Staff Manufacturing Engineer, DFM

The posting, as Radiant Industries wrote it

ABOUT RADIANT

Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments beginning in 2028.

ABOUT THE ROLE

Radiant is seeking a Staff Manufacturing Engineer to help transition Kaleidos from a first-of-a-kind reactor build into a repeatable, scalable production system.

With the initial Kaleidos reactor build complete, Radiant is now applying what we learned through design, fabrication, assembly, integration, and test to the next generation of the product. This includes reducing mass and part count, improving manufacturability and assembly, increasing production repeatability, and developing the processes, tooling, equipment, suppliers, and quality controls required to manufacture reactors at scale.

In this role, you will work closely with design, quality, test, supply chain, and operations engineers to influence hardware from the earliest stages of design through fabrication and final assembly. You will own manufacturing processes for critical reactor components, mechanisms, structures, and integrated assemblies, ensuring designs can be built safely, reliably, and repeatedly while meeting demanding performance and quality requirements.

You will be expected to identify manufacturing constraints early, drive DFM and DFA into the product, develop and qualify production processes, and close the loop between engineering intent and what happens on the factory floor. The ideal candidate is equally comfortable reviewing a CAD model with a design engineer, developing a fixture or manufacturing process, troubleshooting a build issue, working with a supplier, and using production data to improve the next iteration of the product.

This is a hands-on engineering role with significant influence over how Kaleidos evolves from a development program into a manufacturable product.

RESPONSIBILITIES & DUTIES

• Own manufacturing and inspection processes for critical Kaleidos components, mechanisms, structures, and assemblies from design release through fabrication, integration, and final acceptance.
• Partner closely with design engineers to drive design for manufactu
