What you will do

• Derive and validate random vibration and shock environments using flight data, empirical methods, damage-based analysis, and relevant aerospace standards.
• Perform rotor-dynamics, flow-induced vibration, engine acoustics, and acoustic cavity coupling analyses.
• Process flight and engine test data using advanced signal-processing methods to resolve anomalies and guide design improvements.
• Develop frequency-based substructuring workflows and Craig-Bampton reduced-order models in Nastran for coupled-loads analysis.
• Provide technical direction for engine test-stand instrumentation and collaborate with propulsion, structures, and test organizations.
• Mentor dynamics engineers, lead technical risk-reduction activities, and present analyses to program leadership and external customers.

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related field.
• Experience in structural dynamics with expertise in high-frequency dynamic environments, random vibration, shock, rotor dynamics, flow-induced vibration, and engine acoustics.
