Job summary

Blue Origin seeks a Propulsion Engineer to own 2D axisymmetric thermo-mechanical models of rotating equipment, predict temperatures, clearances, and margins across transients. You will collaborate with design, aero/CFD, secondary flow, and test teams to mature models through the design lifecycle and support mission objectives.

The role requires a Bachelor's in Mechanical or Aerospace engineering and 6+ years of ANSYS experience with transient thermal and nonlinear structural analysis; relocation

Qualifications

• ,
• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field
• ,
• Minimum of 6 years of experience in mechanical / structural / thermal analysis of machinery systems or comparable high-performance hardware
• ,
• Hands-on experience with transient thermal and nonlinear structural finite element analysis in ANSYS
• ,
• Experience creating whole-engine/2D axisymmetric thermo-mechanical models of rotating equipment
• ,
• Ability to derive convective heat-transfer boundary conditions from correlations
• ,
• Cross-disciplinary collaboration experience
• ,
• Track record of ownership and delivering results

Responsibilities

• Develop, maintain, and own 2D axisymmetric thermo-mechanical models of rotating equipment
• Translate 3D geometry into efficient 2D axisymmetric representations
• Implement transient operating profiles and assess effects on clearances
• Collaborate with secondary-flow analysts to develop conjugate models
• Apply boundary conditions to predict rotor and casing margins across transients
• Perform structural margin, bolted-joint, and interference-fit assessments
• Synthesize results into operability guidance for system-level tradeoffs
