About The Position

To build our space systems, we need rockstars of all experience levels who can directly work the full product lifecycle of several challenging assemblies, including pressurized structures, launch adapters, mechanisms, tooling, and more.

Requirements

3+ years of industry experience in mechanical or aerospace engineering
Bachelor’s degree in an applicable field
Experience with analyzing / dispositioning non-conformances
Experience with hand calculations including free-body diagrams for internal and reaction load derivation
Demonstrated knowledge of bolted joint calculations (bolt preload, joint stiffness, shear-tension interaction, insert pull-out, etc.)
Strong experience with classical and aerospace analysis methods (Bruhn, Niu, Roark, Blodgett, Shigley, etc.)
Understanding of FEM modeling techniques (boundary conditions, bolted connections, contact, verification methods, etc.)
Mesh generation (ex: mid-surfacing) and understanding of element types
Analysis of stability critical structures (local buckling phenomenon, global buckling, crippling)
Experience with development and/or qualification testing (test requirements, setup/configuration, test predictions, test conduct/monitoring, etc.)
Demonstrated knowledge of vehicle load path and stress analysis of metallic and/or composite structures (pressure vessels, skin-stringer, fittings, sandwich panels, etc.)
Demonstrated expertise with at least two of the following pre-post/solver codes: SimCenter, FEMAP, Ansys, Nastran, Optistruct, LS Dyna, Hypermesh, Hypersizer, NASGRO, Abaqus, IMAT
