As a Structural Analyst on the Mechanical Engineering Team, you will be responsible for analysis of various structures across multiple projects including spacecraft, launch vehicle structures, and launch and test ground support equipment. You will use your knowledge of structural analysis to improve previous designs and influence new designs by minimizing weight and at the same time ensuring conformance to program and customer strength and stability requirements. You will leverage testing of hardware to correlate and validate analysis models.


  • Collaborate with design, manufacturing, and test engineering to develop hardware throughout the design lifecycle
  • Perform structural analyses by classical hand calculation and finite element analysis for composites and metals.
  • Perform linear and non-linear structural analysis, eigenvalue buckling analysis, non-linear buckling analysis, and modal finite element analysis using ANSYS and NX Nastran.
  • Develop test requirements to ensure adequate data for analysis correlation.
  • Validate finite element analysis with hand calculations and test data.
  • Review internal and external analyses.
  • Work with responsible and systems engineers to define required material properties and part modifications to meet structural requirements.
  • Write strength and stability margins to required program safety factors.



  • Master’s Degree in Mechanical, Aerospace, or civil engineering and 2+ years of relevant experience, or 5+ years with a Bachelor’s Degree.
  • Proficient with analytical simulation software and hand calculations for structural analysis.
  • Familiarity with aerospace standard analysis methods.
  • Ability to effectively work in a multi-discipline team and provide technical guidance and insight.
  • Exceptional comprehension of first principles related to structures and materials.
