About The Position

As a Structural Dynamics Engineer at Castelion, you will own the structural dynamics methodology used across our missile and aerospace systems. You will develop high-fidelity analytical models, validate them through testing, and provide the engineering insight that drives design decisions from concept through flight. You'll work across structures, propulsion, avionics, flight test, manufacturing, and test engineering to ensure our vehicles survive some of the harshest dynamic environments imaginable. This role is ideal for someone who enjoys combining analysis with real hardware testing and wants to influence vehicle architecture from day one.

Requirements

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related field (or equivalent experience)
3+ years of experience performing structural dynamics, loads, or vibration analysis
Experience with finite element modeling using FEMAP, NASTRAN, or equivalent FEA tools
Strong experience using MATLAB and/or Python for engineering analysis and data processing
Experience performing modal, vibration, shock, or transient dynamic analyses
Strong understanding of structural mechanics, dynamics, and aerospace loads environments
U.S. citizenship is required
Ability to obtain and maintain a U.S. government–issued security clearance
