We are seeking an expert Senior Rotordynamics Engineer to lead advanced analysis, diagnostics, and design support for high-speed rotating machinery systems such as gas/steam turbines, compressors, and expanders. The successful candidate will be responsible for solving complex vibration and instability problems, conducting high-fidelity rotor modeling, and mentoring junior engineers. This role is critical in ensuring the reliability, performance, and mechanical integrity of rotating equipment assets.
The ideal candidate will bring deep technical knowledge, leadership in analytical and testing methodologies, and hands-on experience in both OEM and operational environments.
Perform and lead comprehensive rotor-bearing-seal system modeling including lateral, torsional, and axial dynamic behavior.
Analyze and predict critical speeds, stability margins, unbalance responses, natural frequencies, and damping using tools such as DyRoBeS, XLROTOR, MADYN 2000, or ANSYS.
Evaluate system sensitivity to component changes (e.g., bearing stiffness, seal clearances, rotor mass distribution).
Lead field investigations of machinery vibration issues, start-up instabilities, and resonant behavior.
Analyze real-time vibration data (orbits, waterfall plots, Bode/Phase plots) to identify faults and provide resolution strategies.
Conduct or support field balancing, commissioning, and trip analysis of critical rotating equipment.
Serve as a rotordynamic authority for the design of shafts, bearings, seals, dampers, and couplings.
Review and validate designs for new machinery, retrofits, or upgrades—ensuring they meet performance and stability requirements.
Provide recommendations for vibration mitigation, support structure design, and material selection.
Define and lead rotordynamic test campaigns: full-speed full-load tests, modal testing, and performance validation.
Interface with test labs and OEMs to ensure rotor behavior aligns with predictive models.
Mentor and review work by junior/mid-level engineers; guide best practices in rotordynamic modeling and troubleshooting.
Collaborate with cross-disciplinary teams: mechanical design, controls, reliability, operations, and OEM engineers.
Serve as SME in RCA teams addressing recurring vibration-related failures or rotating equipment issues.
Prepare detailed technical reports and present results to management, clients, or cross-functional teams.
Contribute to internal design standards, knowledge bases, and technology roadmaps related to rotordynamics and vibration control.
Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or equivalent required.
Master’s or PhD in Rotordynamics, Machine Design, or Structural/Vibration Engineering preferred.
7+ years of progressive experience in rotordynamics, vibration analysis, and rotating equipment engineering.
Hands-on experience with high-speed equipment such as gas/steam turbines, centrifugal compressors, expanders, and electric motors.
Expert in analytical tools: DyRoBeS, MADYN, ANSYS, XLROTOR, MATLAB, Python.
Deep understanding of rotor-bearing dynamics, critical speed mapping, instability mechanisms, and damping solutions.
Proficiency with vibration monitoring tools and systems: Bently Nevada, SKF, ADRE, or Brüel & Kjær.
Strong technical judgment and problem-solving skills
Excellent communication and reporting skills, including to non-technical stakeholders
Leadership in cross-functional teams and mentoring roles
High attention to detail with a proactive, ownership mindset
