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 materials, and closure of review actions.
Serve as the primary systems engineering interface to the Program Manager, Chief Engineer, and functional organizations (Systems, Software, Hardware, Test, Manufacturing, Supply Chain).
Lead technical reviews and provide well-justified recommendations on technical trades, system architecture, and design decisions to balance performance, safety, and program constraints.
Identify and manage technical risks, issues, and opportunities related to requirements, interfaces, integration, and verification; drive mitigation and “return-to-green” plans when technical performance is at risk.
Collaborate with program planning and CAMs to provide credible inputs to estimates, schedules, and staffing for SEIT scope, and support cost and schedule performance for systems engineering and test activities.
