Radiant is seeking a Senior Electrical Engineer, HIL to lead the design, build, and maintenance of Radiant’s electrical test infrastructure for Kaleidos, our commercial microreactor targeted for deployment in 2028. You will own test infrastructure development, including Hardware-in-the-Loop (HIL) systems and other electrical test platforms, and drive integration and validation across critical systems. This role suits an experienced electrical engineer with deep hands-on test-infrastructure expertise, ready to own technical decisions across electrical integration, validation strategy, and test-environment development. You will shape the electrical test infrastructure supporting the first commercialized high-temperature gas-cooled portable microreactor.

Build the HIL platform from the ground up: plant simulation, real hardware-in-the-loop, and the test environment Kaleidos ultimately ships from.

Own the design, build, and maintenance of electrical test infrastructure, including test benches and new test platforms as the program scales.

Define electrical and software integration requirements across power distribution, signal conditioning, sensor mapping, actuator interfaces, and device simulation.

Own the communication layer between hardware, control systems, and software, including protocol selection, timing, and boundary fault behavior.

Lead the electrical validation strategy, developing and iterating the test procedures the program depends on rather than executing someone else’s.

Assemble, debug, and troubleshoot test hardware and harnesses hands-on, with minimal guidance.

Execute test procedures, collect data, and lead analysis across multiple test environments.

Drive automation and tooling improvements, with real influence over how the team tests.

Lead design reviews and carry technical decisions to cross-functional stakeholders.
