Enterprise Systems Implementation Specialist

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.

Radiant is seeking a Business Systems Implementation Analyst to support the Manager of Business Systems and accelerate the company’s Digital Transformation initiative. This role focuses on enterprise system evaluation, implementation, configuration, and rollout, with a strong emphasis on ERP and manufacturing‑adjacent systems (Finance, Supply Chain, WMS, MES).

• Support the development and execution of Radiant’s Digital Transformation roadmap, with a focus on system implementation and adoption.
• Lead detailed current‑state and future‑state process mapping across Finance, Supply Chain, Manufacturing, and Operations.
• Translate business workflows into system requirements, configuration specifications, and rollout plans.

Serve as a core contributor to ERP and enterprise system implementations, including:

• System evaluation and down‑selection
• Configuration and integration planning
• Data migration support
• User acceptance testing (UAT)
• Go‑live and stabilization support

Partner with system administrators, IT, internal stakeholders and vendors to ensure solutions are scalable, compliant, and well‑integrated.

• Support implementation of systems that enable:
• Financial controls and reconciliation
• Inventory and materials management
• Purchasing and sourcing workflows
• Manufacturing execution and traceability

Ensure systems align with manufacturing realities, not just theoretical process models.

• Act as a bridge between:
• Business stakeholders (Finance, Ops, Supply Chain)
• Technical teams (IT, Data Engineering, System Admins)
• External vendors and implementation partners

Ensure stakeholders are aligned on scope, tradeoffs, timelines, and adoption expectations.

• Produce clear documentation including:
• Process flows
• System requirements
• Configuration decisions
• Training materials and SOPs

Support user training and change management to drive successful adoption.

• Documented enterprise business processes and system requirements
• Contribution to enterprise system down‑selection and business cases
• Successful ERP / enterprise system implementations and rollouts
• Improved workflow automation and reduced manual processes
• Clear handoff to system administrators and operations teams post‑implementation

• Bachelor’s degree in Business Administration, Information Systems, Engineering, or related field
• 4–7 years of experience supporting or leading enterprise system implementations
• Hands‑on experience with ERP systems (Finance, Purchasing, Inventory); manufacturing experience strongly preferred
• Experience operating in highly regulated environments (nuclear, aerospace, defense, medical device, or industrial manufacturing)
• Strong ability to translate business processes into system requirements and configurations
• Excellent communication skills and comfort working cross‑functionally

• ERP implementation experience in a manufacturing environment
• Exposure to MES, WMS, or supply chain systems
• Experience supporting system rollouts across multiple departments
• Familiarity with lean manufacturing or continuous improvement concepts
• Technical literacy sufficient to collaborate with IT and data teams (no coding required)
