Job summary

Castelion seeks a Structural Dynamics Engineer to own the dynamics methodology across missile and aerospace systems. You will develop high-fidelity analytical models, validate them through testing, and drive design decisions from concept through flight.

You’ll collaborate across structures, propulsion, avionics, flight test and manufacturing to ensure vehicle performance in harsh environments, translating analysis into hardware testing and iterative validation.

Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or related field.
• 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 and data processing.
• Experience performing modal, vibration, shock, or transient dynamic analyses.
• 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.
