This position is located in Roy, UT and supports the Sentinel program. The successful candidate will support the Digital Thread System team across the full systems-engineering life cycle, from use-case development through verification. You will collaborate closely with members across the Digital Thread Integrated Product Team and with systems engineers for other Digital Ecosystem IPTs to produce rigorous systems-engineering and design artifacts, working with technical teams and stakeholders to develop and mature a Digital Thread design to provide effective and secure Digital Engineering capability across the SDS Division. Your responsibilities will include engaging user community along with program and government counterparts for use case analysis; defining, allocating, and tracing requirements; ensuring those requirements are accurately represented in the system model; performing functional decomposition and interface definition; and performing verification activities. In addition, you will develop the system architecture using Cameo Enterprise Architecture, modeling behavioral, structural, and analytical aspects of the solution. You will contribute to ongoing requirements development, management, and analysis while establishing unifying modeling techniques, procedures, and processes that enable seamless model development, tool integration, and team collaboration. Specific Duties Include: * Collaborate with Digital Thread Integrated Product Team and with systems engineers for other Digital Ecosystem IPTs to develop rigorous and proper systems engineering and design artifacts. * Use case development, requirements definition, requirements allocation, requirements traceability, functional decomposition, interface definition, verification. * Work with test teams to ensure successful checkout and verification of the system. * Perform user acceptance testing and similar engagements to solicit informal and formal user feedback. * Work with technical teams and stakeholders to develop and mature DTS design as part of the Digital Ecosystem. * 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).
