Sr. Rotordynamics Engineer

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 dynamic and dedicated team of engineers, you will lead the rotordynamic assessments for our rotating machinery on assigned program. You will apply your technical expertise in structural dynamics, vibration, fluid-film and rolling-element bearings, seals, and thermal-structural behavior to ensure rotating hardware is stable, balanced, and robust across its full operating range. We are looking for someone who can demonstrate technical excellence, leadership skills, and commitment to quality while advancing our mission.

Responsibilities:

• Own rotordynamic analysis for rotating machinery, from initial requirements through design, qualification, and operation
• Collaborate with design, structural, thermal, and test engineers to resolve rotor-related design trades and nonconformance dispositions
• Perform lateral, torsional, and axial rotordynamic analyses, including critical speed maps, damped natural frequencies, stability, unbalance response, and transient run-up and coast-down response
• Model rotor support elements, including rolling-element and fluid-film bearings, annular and labyrinth seals, dampers, and couplings, and their interaction with the casing and supporting structure
• Define rotordynamic requirements and design margins for design teams, including balance, bearing stiffness and damping, seal clearances, and operating speed separation margins
• Develop test requirements and support test operations including instrumentation plans, procedures for spin, balance, and rig or engine rotordynamic testing.
• Correlate test data to analytical models and update models and design guidance based on results.
• Investigate rotor-related anomalies such as subsynchronous whirl, rubs, instability, and bearing distress, and drive root cause and corrective action
• Develop and maintain rotordynamic analysis methods, tools, and standards, while automating recurring analyses
• Document analyses and present findings and risk assessments at design reviews

Minimum Qualifications:

• Bachelor's degree in Mechanical, Aerospace Engineering, or related technical field
• Minimum of 10 years of industry experience in relevant engineering discipline
• Demonstrated experience in rotordynamics, structural dynamics, or vibration analysis of rotating machinery
• Working knowledge of rotordynamic theory, including critical speeds, mode shapes, damping, stability, and unbalance response
• Experience with rotordynamic or finite element analysis software (for example XLTRC2, DyRoBeS, MADYN, ANSYS, or equivalent)
• Experience with scripting or programming for analysis and post-processing (for example Python or MATLAB)
• Experience with data analysis and data processing

Preferred Qualifications:

• Master's degree or higher in engineering discipline with a rotordynamics, vibrations, or structural dynamics focus
• Experience with high-speed turbomachinery such as rocket engine turbopumps, gas turbines, or high-speed machinery
• Experience modeling fluid-film, hydrostatic, or process-fluid-lubricated bearings and seals and their effect on rotor stability
• Experience with coupled rotor-casing-structure finite element models
• Experience planning and interpreting rotordynamic test data from component, rig, or engine tests, including balancing and instrumentation
• Experience with subsynchronous vibration, fluid-induced instability, and rub dynamics
• Experience with torsional dynamics of drivetrain systems
• Experience with hardware development and testing, including design reviews and qualification programs
• Experience developing analysis tools or automating analysis workflows
