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 scaling fast - expanding factory operations, standing up multi-entity structures, and taking on both government and commercial deployments. This role will manage our liability exposure in a centralized manner - owning programs across all teams and building out our risk infrastructure.

As Risk & Compliance Lead, you will build and own Radiant's risk management function from the ground up - mapping exposure across the entire business, optimizing our insurance and other risk-coverage programs (including layered nuclear-related coverage requirements), and identifying / prioritizing / closing gaps before they become findings. You will mature our programs into a proactive, structured risk governance, and you'll be the connective tissue between insurance brokers, legal, operations, IT, security, finance, and regulatory teams.

This is a high-visibility, largely individual-contributor-to-start role reporting directly to the VP of Finance with the mandate to scale into a broader risk function as our footprint grows.

What You'll Own

Risk Mapping & Liability Structuring:

• Build and maintain comprehensive liability mapping across Radiant's entities, business units, and deployment channels (government and commercial).

• Design risk isolation strategies (both contractual and insurance-based) appropriate to Radiant's multi-entity and GOCO/COCO structures.

• Advise leadership on liability implications of new facilities, long-term contracts, entity formations, and market expansion.

Insurance Program Design & Optimization:

• Own end-to-end design, procurement, placement, and renewal of Radiant's insurance program, including Nuclear, Property, General Liability, Auto, Workers' Compensation, D&O, and other applicable lines.

• Manage layered coverage requirements tied to nuclear-related operations, ensuring adequacy, compliance, and cost-efficiency.

• Continuously evaluate coverage-to-exposure ratios to close gaps and eliminate redundant or underperforming spend, driving improved insurance ROI.

Financial Risk Mgmt & Risk Quantification:

• Develop recommendations based on risk exposure, partnering with Finance on contingency adequacy and reporting.

• Build reporting frameworks and KPIs to provide leadership, Board, investors, and lenders a clear, insightful view of Radiant's risk posture.

Cross-Functional Partnership:

• Serve as the primary bridge between insurance brokers, carriers, legal, operations, IT, security, finance, and regulatory/licensing functions on all matters of risk and compliance.

• Partner with BD on new deployments (government and commercial) to ensure risk and coverage considerations are built in from the start, not retrofitted after the fact.

• Identify and remediate gaps proactively across regulatory and licensing requirements, reducing exposure to gaps and audit-driven contingent liability findings.

• Work closely with our Regulatory Engineering team to own compliance procedures relevant to operations, keeping documentation and processes audit-ready at all times.

Required Qualifications & Skills::

• 8+ years of experience in risk management, insurance brokerage, underwriting, or a related compliance discipline; experience in regulated, multi-entity, or government-contracting environments strongly preferred.

• Bachelor's degree in risk management, finance, or a related field.

• Demonstrated experience designing and procuring insurance programs across multiple lines of coverage.

• Experience with regulatory compliance frameworks; familiarity with NRC requirements or other highly regulated licensing environments is a strong plus.

• Experience structuring liability and risk isolation strategies across multiple legal entities (e.g., GOCO/COCO structures).

• Experience quantifying risk exposure and developing contingency reserve recommendations, with working knowledge of relevant accounting principles (GAAP/statutory) as they apply to risk and insurance.

Additional Requirements:

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.

• Must work 100% onsite at El Segundo HQ.
