Senior, Thermo-Mechanical Design Engineer - Reactor Cavity Cooling Systems
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.
Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Los Alamos, Idaho, and Oak Ridge. Antares has raised over $130M in venture capital from top-tier investors and has over $13M in government funding.
About the Team
As a Senior, Thermo-Mechanical Design Engineer, you will be the Responsible Engineer (RE) for the Reactor Cavity Cooling System (RCCS), leading the design and analysis of a critical deployment system. You will be responsible for the thermal, mechanical, and piping design of the RCCS, ensuring the reactor cavity and surrounding structures remain within design temperature limits, while minimizing wasted thermal power. This role involves thermal-fluid analysis, piping and structural sizing, filtration system design, and integration of piping, supports, stacks, and cavity components. The ideal candidate has expertise in thermal-fluid systems, HVAC, piping, and structural design, and enjoys solving multidisciplinary engineering challenges in a highly constrained design environment.
Roles and Responsibilities:
- Perform thermal-fluid, mechanical, and structural analyses to support the sizing, layout, and optimization of cooling system components, including piping, ducts, stacks, supports, filtration equipment, and reactor cavity structures.
- Define system architecture, operating limits, design margins, and control strategies to ensure reliable performance across a...
