Thermal Analyst II - Turbomachinery

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.

Special Mentions

• Relocation provided
• Travel expected up to 10% of the time

Responsibilities include but are not limited to:

• Perform thermal design and analysis of rotating and static turbomachinery components and assemblies (rotors, disks, shafts, housings, bearings, and seals) from concept through fabrication, testing, and into service
• Develop, maintain, and document analytical thermal models, including FEA, CFD and fluid networks, of individual turbomachinery components and full assemblies, supported by hand calculations
• Predict steady-state and transient thermal states of turbomachinery hardware across the operating envelope to support structural, clearance, and life assessments
• Support cooling and lubrication system design, including sizing of cooling and lubrication flows and evaluating component heat generation and heat rejection
• Anchor thermal predictions to component and system test data, identify discrepancies, and recommend model updates, and support test plan and instrumentation definition to verify thermal requirements
• Collaborate with team members from various fields and backgrounds on trade studies that consider operating environment and duty cycle to optimize design performance and durability
• Contribute to process automation tools for model creation, thermal balance checks, and analysis report generation, and participate in peer reviews of thermal analyses

Minimum Qualifications

• Experience in rotating machinery design and analysis (pumps, turbines, compressors, fans)
• Experience with flow network modeling software (Flownex, Sinda/Fluint) to analyze secondary flow systems such as disk cavities, seals, or blade and vane cooling passages
• Experience with conjugate heat transfer (CHT) or applying CFD-derived boundary conditions in thermal models
• Familiarity with sizing cooling and lubrication systems for hardware requiring continuous heat rejection
• Working knowledge of high-temperature material properties and selection
• Prior job experience in thermal/fluid testing and instrumentation definition
• Demonstrated knowledge of cryogenic fluids and phase change heat transfer
• Experience with Agentic AI
