Turbomachinery Design Engineer

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.

As a Responsible Engineer for Turbo machinery, you will be a key member of the Reactor Hardware Team. You will own turbo machinery hardware for Antares nuclear reactors from concept through development, qualification, and production. You will own the technical execution of the complete turbo machine, coordinating analysis, design, manufacturing, test, and supplier activities to deliver hardware that meets program requirements and schedule.

The ideal candidate has experience taking complex mechanical designs from concept to production. You should be comfortable making engineering decisions with incomplete information, balancing performance, reliability, manufacturability, cost, risk, and schedule. You should be able to identify the work required to retire technical risk, delegate effectively to subject matter experts, and maintain ownership of the overall result.

• Own new and existing turbo machinery hardware through development and production.

• Lead the design, analysis, build, and test of turbo machinery for Antares nuclear reactors.

• Translate system requirements into turbo machinery requirements, interfaces, and verification plans.

• Coordinate work across aerodynamics, mechanical design, structures, rotor dynamics, bearings, thermal analysis, manufacturing, and test.

• Define development and test plans that retire the highest technical risks early.

• Work closely with external suppliers and Antares manufacturing, test, and quality engineers to deliver hardware on schedule.

• Investigate issues during manufacturing and test, identify root causes, and drive corrective actions to closure.

• Improve existing designs to increase reliability and manufacturability, reduce cost and lead time.

• Lead design reviews and communicate technical status, risks, and decisions to engineering and program leadership.

• Bachelor’s degree in Mechanical, Aerospace, or a related engineering discipline.

• 7+ years of full-cycle design engineering experience.

• Experience releasing production-intent mechanical drawings and models for fabrication, including GD&T and tolerance stack-up.

• Working knowledge of turbo machinery and high-speed rotating machinery.

• Experience making engineering tradeoffs involving performance, manufacturability, cost, risk, and schedule.

• Demonstrated ability to break down complex engineering problems, prioritize work, and drive technical issues to closure.

• Ability to coordinate and delegate technical work while maintaining ownership of the complete hardware.

• Master’s degree in Mechanical, Aerospace, or a related engineering discipline.

• 8+ years of experience in design and ownership of turbo machinery.

• Experience serving as a responsible engineer, design owner, technical lead, or equivalent role for complex hardware.

• Experience working directly with suppliers and…
