About Radiant

Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments 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.
