• Utilize first principle approaches with a good general knowledge of metallics and composite structures.
• Develop GFEM (Global Finite Element Models) and DFEM (Detail Finite Element Models).
• Write Margins of Safety (MoS) for various candidate materials and make recommendations to designers to improve geometries.
• Create and maintain material properties database for use in commercial FEA code simulations.
• Plan and execute ground static and dynamic test of complex mechanisms and structures.
• Build axisymmetric FEM models of complex aerospace structural assemblies.
• Develop internal processes for performing structural analysis and be willing to instruct design engineers in simplified stress analysis.

Basic Qualifications

• 3-5 years of direct experience.
• Experience with thermal/pressure load coupling.
• Proficiency in a commercial structural analysis code (FEMAP, ANSYS, HyperMesh, Abaqus).
• Understanding of basic coding (Python, MATLAB).
• Entry-level experience with a commercial CAD code (SolidWorks, NX, Autodesk).

All employees are granted long-term stock incentives as part of their employment as Castelion. All employees receive access to comprehensive medial, vision, and dental insurance, and the company offers three weeks of paid time off per year.
