Full Job Description
A Snapshot of Your Day
As the Lead Thermal Fluids Engineer, you will provide technical leadership for the design, analysis, and optimization of gas turbine cooling systems, secondary air systems (SAS), sealing technologies, and clearance management strategies. Working with a global engineering team, you will help define the thermal-fluid architecture of next-generation gas turbines while supporting operational fleet performance, reliability, durability, and efficiency improvements.
You will serve as the organization's subject matter expert for thermal-fluid simulation, aerothermal analysis, and whole-engine thermal behavior, influencing critical design decisions from concept development through field operation. Your expertise will directly impact turbine performance, emissions, availability, and lifecycle cost for some of the world's most advanced power-generation technologies.
