Conduct engineering analysis to evaluate system performance, interoperability, technical risks, and compliance with established requirements and operational objectives
Support the integration of space, ground, and supporting infrastructure systems to ensure compatibility, operational effectiveness, and mission readiness
Provide technical expertise in space system architectures, satellite and ground segment design, sensor systems, communications, and space battle management and control capabilities
Support Research, Development, Test, and Evaluation (RDT&E) activities, including technical reviews, engineering assessments, test planning, and evaluation of emerging technologies
Develop and maintain systems engineering artifacts consistent with applicable Joint Capabilities Integration and Development System (JCIDS) and Department of Defense Architecture Framework (DoDAF) processes
Perform configuration management, engineering change analysis, and technical impact assessments to evaluate proposed system modifications and capability enhancements
Coordinate with System Program Offices (SPOs), Program Management Offices (PMOs), Government stakeholders, and technical teams to support system development, capability delivery, and acquisition objectives
Assess and align technical requirements, engineering activities, and program priorities with Planning, Programming, Budgeting, and Execution (PPBE) processes supporting OTTI initiatives
Support technical planning, program reviews, engineering briefings, and decision-support activities to communicate system performance, technical risks, and recommended solutions
Provide engineering support for system deployment, operational integration, sustainment, and continuous improvement of space test and training materiel systems
Collaborate with multidisciplinary engineering teams to resolve technical challenges, manage system dependencies, and ensure alignment with USSF mission requirements
