Travel: Up to 5% Job ID: 1434 The Role We seek a Mechanical Engineer to manage the complete design of aerospace components and subsystems. You will collaborate with structural, thermal, and control engineers to develop hardware meeting performance, mass, and environmental standards. Your role includes translating concepts from sketches to CAD to space-qualified products within the Thermo-Mechanical Team. Responsibilities 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. Required Qualifications Mechanical Engineering, Aerospace Engineering, or a related engineering discipline 3-6+ years of experience in mechanical design, ideally in aerospace or high-performance hardware. Advanced proficiency in CAD tools (NX, SolidWorks, or equivalent), working with complex assemblies. Strong understanding of materials, tolerancing, and manufacturing processes (CNC, sheet metal, composites, additive manufacturing). Familiarity with design for m
