ERP Implementation Specialist

We are looking for an ERP Implementation Specialist with 4–8 years of experience to own the end-to-end implementation of a new enterprise resource planning system at Radiant Nuclear — the company building the world's first mass-produced portable nuclear microreactor. This is a rare opportunity to join a Series D, $1.8B+ valued startup at a critical inflection point: the ERP platform is being selected now, and this person will be the driving force behind getting it live.

You'll work directly with cross-functional teams across supply chain, finance, engineering, and operations to translate real manufacturing workflows into scalable system solutions. If you thrive in fast-paced, high-stakes environments and want your work to directly support the future of clean, portable nuclear energy — this role is for you.

What will you be doing?

- Lead the full ERP implementation lifecycle — from vendor negotiations and requirements gathering with end users across all departments, to configuration, customization, testing, and go-live.

- Partner daily with stakeholders across supply chain, finance, engineering, and operations to capture what each team needs from the system and translate that into actionable build requirements.

- Coordinate with software engineers on system customizations, integrations, and any technical build-outs required to support the implementation.

- Own training and live support — getting every team up to speed on the new system and providing ongoing support as the organization scales.

- Drive process standardization and reporting, building dashboards and workflows that give leadership visibility into manufacturing performance, inventory, and operational readiness.
