Director of Policy and Government Affairs

Job description

## **About Radiant** Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028. **About the Role** Radiant is seeking a **Director of Policy and Government Affairs**, to lead the company’s engagement with Congress and help shape the policy, authorization, and appropriations environment required to deploy microreactors across U.S. government customers. This role sits at the center of Radiant’s federal growth strategy.

Cross-Functional Execution: - Partner closely with business development, policy, regulatory, and technical teams to align congressional strategy with customer needs, capture priorities, and deployment opportunities. - Translate Radiant’s technical capabilities into clear policy, budgetary, and legislative objectives. - Support the development of congressional engagement plans tied to specific programs, accounts, and federal customers. - Provide leadership with clear, actionable insight on legislative dynamics, stakeholder positioning, and emerging opportunities or risks External Affairs & Stakeholder Management: - Coordinate with outside consultants, trade associations, think tanks, and aligned partners in support of Radiant’s policy and legislative priorities. - Support senior executives in congressional meetings, strategic external engagements, and high-priority policy events. - Build relationships across the broader defense, energy, and industrial base ecosystem to strengthen support for advanced nuclear deployment. - Ensure compliance with applicable lobbying, ethics, and disclosure requirements. **Required Qualifications & Skills:** - Bachelor’s degree in a relevant field of study. - 7+ years of experience in congressional policy, appropriations, or government affairs. - Experience working on Capitol Hill or closely with Congress. - Strong understanding of the congressional authorization and appropriations process. Excellent written and verbal communication skills. **Desired Qualifications & Skills:** - Experience working for a congressional appropriations or authorizing committee. - Experience at a government affairs firm or multi-client policy practice. - Familiarity with Department of Defense budgeting and program structure. - Knowledge of nuclear energy, advanced energy technologies, or national security policy. **Additional Requirements:** - Must be willing to work extended hours and weekends as necessary to accomplish our mission. - Must work 100% onsite at our DC office. ## **Benefits and Perks** - Stock: Substantial incentive stock plan for all full-time employees. - Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans. - One Medical: Sponsored memberships for employees and their dependents. - Vision: 100% top tier plan coverage + 50% for dependents. - Dental: 100% top tier plan coverage, orthodontia extra, 50% for dependents. - Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits. - 8-weeks of paid parental leave for all parents.
