Propulsion Engineer II, Thermal Systems

Application close date:

At Blue Origin we envision millions of people living and working in space for the benefit of Earth. Were working to develop reusable safe and low-cost space vehicles and systems within a culture of safety collaboration and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

As part of a hardworking team of engineers you will design analyze and optimize the next generation of heat exchangers for demanding thermalfluid environments. You will work with crossfunctional teams to develop innovative higheffectiveness lowpressuredrop thermal solutions and to mature them from concept through qualification. You will be responsible for defining heat exchanger cores headers manifolds and assemblies to support fabrication testing and production. A successful candidate will apply their knowledge across multiple applications involving heat transfer between fluids and phases demonstrating versatility and technical depth as designs advance through successive iterations.
