Responsibilities

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