Hadron Energy
Lead Mechanical Engineer @ Hadron Energy
Overview
Overview
Hadron Energy specializes in Micro Modular Reactor (MMR) development, design, and research based in the San Francisco Bay Area. As the leading MMR developer, Hadron Energy is building factory-produced, transportable microreactors that provide 24/7 carbon-free power for data centers, government facilities, industrial sites, and remote communities. Our mission is to create a brighter, healthier, and more equitable energy future.
Role Description This is a full-time on-site role for a Nuclear Engineer, based in the San Francisco Bay Area. The position is ideal for candidates with technical expertise who are passionate about advancing safe, scalable nuclear technology. This is a general application for our Nuclear Engineering team and may evolve into a more specialized position based on candidate strengths and company needs.
You will work closely with our cross-functional team—including mechanical, electrical, and regulatory engineers—to support the design, analysis, and safety development of Hadron’s micro modular reactor. The role spans both core reactor physics and balance-of-plant engineering, with opportunities for hands-on design and innovation in a fast-paced startup environment.
