Engineering Manager, Integration & Test
About the role
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?
- Building and leading the Integration & Test team, including hiring, mentoring, performance management, technical development, and resource planning
- Architecting the hardware-in-the-loop test system from the ground up, including requirements definition, platform selection, system configuration, and hardware bring-up
- Recreating the reactor control system on a bench by simulating sensors, actuators, signals, and system inputs and outputs
- Owning electrical and software integration requirements across power distribution, signal conditioning, sensor mapping, actuator interfaces, communications, controls, and device simulation
- Partnering with software, controls, simulation, mechanical, and electrical teams to ensure the test environment accurately represents reactor behavior
- Driving the electrical validation strategy, including test procedures, automation tooling, data acquisition, debugging methodologies, and engineering best practices
- Managing schedules, budgets, vendors, and technical risks associated with electrical integration and test infrastructure
- Leading design reviews and communicating technical decisions, tradeoffs, and program status to engineering leadership and executives
