## Description

* Serve as the Lead System Architect for MBSE, providing technical leadership, direction, and oversight for system modeling activities across the program.
 * Develop and maintain the program's MBSE strategy, modeling approach, architecture, governance, and roadmap in alignment with program systems engineering objectives and Digital Engineering initiatives.
 * Define and maintain the overall model architecture, including model organization, decomposition, viewpoints, relationships, naming conventions, modeling standards, and modeling patterns.
 * Lead development and maintenance of integrated system models representing system architecture, requirements, behaviors, functions, interfaces, verification relationships, and other elements of the technical baseline.
 * Establish and maintain traceability between mission needs, operational capabilities, system architecture, requirements, interfaces, verification activities, and supporting engineering artifacts.
 * Define the approach for integrating and, where appropriate, federating models and engineering data produced by government organizations, development contractors, support contractors, and other stakeholders.
 * Evaluate contractor-developed models and modeling approaches for consistency with program architecture, requirements, technical baseline objectives, and established modeling standards.
 * Manage the configuration of a Teamwork Cloud database employing multiple Project Usages.
 * Manage the data connectivity between Cameo System Modeler and IBM Rational DOORS.
 * Work closely with requirements engineers to establish and maintain relationships and traceability between modeled architecture and authoritative system requirements.
 * Work with interface engineering teams to ensure system interfaces, logical and physical connections, exchanges, and dependencies are consistently represented within the model.
 * Work with verification and test organizations to incorporate verification methods, relationships, evidence, and system behavior into the modeling environment as appropriate.
