Senior Turbomachinery Thermal Engineer

Company Details

Millions of people living and working in space to benefit Earth.

We are a diverse team of collaborators, doers, and problem-solvers who are relentlessly committed to a culture of safety. This position will directly impact the history of space exploration and will require your dedication and detailed attention towards safe and repeatable space flight. Join us in lowering the cost of access to space and enabling Blue Origin’s vision of millions of people living and working in space to benefit Earth.

As a Senior Turbomachinery Thermal Engineer, you will work on the Engines Thermal Analysis team among other experts in heat transfer and flow network modeling. As part of this hard-working and accomplished group of engineers, you will directly contribute to the design and qualification of the most sophisticated liquid rocket engines being developed today. You will participate in all stages of rocket engine development, from conception through detailed design and test support.

As an expert in heat transfer with practical experience in industry standard tools, you’ll be responsible for quantifying the thermal state of turbomachinery components and assemblies. You will generate, maintain, and document 2d and 3d finite element analyses of whole turbopump assemblies and individual components. You will predict the thermal states of turbomachinery components and assemblies through acute transients to aide structural and clearance analyses that directly impact pump and seal performance. Relying on your solid fundamentals in heat transfer, you will anchor thermal models to test data and make recommendations for updated instrumentation suites on subsequent test campaigns.


  • Thermal design and analyses of rocket engine turbomachinery at varying levels of maturity and detail
    Meticulous bookkeeping of model status and changes through time
  • Define and anchor thermal predictions of turbomachinery components and assemblies to test data
  • Advocate for methods that will improve component and analysis performance and reliability


  • Bachelor’s degree in an engineering field is required
  • Minimum of 15 years of industry experience working directly with turbomachinery, with at least 10 years being in heat transfer or secondary flows design or analysis
  • Some portion of this experience must have been on turbomachinery for spaceflight applications
  • Experience with ANSYS Classic and Workbench for thermal analysis
  • Solid understanding of heat transfer, flow, and thermodynamic first principles
  • Good interpersonal skills and proficiency with efficiency tools
  • Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.


  • 15+ years of liquid rocket engine heat transfer and flow network experience
  • Experience with using Sinda/Fluint or Flownex flow network software to analyze turbomachinery systems
  • Prior job experience in thermal/fluid testing and instrumentation definition
  • Extensive knowledge surrounding cryogens and phase change heat transfer
