About The Position

Amentum is seeking a Systems Engineer Lead - SysML to support the Space Force Range Contract (SFRC). Position Summary: The candidate will support the Space Force Range Contract (SFRC) Systems Engineering, Integration & Test (SEIT) organization responsible for sustaining and modernizing launch range capabilities at Patrick SFB and Vandenberg SFB. This role applies Model-Based Systems Engineering (MBSE) principles to develop and maintain authoritative system models, manage requirements traceability, support subsystem integration, and enable enterprise-level decision-making across shared range subsystems. The engineer operates within a multi-site, multi-stakeholder environment supporting launch operations, modernization initiatives, and sustainment activities. Essential Functions: Model-Based Systems Engineering (MBSE) Develop, maintain, and mature SysML system models representing functional, logical, and physical architectures. Establish bidirectional traceability between requirements, interfaces, behaviors, and verification artifacts. Author and maintain requirement diagrams, block definition diagrams, internal block diagrams, activity diagrams, sequence diagrams, interface models, and parametric models. Support digital engineering initiatives ensuring models function as authoritative sources of truth. Requirements & Interface Management Decompose customer and enterprise-level requirements into subsystem allocations. Maintain requirements traceability matrices and digital linkages within the model. Support Interface Control Working Groups (ICWGs) and configuration control boards. Identify interface risks and integration gaps across range subsystems. Integration & Test Support Support verification and validation (V&V) planning through model-derived verification mapping. Assist in development of integration test strategies across Eastern and Western Ranges. Provide model-based impact assessments for engineering changes. Support anomaly resolution and structured root cause investigations. Risk & Configuration Management Contribute to risk identification, assessment, and mitigation planning. Support configuration management processes ensuring models remain aligned with baselined documentation. Participate in change management boards and technical governance reviews. Cross-Functional Coordination Interface with government stakeholders, Subsystem Integrated Product Teams (IPTs), cybersecurity, safety, and sustainment teams. Provide technical assessments to SEIT leadership.
