripting or programming languages when applicable.
Ensure MBSE activities and deliverables comply with applicable customer requirements, industry standards, modeling practices, and program processes.
