Senior Turbomachinery Engineer

Senior Turbomachinery Engineer A growing engineering team is seeking a highly motivated Turbomachinery Engineer to take ownership of the power generation and/or primary cooling turbomachinery in advanced energy systems. This role involves the mechanical design and analysis of high-speed rotating machinery including compressors, turbines, and pumps for high-temperature applications. The ideal candidate will have a strong background in mechanical design, structural and thermal finite element analysis (FEA), rotordynamic simulations, and bearing selection and integration, along with hands-on experience building physical hardware. Responsibilities and Duties: Full ownership of machinery, from architecture down-selection to mass-production design. Develop detailed mechanical designs for turbomachinery components, including rotors, stators, housings, and seals. Perform static and dynamic structural analyses using FEA tools (ANSYS, Abaqus, or equivalent) to assess stresses, deformations, and fatigue life. Conduct thermal analysis to evaluate temperature distributions and thermal stresses under transient and steady-state conditions. Perform rotordynamic modeling and analysis to evaluate critical speeds, mode shapes, unbalance response, and stability. Select appropriate bearing types (e.g., rolling element, fluid film, magnetic) based on operating conditions and performance requirements. Evaluate bearing loads, life, and thermal performance. Prepare technical reports, design documentation, and presentation materials. Oversee the build and testing of prototype, first article, and production hardware. Required Qualifications and Skills: Bachelor's or Master's degree in Mechanical Engineering or a related field. 5+ years of experience in the design and analysis of turbomachinery, rotating equipment, or mechanisms. Proficiency in CAD and FEA tools (SolidWorks, ANSYS, Abaqus, etc.), including knowledge of GD&T. Excellent problem-solving, technical communication, and organizational skills. Desired Qualifications and Skills: Prior experience with supercritical CO? applications. Strong understanding of rotordynamic principles and tools (e.g., XLrotor, DyRoBeS, or equivalent). Knowledge of material selection for high-temperature, high-speed applications. Hands-on experience with turbomachinery testing and instrumentation. Experience translating broad machinery requirements (power, speed, bearing leakage) into a conceptual design, including wheel and shaft design, as well as bearing and alternator selection. Familiarity with AC power generation and power electronics. Familiarity with relevant industry standards (API, ASME, ISO). Basic programming knowledge (e.g. Python, C++, or equivalent). Prior nuclear experience is not required for this role.
