Scale Operator Jobs in Montclair, CA (NOW HIRING)

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world's lowest-cost enrichment services, here in the US.

In the process, we are restoring America's ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive.

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society.

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.

We are a mission-driven company with a culture of urgency, accountability, and transparency.

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.

About This Role

As a Plant Operator at General Matter, you will operate and monitor our uranium enrichment systems, ensuring safe, reliable, and compliant operations. You'll work hands-on with cutting-edge enrichment equipment in a fast-paced R&D environment where you'll see systems being built and commissioned from the ground up. This is not a typical "legacy facility" operator role - you'll interface directly with engineers, chemists, and technical teams as we scale our operations, and your input and attention to detail will directly impact our ability to deliver low-cost nuclear fuel safely at scale. You'll work rotating shifts in a highly regulated, safety-first environment handling nuclear materials, and you'll be part of a mission to restore America's enrichment capacity and enable the nuclear Renaissance. If you're an industrial operator - whether from chemical plants, refineries, the Navy nuclear program, or other high-hazard operations - and you're looking for work with real mission and impact, we encourage you to apply.

• Strong attention to detail and ability to follow written procedures and safety protocols with precision
• Demonstrated reliability, accountability, and safety-conscious mindset
• Ability to obtain and maintain required security clearance and access authorization for work with nuclear materials (U.S. citizenship required)
• Willingness to work rotating shifts (days, evenings, nights) including weekends and holidays
• Ability to work on-site in Paducah, KY or Los Angeles, CA
• Ability to wear personal protective equipment (PPE) and work in industrial environments

Preferred Skills and Experience

• Navy nuclear training (submarine or aircraft carrier propulsion plant operations) or other military technical training
• Experience in highly regulated industries (NRC, DOE, FDA/GMP, EPA, or similar)
• Familiarity with lockout/tagout (LOTO), confined space entry, or hazardous material handling procedures
• Experience working in startup, commissioning, or R&D environments where flexibility and problem-solving are valued
• Active or prior security clearance (DOE Q/L clearance or DOD Secret/Top Secret)
• Associate's degree in Process Technology, Industrial Operations, or related technical field
• Prior experience in nuclear facilities, enrichment plants, fuel fabrication operations, or handling UF6 (uranium hexafluoride) is a plus but not required
