• Support satellite mechanical/structural and payload development across both non-recurring engineering (NRE) and recurring programs. • Create and manage full spacecraft CAD assemblies, including skeleton models, subsystem interfaces, and flight hardware. • Develop and maintain mass properties databases for all satellite and launch configurations. • Implement CAD-based controls to validate mass properties tracking. • Develop and maintain interface control drawings (ICDs), detailed manufacturing drawings, assembly drawings, and Bills of Material (BOM). • Perform mechanical/structural subsystem and payload trade studies to optimize system architecture for performance, mass, cost, and manufacturability. • Support preparation of preliminary and detailed mechanical designs. • Provide technical support to procurement, production, assembly, and testing for spacecraft structures and hardware. • Collaborate with multidisciplinary engineering teams to ensure seamless integration of mechanical and structural designs into the spacecraft system.
