Thermal Analyst II - Turbomachinery

Employer description

Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re 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!  

This role is part of the Blue Origin Engines business unit, where our focus is the design, development, manufacturing, and testing of engines and propulsion systems. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security, and human spaceflight.

As part of a hardworking team of engineers, you will analyze and help optimize turbomachinery and rotating hardware, including pumps, turbines, compressors, shafts, disks, bearings, and seal assemblies. Working alongside experts in heat transfer and flow network modeling, you will quantify the thermal state of rotating and static components and assemblies to support design, test, and operation. You will generate, maintain, and document analytical thermal models including FEA, CFD and fluid networks representing systems, components, assemblies and predict their thermal response through steady-state and transient operation to support structural, clearance, and life analyses that directly affect performance and safety. You will work closely with design and structural engineers to ensure integrated and consistent predictions. Relying on your fundamentals in heat transfer, you will contribute to test campaigns with instrumentation and test plan recommendations, with objectives to anchor thermal models and validate supporting system and hardware development.
