About The Position

The Structural Analysis Engineer is responsible for substantiating spacecraft primary and secondary structures through finite element analysis and first-principles hand calculations. This role owns structural verification activities, including stress, deflection, stability, and margin of safety assessments that support design and qualification decisions. The position works closely with design, manufacturing, and test teams to ensure structural integrity is maintained throughout development.

Requirements

• 2–5 years of experience in spacecraft structural analysis, primary structures, or structural substantiation roles
• Experience performing stress, deflection, buckling, and margin of safety assessments using FEM and hand calculations
• Proficiency developing and maintaining structural finite element models using FEMAP/Nastran or Siemens Simcenter 3D
• Experience substantiating metallic and composite spacecraft structures, including load path validation
• Experience owning or supporting structural verification efforts through analysis and test
• Proficiency with Python and/or MATLAB for analysis automation, data reduction, and reporting
• Experience using version control systems such as Git in an engineering analysis environment
• BS or MS in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline

Nice To Haves

• Strong ability to perform structural stress analysis and margin of safety calculations for primary and secondary spacecraft structures
• Deep understanding of load paths, structural behavior, and failure modes in metallic and composite structures
• Ability to build, interrogate, and validate finite element models using first-principles reasoning
• Proficiency in developing and applying hand calculations to verify and bound FEM results
• Ability to automate analysis post-processing and verification reporting using Python or MATLAB
• Clear technical communication skills for documenting assumptions, methods, and structural substantiation rationale

Responsibilities

• Own the structural finite element model (FEM) for primary and secondary spacecraft structures and maintain configuration control
• Perform stress, deflection, stability, and margin of safety analyses using FEM and first-principles hand calculations
• Substantiate metallic and composite structures, including strength, stiffness, and buckling assessments
• Develop and document structural verification approaches, assumptions, and acceptance rationale
• Support design trades and architecture decisions through analytical assessment of load paths and structural efficiency
• Partner directly with design engineers to validate and optimize primary and secondary structural designs for strength, stiffness, weight, cost, and manufacturability
• Develop Python-based tools to automate analysis workflows, post-processing, and margin reporting
• Collaborate with design, manufacturing, and test teams to resolve structural issues and assess nonconformances
• Support structural qualification and acceptance testing, including pre-test predictions and post-test correlation
• Contribute to structural documentation, analysis reports, and verification artifacts
