<p>Government Reference Architecture (GRA) Development for Ground Segments Lead the development and documentation of the Government Reference Architecture (GRA) for ground segments, ensuring alignment with Air Force strategic goals and objectives. Define architectural principles, standards, and guidelines to promote interoperability, modularity, severability, and scalability across future adopting platform ground segments. Analyze existing and emerging ground segment architectures, technologies, and standards to inform the GRA development process. Collaborate with stakeholders from various organizations (e.g., program offices, system integrators, industry partners) to gather requirements and ensure the GRA meets their needs. Champion and assist with the adoption of the GRA within the Air Force and broader DoD community. Develop solutions and recommendations to improve data exchange, communication protocols, and functional integration. Evaluate the impact of new technologies and standards on ground segment interoperability. Apply Model-Based Systems Engineering (MBSE) principles and tools to create digital models of the GRA and its key interfaces, simulating system integration and interoperability. Develop and maintain system models to support trade studies, architectural analysis, and validation of GRA principles. Develop and deliver comprehensive technical documentation for the GRA, including architectural diagrams, interface specifications, and implementation guidelines. Work closely with cross-functional teams, including system integrators, software developers, cybersecurity professionals, and acquisition personnel. Mentor junior engineers on best practices in ground systems architecture and (where applicable) MBSE methodologies related to reference architectures. Act as a trusted advisor to government stakeholders, providing guidance on how the GRA can improve program outcomes and mission readiness. Extensive knowledge of ground systems architecture principles, technologies, and standards. Deep understanding of interoperability challenges and solutions in complex systems. Experience developing and documenting architectural reference models or frameworks. Proficiency in MBSE tools, techniques, and modeling languages (e.g., SysML) is highly desirable. Comprehensive knowledge of system development lifecycles, DoD acquisition processes, and MIL-STDs. Strong analytical and problem-solving skills to evaluate complex systems and optimize interoperability. Excellent communication, presentation, and interpersonal skills. Ability to work under pressure, manage competing priorities, and meet strict deadlines in a classified environment. Security Clearance: Active Top Secret clearance with eligibility for Sensitive Compartmented Information (SCI). Education: Bachelor's Degree in Systems Engineering, Computer Science, Aerospace Systems, or related field. Advanced degrees are preferred, but equivalent military or professional experience may be considered. Minimum of 5 years of experience in systems engineering, with a focus on ground systems architecture and standards. Experience developing or working with architectural reference models or frameworks is highly desired. Experience applying MBSE methodologies in DoD environments is preferred, especially in the context of architecture modeling. Proficiency in MBSE tools such as Cameo Systems Modeler, MagicDraw, or Enterprise Architect is highly desirable.</p>
