Reimagine What's Possible
Air Products is seeking a Turbomachinery Aerodynamic Design Manager to join our Rotoflow® business in Bethlehem, Pennsylvania. In this role you will serve as the Aerodynamics Domain Owner for Rotoflow®, providing technical leadership for aerodynamic design strategy, performance prediction methodologies, aerodynamic engineering tool improvements, and the continued advancement of aero capabilities across our global portfolio of turboexpanders, centrifugal compressors, and turbomachinery systems. You will also lead and develop a team of four Aero Engineers while supporting the successful execution of customer projects worldwide. This position follows a hybrid work arrangement with four days per week in the office and requires minimal travel, typically less than 10%.
Rotoflow®, an Air Products business, is a leading turbomachinery OEM serving customers around the world with new equipment, aftermarket services, and engineered solutions. For decades, Rotoflow has specialized in the design and manufacture of cryogenic and warm gas centrifugal turbomachinery supporting industrial gas, hydrocarbon, LNG, and petrochemical applications. Our products include compressor-loaded turboexpanders, generator-loaded power recovery expanders, and custom-engineered turbomachinery solutions designed to deliver exceptional performance, efficiency, and reliability.
This is not a traditional engineering management position. As the Aerodynamics Domain Owner, you will provide technical leadership for aerodynamic design, compressible flow applications, performance prediction methodologies, CFD-based analysis, and engineering best practices. You will guide the future direction of aerodynamic capabilities across the organization while remaining actively involved in the aerodynamic design and execution of customer projects. This is a unique opportunity to shape the future of aerodynamic design for one of the industry's most respected turbomachinery and turboexpander OEMs.
