Spacecraft Structural Analyst

Responsibilities

• Own structural analysis across components, assemblies, and full spacecraft from initial sizing through test and validation
• Develop high-fidelity finite element models and perform analyses (FEA and hand calculations) to evaluate strength, stiffness, stability, and fatigue
• Define structural load cases and environments, including force-limited dynamic loads (random, sine, shock, acoustics)
• Generate margins for metallic and composite structures, including joints and interfaces
• Drive design decisions and architecture through trade studies and analysis insights
• Define and lead structural test campaigns, including vibration and environmental qualification
• Correlate FEM models with test and flight data to improve prediction accuracy
• Generate structural requirements, specifications, and ICDs for components and full spacecraft
• Partner cross-functionally with design, dynamics, manufacturing, and test
• Manage external vendors and third-party analysts

Requirements

• Bachelor’s or Master’s degree in mechanical, aerospace, or related engineering field
• 5+ years of experience as a structural analyst in spacecraft, aerospace, automotive, or similar industries
