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 Team
The Antares Reactor Deployments team is responsible for bringing the Antares R1 microreactor from the factory to operational service. Working across engineering, manufacturing, licensing, construction, supply chain, and operations, the team develops repeatable deployment solutions that enable rapid installation of factory-built microreactors at commercial, defense, and government sites.
As a Civil and Structural Engineer, you will lead the development of deployment sites that support safe, efficient, and cost-effective reactor installation. You'll evaluate prospective sites, develop standardized civil infrastructure, and work with multidisciplinary engineering teams to create modular site designs that can be deployed repeatedly with minimal site-specific customization. This role spans the full project lifecycle—from customer site evaluation and conceptual planning through detailed design, permitting, construction, commissioning, and fleet deployment. You'll help establish the civil engineering standards and deployment methodologies that enable Antares to scale reactor deployments while maintaining the highest standards of safety, quality, and constructibility. Success in this role requires close collaboration with reactor, structural, mechanical, electrical, licensing, manufacturing, construction, and operations teams to ensure each deployment site is optimized for rapid installation, long-term operation, and regulatory compliance.
Roles and Responsibilities:
-
Lead civil engineering activities supporting deployment of the Antares R1 microreactor.
-
Evaluate prospective deployment sites for geotechnical conditions, grading, drainage, utilities, transportation access, constructibility, environmental constraints, and permitting requirements.
