Nuclear Safety Basis Lead

General Matter, Inc. is an American nuclear energy company based in California that is focused on developing domestic nuclear energy solutions. The company aims to harness nuclear technology to increase national energy prosperity, reduce dependence on foreign energy sources, and support the expansion of American capabilities in the energy sector. Their work centers on making nuclear energy more accessible and practical by advancing technologies that can be developed and deployed within the United States. General Matter's mission is rooted in the belief that nuclear power represents a critical pathway toward a cleaner, more energy-independent future. By turning domestic nuclear potential into operational reality, the company positions itself at the intersection of national security, economic growth, and climate-conscious energy production. Their approach emphasizes building nuclear energy infrastructure that is homegrown rather than reliant on foreign supply chains or expertise. The company brings together leaders from nuclear engineering, technology, government, and finance, reflecting a multidisciplinary approach to solving the complex challenges of modern nuclear energy development. As a startup operating in the green and climate technology sector, General Matter represents a new wave of private investment in nuclear energy as a viable and scalable low-carbon power source for the United States.

About the Company

General Matter is enriching uranium in America. 

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.  

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors. 

Ultimately, our work will help power national ambitions and enable a high-energy society. 

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. 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 Nuclear Safety Basis Lead at General Matter, you'll own the integrated safety basis for a first-of-its-kind enrichment facility — the complete set of analyses, controls, and commitments that establish how the facility is authorized to operate. You'll keep the Integrated Safety Analysis (ISA), management measures, and license conditions consistent and current as the facility designs, builds, and operates, and you'll ensure proposed changes are evaluated for their impact on the safety basis. This is a systems-level leadership role at the center of our licensing strategy: you'll work across engineering, safety, operations, and licensing and interface directly with the NRC on the commitments that let us operate. If your background is in DOE authorization basis work, such as DSAs, TSRs, and Unreviewed Safety Question (USQ) determinations under 10 CFR 830, that experience maps directly onto this role's core structure and is exactly what we're looking for.

Responsibilities

• Own and maintain the facility's safety basis — the integrated ISA, management measures, and license commitments.
• Ensure the authorization basis remains current and internally consistent as the facility evolves.
• Ensure consistency between the license application, ISA Summary, and supporting analyses.
• Lead safety basis reviews and evaluations for proposed design, process, and operational changes.
• Interface with the NRC on license amendments, commitments, and safety basis matters.
• Coordinate across ISA, criticality, consequence, fire, design, and operations teams to maintain a coherent safety basis.
• Lead and mentor staff supporting safety basis development and maintenance.
• Maintain configuration control and documentation to support audits and regulatory reviews.

Basic Qualifications

• Strong understanding of engineering fundamentals.
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information.
• Bachelor's degree in Nuclear Engineering, Chemical Engineering, or a related field.
• Strong knowledge of nuclear safety basis / authorization basis concepts and 10 CFR Part 70, 10 CFR 830, or comparable regulatory framework.
• Experience with safety basis development, maintenance, or change evaluation.
• Experience leading technical teams, projects, or programs.
• Excellent analytical and problem-solving skills.
• Strong verbal and written communication skills, with the ability to convey technical information to diverse audiences.
• Ability to work collaboratively in a team-oriented environment.

Preferred Skills and Experience

• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).
• Experience in a fast-paced engineering environment or a highly technical role requiring a resourceful, entrepreneurial approach to complete tasks within tight timeframes or budget constraints.
• Experience with nuclear fuel cycle facility licensing, or DOE documented safety analysis (DSA) and technical safety requirements (TSRs) — we consider DOE DSA/TSR/USQ experience directly transferable to NRC ISA and management-measure work
• Experience interfacing with the NRC or DOE.
• Advanced degrees.
• Professional Engineer (PE) license is preferred or the ability to obtain one.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
