About The Position

NDI Engineering is seeking a Systems Engineer to serve as a technical lead for the Naval Surface Warfare Center (NSWCPD). This role is pivotal in transitioning complex Submarine Hull, Mechanical, and Electrical (HM&E) systems from document-based engineering to a Model Based Engineering (MBSE) environment. You will lead the development and maintenance of enterprise-level architectures, ensuring that safety, cybersecurity, and mission requirements are digitally integrated across the full system lifecycle—from initial design through sustainment. The Systems Engineer will serve as a technical MBSE lead supporting system development, analysis, risk management, requirements management and validation, delivery certification and life cycle support. The role focuses on the application of system modeling ensuring architectural coherence, safety, cybersecurity, and mission requirements are integrated across the system lifecycle. Position involves using digital models to manage and integrate system engineering activities, ensuring traceability, compliance, and performance across the product lifecycle and blends systems engineering, modeling, and collaboration across technical disciplines. The role is an in-person in the Philadelphia area, supporting in-service and new submarine systems at NSWCPD. The position is part of NDI Engineering’s mission to enable design, test and evaluation, acquisition, engineering, systems integration, and life-cycle savings with cybersecurity and logistics integration.
