About Us
At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.
The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy.
About the Role
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 develop turbomachinery from early sizing and architecture trades through detailed aerodynamic design, structural and life analysis, and test validation. You will work closely with rotordynamics, mechanical design, manufacturing, test, and systems engineers throughout development.
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.
Roles & Responsibilities:
-
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 and work closely with system engineers responsible for Brayton-cycle performance.
-
Perform stress and life analysis of rotating hardware, including static structural, modal, LCF, HCF, and creep analysis.
-
Evaluate aerodynamic forcing and vane-blade interaction for structural and life assessments.
-
Develop and improve analysis and test methods to correlate aerodynamic, structural, and life predictions with component and rig testing.
-
Investigate performance and structural issues identified during development testing and implement design improvements.
