• Represent Radiant at regulatory proceedings, industry forums, and government stakeholder meetings

What We're Looking For

• 15+ years of nuclear regulatory affairs, nuclear licensing, or senior-level government and regulatory experience in highly regulated industries
• Demonstrated expertise in NRC regulations, nuclear licensing pathways, and nuclear safety frameworks
• Proven success managing complex regulatory approvals in a startup or high-growth, fast-paced environment
• Established relationships and credibility with U.S. nuclear regulators or equivalent federal agency experience
