Warehouse Manager

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 failsafe microreactor that can be transported anywhere power is needed and run for up to five years without the need to refuel. 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 utilizes modern software engineering to rapidly achieve safe, factory-built microreactors that leverage existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor next year at the Idaho National Laboratory, with initial customer deliveries beginning in 2028.

We are seeking a hands-on Warehouse Manager to build, formalize, and operate our warehouse and material control functions in a regulated nuclear manufacturing environment. This role owns end-to-end warehouse operations—including receiving, inspection, inventory control, kitting, internal material movement, packaging, and shipping—while establishing compliant, auditable processes that support safe, traceable, and scalable production.

This is a foundational role. You will build on an existing operation, document and standardize processes, implement systems and metrics, and continuously improve warehouse performance as production volume and regulatory complexity increase.

• Own all warehouse activities across inbound, internal, and outbound material flow
• Support manufacturing schedules through accurate, timely inventory movement and kitting
• Allocate labor and resources to meet operational and production demands

• Design and evolve the physical warehouse layout, including racking, staging, inspection, and shipping areas
• Establish digital inventory structure, including location control, labeling, serialization, and traceability
• Select, implement, and optimize ERP/WMS tools, barcoding, and inventory controls in alignment with nuclear quality requirements

• Develop and maintain SOPs, work instructions, and training materials
• Ensure warehouse operations meet nuclear quality, safety, and audit-readiness standards
• Identify process gaps and implement compliant improvements

• Maintain high inventory accuracy through disciplined transactions, cycle counts, and controls
• Manage discrepancies, nonconformances, and inventory risk communication
• Establish and track KPIs for receiving, inventory accuracy, and order fulfillment
• Drive lean improvements, reduce waste, and identify automation opportunities
• Hire, train, and lead warehouse personnel as the operation scales
• Foster a culture of accountability, safety, quality, and continuous improvement

• 5+ years of warehouse or materials management experience in a regulated manufacturing environment (nuclear, aerospace, defense preferred)
• Experience building or formalizing warehouse operations, systems, and processes
• Strong knowledge of inventory control, traceability, and production support
• Experience with ERP/MRP and warehouse management systems
• Proven people leadership with a hands‑on, execution‑focused mindset

• A compliant, auditable warehouse supporting nuclear manufacturing
• Accurate, traceable inventory enabling uninterrupted production
• Documented processes, trained staff, and clear performance metrics
• A scalable warehouse foundation ready for future growth

This is an exempt salaried role.
