Sr. Mechanical Engineer - Turbomachinery

The role

This person will lead the design and analysis of rotors and casings for turbomachinery in a supercritical CO2-based power cycle. The role involves conceptual design, assembly architecture selection, material selection, and structural analysis.

What you will do

• Design and optimize rotors and/or casings for high-performance turbomachinery using NX.
• Select assembly architectures and materials to meet performance and reliability requirements.
• Size and analyze bolted joints, seals, and piping flanges for structural integrity.
• Perform static and transient thermomechanical analysis using ANSYS.
• Conduct modal analysis of both stationary and rotating systems to evaluate dynamic behavior.
• Perform thermal analysis to assess the effects of temperature gradients and thermal expansion.
• Ensure designs meet operational, thermal, and mechanical performance requirements.
• Collaborate with combustion and systems teams.
• Support manufacturing, assembly, and testing efforts to validate designs.

Required qualifications

• Bachelor’s degree in Mechanical, Aerospace, or a related Engineering field.
• 3+ years of experience in turbomachinery design or mechanical system engineering.
• Proficiency in ANSYS FEM software for stress, thermal, and thermomechanical analysis.
• Strong understanding of bolted joint, seal, and flange design.
• Experience with static, transient, and thermal structural analysis of rotating systems.
• Familiarity with materials selection for high-stress and high-temperature applications.

Nice to have

• Experience in creep analysis for high-temperature applications.
• Knowledge of rotordynamics and vibration analysis of rotating machinery.
• Familiarity with bearing design, damping, and balancing of rotating components.
• Experience working with supercritical CO2 or high-density working fluids.
• Proficiency in NX CAD software
• Experience in startup or R&D environments.
