Your role includes translating concepts from sketches to CAD to space-qualified products within the Thermo-Mechanical Team.

• →Lead the mechanical design of components, enclosures, and assemblies for space applications.
• →Create detailed 3D CAD models and 2D manufacturing drawings with appropriate GD&T, using CAD software.
• →Improve drive design for weight, stiffness, manufacturability, and ease of integration.
• →Collaborate with other disciplines—mainly thermal, structural analysis, control, electronic, and optics subsystems—to ensure system-level requirements are met.
• →Support integration, manufacturing, and assembly, including interactions with suppliers and participating in design reviews.
• →Procure mechanical parts from COTs or use manufactured components.
• →Assist in prototype builds, fit checks, and environmental testing (vibration, TVAC, thermal cycling).
• →Manage configuration control and documentation throughout the design lifecycle.
• →Contribute to or participate in PDR/CDR reviews and technical trade studies.
