Blue Origin · Seattle, WA · Propulsion · first seen 2026-09-03

About the role

As part of a small team of engineers in the Blue Origin Engines business unit, you will perform thermal analysis to support the design and development of thruster systems. This role supports the full development cycle, from early design trades through hot-fire testing and hardware qualification, and gives you direct influence over how thruster hardware is designed and verified.

You should be comfortable working independently, contributing to design decisions, and communicating results clearly to the rest of the team.

Responsibilities

  • Perform detailed thermal analysis of thrusters and subassemblies, including design trade studies, component sizing, and design verification
  • Develop detailed thermal models using industry-standard tools to predict thruster and subsystem thermal behavior
  • Analyze thermal test data to anchor, validate, and refine thermal models and analyses
  • Support component design from a thermal perspective throughout the development cycle
  • Lead and support thermal design reviews and verification activities throughout the product lifecycle
  • Collaborate cross-functionally with propulsion, materials, manufacturing, and test teams to ensure designs meet thermal margins and safety requirements
  • Document analysis methods, assumptions, results, and recommendations
  • Contribute to the continuous improvement of thermal analysis processes, tools, and best practices within the team

Minimum Qualifications

  • 4+ years of professional experience related to thermal analysis
  • Strong technical fundamentals in fluids and thermodynamics
  • Experience with Thermal Desktop, SINDA FLUINT, and Ansys
  • Proficiency with 0-D and 1-D thermal and fluid analysis
  • Able to perform hand calculations to validate and improve models
  • Demonstrated ability to lead projects and work independently
  • 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

Preferred Qualifications

  • M.S. degree or higher in mechanical or aerospace engineering
  • 6+ years of thermal analysis of propulsion systems and components
