The RSE will lead and coordinate cross-functional Systems Engineering teams in the development, integration, and assessment of system-level technical solutions supporting the evolving Missile Defense System (MDS). The RSE will apply Systems Engineering principles, Model-Based Systems Engineering (MBSE), architecture development, requirements analysis, interface definition, and technical trade studies to support the development of incremental MDS capabilities. The engineer will evaluate system-level impacts associated with current and emerging threats, including ballistic, aero-maneuvering, hypersonic/glide, and countermeasure-enabled threats. The successful candidate will work across multiple engineering disciplines and MDS elements to develop system-of-systems architectures, requirements, interfaces, and technical solutions. The RSE will use the MBSE environment to evaluate functional behavior, architectural alternatives, system/component trades, and requirements relationships while maintaining traceability from system-level requirements through element-level implementation and verification., * Lead and coordinate cross-functional Systems Engineering teams in the development of system-level technical solutions for MDA. * Develop and evaluate system-of-systems architectures to support current and future MDS capabilities. * Apply Systems Engineering principles to assess architectural alternatives and identify technical impacts, dependencies, and integration considerations. * Utilize Model-Based Systems Engineering (MBSE) tools and methodologies to model system behavior, architecture, requirements, interfaces, and relationships. * Perform functional and behavioral analysis to evaluate system responses to conventional and advanced threats. * Support system-level analysis for threat classes including: + Ballistic missile threats + Aero-maneuvering threats + Hypersonic/glide threats + Advanced maneuvering threats + Countermeasure and counter-countermeasure environments + Other emerging or evolving threat capabilities * Develop and analyze system-level requirements supporting incremental MDS capability development. * Lead system/component trade studies and technical analyses to evaluate alternative approaches and determine impacts to system performance, architecture, interfaces, requirements, and integration. * Develop, assess, and maintain system-level interfaces and interface definitions across MDS elements and components. * Develop and maintain architectural models, functional models, requirements relationships, and system-level technical products within the MBSE environment. * Lead the development of Change Notices (CNs) to MDA system specifications. * Develop and update functional, interface, and performance requirements based on evolving system capabilities, architectures, operational concepts, and technical assessments. * Establish and maintain traceability from system-level requirements through element-level requirements and verification activities. * Identify requirements gaps, inconsistencies, conflicts, and architectural impacts and coordinate resolution across affected engineering organizations. * Collaborate with MDA, Element Program Offices, Systems Engineering teams, test organizations, and other stakeholders to develop technically sound and executable system solutions. * Assess the impact of proposed changes to system architecture, requirements, interfaces, and element capabilities. * Support requirements decomposition and allocation from the system level to subordinate elements and components. * Ensure system-level requirements and architecture are consistent with functional behavior, operational needs, technical constraints, and system interfaces. * Develop and deliver technical products including technical briefings, architecture products, requirements products, trade studies, CNs, and engineering analyses. * Present technical findings, recommendations, and proposed system changes during internal engineering and MDA stakeholder reviews. * Facilitate technical discussions among multidisciplinary engineering teams and drive issues toward resolution. * Support technical reviews, requirements reviews, architecture reviews, and other MDA Systems Engineering forums. * Maintain awareness of emerging MDS technologies, threat developments, and engineering approaches that may affect system architecture and requirements. * Work independently while effectively coordinating activities across a multi-disciplinary and geographically distributed engineering organization.
