## Description

The Systems Engineer III serves as a senior technical contributor for NSWC Crane Code GXP and SSP model-based systems engineering. This Key Personnel position leads complex systems-engineering, requirements, architecture, model integration, verification, and simulation activities that preserve technical traceability and configuration control across Strategic Weapon System acquisition and modernization programs., Lead development, integration, maintenance, and technical review of SysML Descriptive System Models, Integrated Verification Models, interface models, and system-level simulation artifacts.

Guide requirements elicitation, decomposition, allocation, traceability, validation, and verification across multiple systems, technical branches, and acquisition stakeholders.

Apply SSP systems-engineering policies, modeling standards, ontology profiles, and integrated modeling and simulation standards to program technical baselines.

Develop and evaluate systems architectures, design alternatives, interfaces, verification strategies, engineering risks, and lifecycle technical plans.

Coordinate model and simulation integration with SSP offices, NSWC Crane organizations, prime contractors, and subsystem teams; identify inconsistencies and drive issues to resolution.

Lead technical support for system integration, simulation, hardware-in-the-loop and software-in-the-loop events, test analysis, and evaluation of requirements-satisfaction evidence.

Support configuration and technical-data management for documentation, models, simulations, verification reports, and established technical baselines.

Prepare and present model views, analyses, recommendations, and technical evidence for systems-engineering reviews, working groups, and acquisition milestones.
