Onsite
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 Permitting Manager to own the final, on-the-ground step for operating an advanced microreactor: securing the state and local permits required to deploy Kaleidos at customer sites. This role is highly hands-on and execution-focused, translating policy and licensing groundwork into permits in hand. You will prepare and file permit applications, and coordinating tightly with the teams that make deployment possible.
Responsibilities & Duties:
Own the end-to-end state and local permitting process for reactor transportation and deployment, from application through approval, ensuring Radiant is consistently getting faster and more effective at securing permits.
Manage relationships with contractors and consultants engaged to support permit applications, site work, and inspections.
Interface with Radiant's regulatory affairs, engineering, legal, and operations teams to ensure permit applications reflect accurate technical and site-specific information.
Interface with Radiant’s community engagement team to ensure strong local understanding and support.
Work directly with our customer’s permitting teams.
Support state and federal policy teams with on-the-ground information, to scope policy suggestions and requests and provide input to advocacy.
Track permit status and requirements across active and prospective deployment sites; flag risks or delays early to leadership.
Build repeatable permitting processes and playbooks to reduce time-to-permit as Radiant scales to new states and sites.
Maintain working knowledge of local and state permitting requirements (transportation, siting, zoning, environmental, construction) relevant to reactor deployment.
Support site selection efforts with permitting feasibility input, in partnership with leadership.
Required Qualifications & Skills:
5+ years of experience managing permitting processes for industrial, energy, infrastructure, or other highly regulated facility projects.
Proven experience managing contractors and/or consultants through a permitting or entitlement process.
Strong understanding of local and state permitting environments (zoning, siting, environmental review, construction permits).
Comfortable operating in ambiguity, working state-by-state without established precedent. Able to define State and Local permitting requirements independently, without primary reliance on support from large consultancies.
Clear communicator able to work equally well with customers, contractors, consultants, and internal technical teams.
Desired Qualifications & Skills:
Experience with permitting for energy generation assets (nuclear, or other power generation).
Experience with permitting on military installations.
Experience with oversize load transportation across state boundaries.
Familiarity with the regulatory/licensing process that precedes permitting (NRC licensing, state PUC processes).
Experience supporting first-of-a-kind or novel infrastructure deployments.
Additional Requirements:
Must be willing to work extended hours and weekends as necessary to accomplish our mission.
Must work 100% onsite in either Washington, D.C. or El Segundo, CA.
