Antares is building mass-producible, inherently safe, deployable microreactors for terrestrial, underwater, and space applications, with a mission to make clean energy abundant from Earth to the Asteroid Belt. The company has raised over $600M in venture capital and holds hundreds of millions in contracts with military services, NASA, and the Department of Energy. The team includes veterans from SpaceX, the White House, Pentagon, Department of Energy, MIT, and national laboratories.
As a Senior Turbomachinery Aerodynamics Engineer, you will own the aerodynamic and aeromechanical design of compressor and turbine stages for Antares nuclear reactors. You will drive turbomachinery development from early sizing and architecture trades through detailed aerodynamic design, structural and life analysis, and test validation. You will collaborate closely with rotordynamics, mechanical design, manufacturing, test, and systems engineers throughout the development lifecycle.
Key responsibilities include:
- Owning aerodynamic and structural design of compressor and turbine stages
- Supporting architecture trades through meanline analysis, preliminary sizing, and performance modeling
- Designing blades, vanes, diffusers, volutes, and related flow-path components
- Developing and maintaining compressor and turbine performance maps in coordination with system engineers responsible for Brayton-cycle performance
- Performing stress and life analysis of rotating hardware, including static structural, modal, LCF, HCF, and creep analysis
- Evaluating aerodynamic forcing and vane-blade interaction for structural and life assessments
- Developing and improving analysis and test methods to correlate predictions with component and rig testing
- Investigating performance and structural issues from development testing and implementing design improvements
- Contributing to turbomachinery design practices, analysis tools, and standards
- Supporting design reviews and technical decisions throughout the product lifecycle
The ideal candidate has strong experience designing compressors, turbines, pumps, or similar high-speed turbomachinery and can make sound engineering trade-offs between aerodynamic performance, structural integrity, life, manufacturability, and system requirements.
REQUIREMENTS:
Basic Qualifications:
- Bachelor's degree in Mechanical, Aerospace, or 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
Preferred Skills & Experience:
- Master's degree in Mechanical, Aerospace, or 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
Additional Requirements:
- Flexibility to support hardware development milestones, including occasional weekend or long-hour pushes
- ITAR compliance: 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
