Radiant is seeking a Principal or Staff Electrical Engineer to define and lead the electrical architecture for Kaleidos, our commercial microreactor targeted for customer deployment in 2028. The work spans end-to-end PCB development, mixed-signal design, high-speed interfaces, power distribution, and signal integrity for the data acquisition, signal conditioning, and real-time processing that reactor control depends on.

Own the multilayer mixed-signal boards that control a fission reactor, terrestrial today with space applications ahead.

Define the system-level electrical architecture for mixed-signal systems: power distribution, analog front ends, and digital control interfaces.

Design, analyze, and simulate low-noise analog front ends and integrate them with ADC/DAC, DSP, and digital subsystems.

Own schematic capture, component selection, and layout, including high-speed and precision routing for sensor interfaces, data acquisition, and communication buses, with focus on signal integrity, power integrity, grounding, and EMI/EMC.

Bring up, debug, and validate hardware hands-on, and write and execute the qualification plans that prove performance, reliability, and environmental margin.

Work directly with firmware, FPGA, and DSP engineers at the hardware-software boundary, and with customers and interdisciplinary teams.

Lead design reviews, mentor the electrical team, and own hardware risk identification and mitigation.
