## Job description

## 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

We are seeking an experienced Radiation Safety Officer/Radiation Protection Manager to lead radiation protection for General Matter's UF6 operations. This role is critical to ensuring the safety of our people and the public, and to maintaining compliance with NRC, DOE, and other applicable radiation safety regulations as we scale enrichment operations in the US.

This person will be responsible for establishing and implementing our radiation protection program end-to-end, and will serve as a key resource in radiation safety management decisions across the organization.

## Responsibilities

- Establish and implement General Matter's radiation protection program, including procedures and processes supporting UF6 handling and enrichment operations
- Ensure compliance with NRC, DOE standards (e.g., 10 CFR Part 20, ICRP, and ANSI)
- Establish and administer ALARA principles, radiation monitoring, dosimetry, and radiological programs and controls to protect workers and the public
- Evaluate radiological instrumentation and monitoring systems to ensure adequacy and compliance with site requirements
- Serve as the site authority on radiation safety, advising operations, engineering, and leadership on radiological considerations and participating as a resource in radiation safety management decisions
- Maintain close familiarity with facility operations to identify and address site-specific radiation protection concerns
- Support licensing and regulatory interactions related to radiation protection
- Develop and deliver training programs to personnel on radiological protection principles, standards, and procedures
- Build and lead the radiation protection function and team over time as operations grow

## Basic Qualifications

- BS/BA or advanced degree (master’s or doctorate) in science or engineering, health physics, radiation protection, or a closely related field.
- 8+ years of experience in radiation protection, health physics, or a closely related field.
- Previous experience as an RSO/Radiation Protection Program Manager at an NRC-licensed facility, DOE site, national laboratory, or comparable regulated nuclear environment
- Relevant certifications or credentials (e.g., NRRPT, CHP)
- Direct experience with uranium (UF6/UO2) processing operations; OR equivalent experience with other highly radioactive or hazardous materials in a regulated environment
- Skilled in interpreting radiation protection data and applicable regulations, including NRC and DOE (e.g., 10 CFR Part 20 and ANSI), and translating requirements into practical procedures
- Ability to obtain and maintain required security clearance and access authorization

## Preferred Skills and Experience

- Evidence of exceptional ability (prior projects, portfolio of work, completed programs, etc.)
- Experience standing up or significantly expanding a radiation protection program, particularly in a fast-paced, resource-constrained, or startup environment
- Advanced degree in health physics, radiation science, or a related field

Additional Requirements

- Ability to work extended hours and weekends as necessary.

## About General Matter

## Core Business
- **Primary industry**: Nuclear energy – uranium enrichment, nuclear fuel supply chain
- **Target customers**: Nuclear power plant operators (civilian reactors, small modular reactors, microreactors), data center operators, industrial manufacturers, and government/defense entities
- **Mission**: “Restore US leadership in nuclear fuel” and “make the cleanest, safest form of baseload energy the most affordable” [generalmatter.com/mission](https://generalmatter.com/mission/)

## Products & Services
- **Low Enriched Uranium (LEU)**: Enrichment of uranium to 3-5% U-235 for existing US civilian reactors (supplying ~20% of US grid power)
- **High Assay Low Enriched Uranium (HALEU)**: Enrichment to 5-20% U-235 for next-generation small modular reactors (SMRs) and microreactors
- **Enrichment as a Service**: Novel, scalable, cost-competitive enrichment technology to fill the critical gap in the US nuclear fuel cycle (conversion → enrichment → deconversion/fabrication)

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: Currently hiring for 64+ roles across engineering, construction, legal, and operations; actively building enrichment capacity
- **Notable Investors/Partners**: Described as backed by “institutions” and “generational companies” – specific names not publicly available [generalmatter.com/careers](https://generalmatter.com/careers/)
- **Growth Signals**: Aggressive hiring across multiple disciplines; establishing a physical presence in Los Angeles (HQ) and Paducah, Kentucky (construction/manufacturing); addressing a critical national security gap (US currently performs <1% of global enrichment)

## Competitive Advantages
- **Domestic enrichment technology**: Novel, proprietary enrichment process designed to be cheaper, more reliable, and scalable compared to foreign state-backed competitors
- **National security moat**: Sole US-focused enrichment startup aiming to break dependence on Russian and Chinese supply chains
- **Talent pool**: Attracts high-caliber individuals from nuclear engineering, technology, finance, and special operations backgrounds
- **First-mover in HALEU**: Positioned to fuel the next wave of advanced reactors and behind-the-meter power for AI data centers

## Strategic Focus
- **Scale domestic enrichment capacity**: Build and operate enrichment facilities in the US (Los Angeles and Paducah)
- **Support AI and manufacturing growth**: Provide reliable, emissions-free baseload power for compute and industrial expansion
- **Enable advanced reactors**: Supply HALEU for SMRs and microreactors, opening new markets in remote and austere environments
- **Strengthen US energy independence**: Restore US leadership in nuclear fuel production

## Why Work Here
- **Culture**: High standards, extreme ownership, copious autonomy, deep trust, zero politics – described as “work with the best across nuclear, tech and finance” [generalmatter.com/careers](https://generalmatter.com/careers/)
- **Work environment**: On-site roles in Los Angeles, CA (engineering, nuclear, legal) and Paducah, KY (construction, procurement); no remote/hybrid options explicitly stated
- **Notable perks**: Mission-driven work with national impact; opportunity to solve a critical energy and security challenge; flat organization with high agency
