Job summary

Blue Origin, based in Seattle, WA, seeks a Propulsion Engineer to own thermo-mechanical modeling of large-scale rotating hardware. You will build 2D axisymmetric whole-engine models, couple with flow networks, and predict temperatures, clearances, and margins across transients.

You will work with integration and test teams for model validation. The role requires hands-on ANSYS, scripting in Python/MATLAB, and experience with rotating equipment.

Qualifications

• Bachelor's degree in Mechanical or Aerospace Engineering.
• 6+ years of mechanical/structural/thermal analysis experience.
• Hands-on ANSYS transient thermal and nonlinear analysis.
• Experience building whole-engine 2D axisymmetric thermo-mechanical models.
• Ability to derive convective heat-transfer boundary conditions from correlations.
• Cross-disciplinary teamwork background.
• Proven ownership and results delivery.

Responsibilities

• Develop and own 2D axisymmetric thermo-mechanical models of rotating equipment.
• Translate 3D geometry into efficient 2D axisymmetric representations.
• Implement transient thermal profiles and assess effects on clearances.
• Collaborate with secondary-flow analysts for integrated models.
• Apply boundary conditions to predict rotor casing behavior across transients.
• Perform margin and life assessments using ANSYS.
• Document results and support program reviews.
