This Systems Engineer position will support activities including use case development, requirements definition / allocation, functional decomposition, interface definition, verification & validation, and requirements traceability. Collaborate with program IPT counterparts to develop supporting systems engineering and design artifacts. Work with both technical teams and stakeholders to develop and mature architecture content of large programs design. Help develop and incorporate the appropriate requirements for the system and ensure that they are properly represented in the model. Develop systems architecture using Cameo Enterprise Architecture (behavioral, structural, analytical). Contribute to system requirements development, management, and analysis. Develop unifying model techniques, procedures, and processes (for model development, tool integration, and team integration).
