Job Description

We are seeking a Rotordynamics Engineer to lead and support the analysis, design, validation, and troubleshooting of high-performance rotating machinery systems. This role spans the full product lifecycle—from early conceptual studies and trade analyses through detailed modeling, testing, field support, and root cause investigations. The ideal candidate has strong theoretical foundations in rotor dynamics, practical experience with real-world turbomachinery, and the ability to collaborate across aerodynamic, structural, mechanical, manufacturing, testing, and software development teams. Level and scope of responsibility will be adjusted based on experience.

Job Responsibility

  • Conduct comprehensive rotordynamics analyses
  • Develop analytical and numerical models of rotor-bearing-seal systems
  • Analyze system sensitivity to bearing stiffness, damping, support flexibility, and operating conditions
  • Provide input on design of shafts, and support structures
  • Interface with clients to discuss analysis goals, required information, and project timeline
  • Assist in selecting appropriate bearing technology
  • Demonstrate understanding of common turbomachinery bearing technologies
  • Assess seal dynamics and rotordynamic cross-coupling effects
  • Optimize bearing performance and system stability
  • Work with test engineers to define instrumentation and test plans
  • Diagnose vibration, instability, and resonance issues
  • Conduct root cause analysis of machinery failures
  • Provide technical support during commissioning, troubleshooting, and maintenance
  • Contribute to internal methods development
  • Support commercial software development
  • Prepare detailed technical reports, documentation, and presentations
  • Communicate technical findings to internal teams and external customers
  • Contribute to proposal efforts and technical reviews

Requirements

  • B.S. or M.S. in Mechanical Engineering or closely related field
  • Strong fundamentals in rotordynamics, vibrations, and dynamics of rotating systems
  • Experience with rotordynamic analysis tools (e.g., DyRoBeS, XLTRC2, ARMD, or equivalent)
  • Experience correlating analytical models with experimental data
  • Be familiar with relevant industry standards (API, aerospace, energy sector requirements)
  • Strong problem-solving ability and engineering judgment
  • Excellent written and verbal communication skills

Nice to have

  • Experience with high-speed turbomachinery (compressors, turbines, pumps, expanders)
  • Exposure to experimental testing, instrumentation, and data acquisition
  • Programming/scripting experience (MATLAB, Python, or similar)
  • Experience contributing to analysis method or software development
