We are looking for an Engineering Manager, Integration & Test with 8+ years of electrical engineering experience and at least 2 years of people-management experience to build and lead the team responsible for validating Radiant’s commercial microreactor, Kaleidos. You will establish the Integration & Test function from the ground up, manage a small team of electrical engineers, and remain deeply involved in the architecture and development of the hardware-in-the-loop test environment.
This is a hands-on frontline management role for a technical leader who can build both the system and the team. You will define how the complete reactor control system is represented in the lab, establish validation processes, and align electrical, software, controls, and simulation teams around a common test platform. Your team’s infrastructure will be foundational to validating Kaleidos ahead of its targeted commercial deployment in 2028.
What will you be doing?
