Original job 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 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

Culture Statement Don’t meet all desired requirements? Studies have shown that some people are less likely to apply to jobs unless they meet every single desired qualification. At Blue Origin, we are dedicated to building an authentic workplace, so if you’re excited about this role but your past experience doesn’t align perfectly with every desired qualification in the job description, we encourage you to apply anyway. You may be just the right candidate for this or other roles.

Export Control Regulations Applicants for employment at Blue Origin must be a U.S. citizen or national, U.S. permanent resident (i.e. current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
