• Develop SysML diagrams and models, including block definition, internal block, activity, sequence, state machine, requirement, use case, and parametric models.
• Translate customer, mission, and operational needs into structured system requirements and model elements.
• Establish and maintain traceability between requirements, system functions, architecture elements, interfaces, and verification activities.
• Support functional decomposition and allocation of system functions to subsystems and components.
• 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, and 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.
