Radiant is seeking a Principal Electrical Engineer to lead the electrical system architecture and test infrastructure for Kaleidos, Radiant’s commercial microreactor unit targeted for deployment in 2028
You will own end-to-end electrical integration, from early architecture and requirements definition through hardware bring-up, testing, and commissioning, and serve as the technical authority, ensuring the electrical and validation systems are ready to support that milestone
Define and own electrical and software integration requirements spanning power distribution, signal conditioning, sensor mapping, actuator interfaces, and device simulation
Own and build out the electrical test infrastructure for Kaleidos, and establish the test environment as a foundational asset to validate the commercial unit ahead of the 2028 deployment target
Establish and maintain communication between hardware, control systems, and software interfaces
Define and drive electrical validation strategy; develop test procedures, methodologies, and best practices
Manage schedule, budget, and vendor management for electrical hardware and integration activities
Optimize test and validation processes; develop tooling and automation to improve efficiency
Support electrical integration across multiple critical systems and subsystems
Lead design reviews and effectively communicate technical decisions to cross-functional stakeholders. (Electrical integration, embedded, software, controls.)
