About the role

Key responsibilities & impact

Develop, maintain, and own 2D axisymmetric thermo-mechanical whole-engine/whole-pump models of rotating equipment.
Translate 3D component and assembly geometry into efficient 2D axisymmetric representations.
Implement transient operating profiles and assess their effect on differential growth and clearances.
Work closely with secondary-flow analysts to develop conjugate thermal-fluid models.
Apply thermal boundary conditions to axisymmetric structural models to predict rotor stack separation margin.
Perform component structural margin assessments using 2D and 3D ANSYS.
Synthesize thermal and structural analysis results into actionable operability guidance.
Collaborate across disciplines—design, aero/CFD, secondary flow, rotordynamics, materials, and test.

Requirements

What you’ll need

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
Minimum of 8 years of experience in mechanical/structural/thermal analysis of rotating machinery or comparable high-performance hardware.
Hands-on experience with transient thermal and nonlinear structural finite element analysis in ANSYS.
Demonstrated experience building whole-engine/2D axisymmetric thermo-mechanical models of rotating equipment.
Ability to independently derive convective heat-transfer boundary conditions from engineering correlations.
Experience working in cross-disciplinary engineering teams.
A track record of taking ownership, showing resilience in the face of challenges, and consistently delivering results.
