Thermo-Mechanical Propulsion Engineer, Rotating Equipment

Blue Origin; Huntsville (AL); On-site; USD 121,000 - 169,000; Full time

Benefits offered by this job

Relocation provided

Travel up to 25% of time

Technical assessment in interviews

Job summary

Blue Origin Engines seeks a highly skilled engineer to own 2D axisymmetric thermo‑mechanical models of rotating equipment and to predict rotor/casing clearances across transients. You will integrate with secondary-flow, rotordynamics, and test groups to mature models through design lifecycle.

The role emphasizes campaigns from SRR to CDR, with strong collaboration across disciplines and a focus on reliability, life, and mission performance. Relocation and travel are involved.

Qualifications

• Bachelor's degree in Mechanical or Aerospace Engineering.
• At least 6 years of mechanical/structural/thermal analysis on high‑performance machinery.
• Hands-on transient thermal and nonlinear structural FEA in ANSYS.
• Experience building whole‑engine 2D axisymmetric thermo‑mechanical models.
• Ability to derive convective heat‑transfer boundary conditions from correlations.
• Experience in cross‑disciplinary engineering teams.
• Proven track record of ownership and delivering results.

Responsibilities

• Develop and own 2D axisymmetric thermo‑mechanical models of rotating equipment.
• Translate 3D geometry into 2D axisymmetric representations.
• Implement transient profiles and assess effects on clearances.
• Work with secondary-flow analysts to develop convection models.
• Apply thermal boundary conditions to structural models to predict gaps and margins.
• Perform structural margin and life assessment.
• Support system-level operability guidance and ConOps trades.
• Collaborate across disciplines to resolve hardware issues.
• Develop and maintain analysis-driven design requirements and documentation.
