Structural Dynamics Engineer — Flight Systems & Testing

Castelion; Torrance (CA); On-site; USD 110,000 - 140,000; Full time

Job summary

Castelion seeks a Structural Dynamics Engineer to own the dynamics methodology for missile and aerospace systems, developing high-fidelity analytical models and validating them through testing. You will influence design decisions from concept through flight, collaborating across structures, propulsion, avionics, flight test, and manufacturing.

This role requires a strong background in structural dynamics, FEMAP/NASTRAN, and MATLAB/Python, with a track record of correlating models to test data

Qualifications

• Bachelor's degree in Mechanical, Aerospace, or Structural Engineering (or equivalent).
• 3+ years of structural dynamics, loads, or vibration analysis.
• Experience with FEMAP, NASTRAN, or equivalent FEA tools.
• Strong MATLAB and/or Python for engineering analysis.
• Experience performing modal, vibration, shock, or transient dynamic analyses.
• Strong understanding of structural mechanics, dynamics, and aerospace loads environments.

Responsibilities

• Develop and continually improve Castelion's structural dynamics and loads analysis methodologies.
• Perform modal, random vibration, shock, transient, and frequency response analyses for flight hardware.
• Generate structural dynamics models and simulation results that directly influence critical engineering decisions.
• Define dynamic test strategies spanning component, subsystem, and full vehicle qualification.
• Correlate analytical models with test data and continually improve model fidelity.
• Partner closely with design, manufacturing, propulsion, avionics, and flight test teams to optimize hardware performance.
• Develop automated analysis tools and workflows to improve engineering efficiency.
• Support qualification, acceptance, environmental, and flight testing activities.
• Drive technical decisions in a fast-paced, highly collaborative development environment.
