Propulsion Engineer - Turbomachinery II

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, analysts, and technicians, we are looking for the next teammate to own hardware lifecycle design and production introduction for the next generation of turbomachinery to help advance Blue Origin's vision of millions of people living and working in space to benefit Earth. In this Propulsion Engineer role, you will serve as the owner of hardware and subassemblies through the design, performance metrics, analysis, manufacture, and production deliveries. You will work closely with the Branch Technical Lead and design leads ensuring that turbomachinery design decisions are informed by and meet system-level performance and operability requirements.

We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!

Special Mentions

• Relocation provided
• Travel up to 25% of the time

Responsibilities include but are not limited to:

• Design and analyze designs across the core turbomachinery disciplines: hydrodynamics, static hardware, sealing strategies, and thermal management.
• Analyze to and help establish the margins required for safe designs
• Drive continuous improvement of analysis tools, methods, and automation.
• Mentor engineers in turbomachinery fundamentals, engineering judgment, and the rationale behind design standards.
• Support hardware build, assembly, acceptance testing, and anomaly investigation; provide engineering dispositions for non-conforming turbomachinery hardware.
• Develop and maintain design requirements and documentation; contribute technical artifacts to subsystem and program gated reviews (SRR, PDR, CDR, MRR, TRR).

Minimum Qualifications

• B.S. in Mechanical Engineering or Aerospace Engineering, with emphasis on turbomachinery, fluid mechanics, or thermodynamics.
• 2+ years of experience in turbomachinery design and analysis for aerospace propulsion systems (turbopumps, gas turbines, or power turbines).
• Ability to perform or evaluate analysis in: meanline aerodynamic design, CFD, secondary flow and seal modeling, structural analysis (static and fatigue), dynamic loading and forced response (Campbell diagrams, modal analysis), and rotordynamics.
• Understanding of margins required for safe turbomachinery designs in each of these disciplines.
• Basic knowledge of how turbomachinery performance characteristics propagate into system-level behavior and vice versa.
• Proficiency with commercial analysis tools (ANSYS suite or equivalent) and scripting for analysis automation (Python preferred).
• Familiarity with industry standards, including but not limited to relevant AIAA/AGMA design practices.
• Experience working in cross-disciplinary engineering teams.

Preferred Qualifications

• M.S. in Mechanical Engineering or Aerospace Engineering, with emphasis on turbomachinery, fluid mechanics, or thermodynamics.
• 5+ years of relevant industry experience.
• Experience with rocket propulsion turbomachinery (LOX/LH2, LOX/RP-1, LOX/CH4, or similar).
• Experience with closed-loop cycle turbomachinery designs and systems.
• Familiarity with additive manufacturing for turbomachinery components (blisks, impellers, housings).
• Experience with non-traditional rotor support systems (hydrostatic bearings, foil bearings).
• Experience with transient operability analysis — spool-up, load rejection, and thermal transients and their effects on turbomachinery reliability and life.
• Familiarity with NASA GFSSP, Sinda/FLUINT, or equivalent flow network solvers.
• Experience with parametric cost modeling and design-to-cost trades.
• Prior experience at a rocket propulsion or gas turbine OEM.
• A track record of taking ownership, showing resilience in the face of challenges, and consistently delivering results.
• Demonstrated use of — or genuine enthusiasm to adopt — modern AI-assisted engineering tools (e.g., LLM-based design / analysis / scripting assistants integrated into the daily development environment).
