Warehouse Manager

El Segundo, California, United States

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.

Warehouse Manager

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.

  • 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

Compliance, Documentation & Quality

  • 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

Inventory Accuracy & Performance

  • 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

Continuous Improvement & Leadership

  • 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

Qualifications

  • 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

What Success Looks Like

  • 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.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
