About the company:

Hexium is an energy technology company focused on advancing isotope enrichment through Atomic Vapor Laser Isotope Separation (AVLIS), a laser-driven process that selectively ionizes and separates specific isotopes from a vaporized metal stream. The company is beginning with lithium enrichment and aims to expand into a broad range of isotopes critical for clean energy, nuclear medicine, and advanced industrial applications. Hexium positions itself as a key enabler of the nuclear renaissance by providing enriched materials needed for next-generation nuclear reactors and related technologies. Hexium's mission aligns with sustainability and climate goals by developing a cleaner alternative to conventional isotope separation methods such as centrifuge-based or chemical separation processes. Their AVLIS approach produces no hazardous waste, eliminates the need for complex mechanical systems or costly chemical agents, and offers a compact, scalable footprint. This low-waste profile makes the technology particularly relevant for green energy supply chains, including the production of lithium isotopes used in advanced nuclear fuel cycles and battery-related applications. What differentiates Hexium is its patent-pending modernization of AVLIS technology, which was previously de-risked at pilot scale through over two billion dollars in U.S. Department of Energy investment. By leveraging existing supply chain infrastructure and modern laser designs, Hexium aims to achieve commercially viable capital and operating costs. The platform's adaptability across multiple isotopes positions the company as a flexible supplier for high-impact sectors at the intersection of nuclear energy, medicine, and industrial innovation.

As Hexium advances from laboratory demonstration toward commercial deployment, strong federal partnerships will be essential to accelerating commercialization, securing strategic investment, and supporting the deployment of our technology. 

The Vice President of Government Affairs reports directly to the CEO and leads Hexium's federal engagement strategy. Working closely with the executive leadership team, you'll build trusted relationships across the Department of Energy (DOE), National Nuclear Security Administration (NNSA), Nuclear Regulatory Commission (NRC), Congress, and other key federal stakeholders while advancing government partnerships and strategic funding opportunities that support the company's long-term objectives. 

This is a strategic leadership role that combines government affairs, federal partnerships, and commercialization strategy to help position Hexium as a trusted long-term partner in strengthening America's nuclear fuel cycle.
