Sr. Heat Transfer Engineer - Turbomachinery

Responsibilities

• Own thermal and heat transfer analysis for rotating and stationary turbomachinery components.
• Develop and maintain secondary air system models, including cooling and sealing flow circuits.
• Generate thermal boundary conditions for structural and clearance analysis.
• Collaborate with aero, mechanical design, and systems teams to ensure robust thermal integration and operability.
• Work with test and validation teams to define thermal instrumentation requirements and interpret test data.
• Support transient thermal analysis for startup, shutdown, and off-nominal operating conditions.
• Document results and methods in formal design memos and interface reports.
• Contribute to the development of analysis tools and modeling standards for thermal integration.

Requirements

• 5+ years of experience in heat transfer and secondary flow analysis for turbomachinery (gas turbine, aero engine, sCO₂, etc.).
• Experience with thermal FEA, internal cooling design, and/or system-level secondary air system modeling.
• Proficiency in tools such as ANSYS, CFX, Siemens Flowmaster, or equivalent.
• Understanding of transient thermal behavior and its effect on clearances and mechanical integrity.
• Familiarity with turbomachinery design principles and thermomechanical integration.
• Ability to manage thermal interfaces across teams and contribute to system-level decisions.
• Strong communication and documentation skills.
