This role requires the ability to analyze vibration, stability, critical speeds, and dynamic behavior of rotating systems while providing technical leadership across complex aerospace engineering programs.

Key Responsibilities

• Perform advanced rotor dynamics and shafting structural analyses for aerospace rotating systems.
• Analyze vibration, stability, and dynamic behavior of fans, compressors, turbines, shafts, and related rotating components.
• Predict critical speeds and evaluate rotating system performance across operating speed ranges.
• Develop and interpret whirl speed maps and Campbell diagrams.
• Analyze displacement, forces, and moments resulting from rotor imbalance.
• Perform finite element analysis using ANSYS APDL and/or ANSYS Workbench.
• Apply 1D beam-based FEA techniques to rotor and shafting analyses.
• Support complex mechanical component and system design activities.
• Evaluate engineering risks and recommend appropriate design solutions.
• Lead technical and mechanical design reviews.
• Conduct engineering risk assessments and support resolution of complex technical issues.
• Collaborate with multidisciplinary engineering teams throughout design and development activities.
• Provide technical leadership and mentorship to engineering team members.
• Support mechanical design projects throughout the aerospace product development lifecycle.

Qualifications
