Northrop Grumman Mission Systems is seeking a Senior Principal Systems Engineering, Integration & Test (SEIT) Lead in Woodland Hills, CA.

This role leads the systems engineering and verification effort for airborne navigation systems with a strong emphasis on the correct development, control, integration, and verification of system requirements. You will partner closely with Program Managers, Chief Engineers, product owners, and discipline functional engineering leadership to ensure the system design meets customer needs and is rigorously validated and verified.

This is a full time, on site role in Woodland Hills, CA. What You’ll Get to Do The SEIT Lead is accountable for the overall technical integrity and rigor of the systems engineering effort on the program. This includes ownership of requirements development and management, integration and test strategy, and verification and validation (V&V) planning and execution, with secondary responsibility for supporting program cost and schedule performance for SEIT scope.

Key responsibilities: Lead systems engineering, integration, and test activities across the full program lifecycle (capture through delivery) for airborne navigation systems. Own and maintain the system requirements baseline, including development, decomposition, allocation, traceability, and change control from customer requirements through subsystem and component levels. Use IBM Rational DOORS (or equivalent requirements management tools) to manage requirements, maintain traceability, and ensure configuration control of the requirements baseline.

Ensure requirements are clear, verifiable, and consistent, and that they are implemented and verified through test, analysis, inspection, and/or demonstration. Develop, maintain, and execute the Systems Engineering Management Plan (SEMP), integration and test strategy, and verification cross-reference matrices (VCMs) / requirements verification matrices (RVMs). Lead the planning and execution of integration and test activities at subsystem and system levels, including lab, hardware-in-the-loop, and flight/field test environments as applicable.

Ensure engineering execution meets the applicable level of rigor and aligns with standards including MIL STD 810 for environmental qualification, DO 178 and MIL STD 882 for safety critical software development and safety analyses, and DO 229 for GPS integrity certification. Lead major system technical reviews (e.g., SRR, PDR, CDR, TRR) with senior internal leadership and customer stakeholders, including preparation of technical content, presentation material
