  • Secondary Air Systems & Clearance Design
  • Use in-house and commercial simulation tools to:
  • Develop models that describe the cooling air supply to hot gas-path components in gas turbines and evaluate the results.
  • Simulate transient heating and expansion of the entire turbine to determine optimal assembly gaps between rotating and stationary components.
  • Analyze model results and derive design-relevant conclusions.
  • Contributing to the conceptual design for gas turbines and evaluate operational data and findings from prototypes and the current fleet to support design improvements and reliability.


What You Bring

  • A Bachelor's degree in Mechanical Engineering or a related engineering field is required; a Master's degree or Ph.D in Mechanical Engineering or a related engineering field is a plus.
  • 0-2 or more years of relevant experience in gas turbines or cooling air systems is desirable; Candidates with more direct experience may be eligible for a more senior level position.
