Senior Turbomachinery Aerodynamics Engineer

The role

You will own the aerodynamic and aeromechanical design of compressor and turbine stages for Antares nuclear reactors. You will develop turbomachinery from early sizing and architecture trades through detailed design, analysis, and test validation.

What you will do

• Own the aerodynamic and structural design of compressor and turbine stages.
• Support architecture trades through meanline analysis, preliminary sizing, and performance modeling.
• Design blades, vanes, diffusers, volutes, and related flow-path components.
• Develop and maintain compressor and turbine performance maps.
• Perform stress and life analysis of rotating hardware.
• Evaluate aerodynamic forcing and vane-blade interaction for structural and life assessments.
• Develop and improve analysis and test methods to correlate predictions with testing.
• Investigate performance and structural issues identified during development testing.
• Contribute to turbomachinery design practices, analysis tools, and standards.
• Support design reviews and technical decisions throughout the product lifecycle.

Required qualifications

• Bachelor’s degree in Mechanical, Aerospace, or a related engineering discipline.
• 5+ years of professional experience designing compressors, pumps, and/or turbines.
• Strong understanding of turbomachinery aerodynamics and aerodynamic design methods.
• Experience with structural analysis of turbomachinery rotating components.
• Knowledge of life-limiting mechanisms in high-speed rotating hardware including fatigue, creep, and modal resonance.
• Experience making engineering tradeoffs involving performance, structural margin, life, manufacturability, cost, and schedule.
• Demonstrated ability to communicate technical information clearly.
• Flexibility to support hardware development milestones, including occasional weekend or long-hour pushes.

Nice to have

• Master’s degree in Mechanical, Aerospace, or a related engineering discipline.
• 7+ years of professional experience designing high-performance turbomachinery.
• Proficiency with ANSYS Mechanical, CFX, BladeGen, TurboGrid.
• Experience with meanline and preliminary design tools such as AxSTREAM, PUMPAL, or internally developed sizing and analysis tools.
• Experience conducting forced-response analysis of vane-blade interactions.
• Experience validating hardware through test and correlating analytical models with test data.
• Proficiency with NX for 3D CAD design and drafting.
• Strong organizational and communication skills.

Before you apply

• Applicant must be a U.S. citizen or national, U.S. lawful, permanent resident, Refugee, or Asylee, or be eligible to obtain required authorizations from the U.S. Department of State.
