Senior Electrical Engineer, Integration & Test
About The Position
Radiant is seeking a Senior Electrical Engineer, HIL, to lead design, development, and maintenance of electrical test infrastructure for Kaleidos, its commercial microreactor targeted for deployment in 2028. The engineer will own Hardware-in-the-Loop (HIL) systems and other electrical test platforms, and drive integration and validation across critical systems. The role includes making technical decisions across electrical integration, validation strategy, and test-environment development, supporting the first commercialized high-temperature gas-cooled portable microreactor. The position is 100% onsite at Radiant’s El Segundo headquarters. The engineer must be willing to work extended hours and weekends as necessary. Radiant describes compensation as including base salary, substantial equity grants, and comprehensive health benefits; compensation and level are determined based on interview performance, experience, education, and qualifications.
