The Advanced Product Development (APD) Digital Engineering Ecosystem (DEE) subsection is a pioneering systems organization at the forefront of military innovation. This team is responsible for developing, integrating, and deploying the DEE for a CAT 1 New Product Introduction (NPI) in EdisonWorks. This groundbreaking NPI encompasses the design, development, `, testing, and qualification of an advanced engine concept, leveraging cutting-edge technologies to surpass stringent customer requirements. At the core of this initiative lies the DEE, an advanced collaborative platform providing secure, role-based access to a centralized data repository. This comprehensive system serves as the single source of truth for all program-level information, enabling seamless development, coordination, and delivery of engineering products. The DEE integrates state-of-the-art digital tools, optimized processes, innovative methodologies, and robust databases, creating a holistic ecosystem that supports the entire engine lifecycle from conception to sustained operation. The APD Model-Based Requirements and Test (MBRT) engineer will bring model-based principles to requirements and test that revolutionizes the traditional methods of capturing, analyzing, and managing system requirements. The MBRT engineer will work closely with a cross functional team including the DEE team, the program Qual leader, the program test organization and system module leaders.
