Job summary

Radiant is seeking a Senior Electrical Engineer to lead PCB development for a transportable nuclear microreactor. You will own mixed-signal board design, high-speed interfaces, and power distribution to support reactor control hardware in harsh terrestrial and future space environments.

You’ll collaborate with firmware, FPGA, DSP, and software teams, overseeing schematic capture, layout, bring-up, testing, and qualification. 5+ years of PCB experience and a EE degree are required.

Qualifications

• Bachelor’s degree in Electrical Engineering or a related field.
• 5+ years designing custom PCBs, including multilayer and mixed-signal boards.
• Experience delivering hardware from schematic to production or field deployment.
• Experience with schematic capture and PCB layout tools, specifically Altium.
• Hands-on experience with board bring-up, debugging, and lab instrumentation (oscilloscopes, spectrum analyzers, VNAs).

Responsibilities

• Own the PCB design that controls a micro nuclear reactor.
• Design multilayer mixed-signal PCBAs for reactor control and instrumentation that operate in harsh environments.
• Design low-noise analog front-end circuits and integrate them with ADC and digital subsystems.
• Own schematic capture, component selection, performance analysis, placement, layout, fabrication, and assembly.
• Design boards with high-speed communication, sensor interfaces, data acquisition, and EMI/EMC mitigation for nuclear use.
• Bring up, debug, and validate hardware through board-level testing and root-cause analysis.
• Write and execute validation and qualification plans and present in design reviews.
• Work with firmware, FPGA, DSP, and software engineers at the hardware-software boundary.
