Senior Electrical Engineer, Radiant Nuclear

• Bachelor’s degree in Electrical Engineering or a related field
• 5+ years of experience designing custom PCBs, including multilayer and mixed-signal boards
• Strong experience with schematic capture and PCB layout tools (e.g., Altium, Cadence, or similar)
• Solid understanding of signal integrity, power integrity, grounding strategies, and EMI/EMC mitigation techniques
• Experience with analog and mixed-signal design, including sensor interfaces, ADC/DAC integration, and low-noise design practices
• Familiarity with high-speed interfaces (e.g., SPI, I2C, UART, Ethernet) and layout constraints
• Hands-on experience with board bring-up, debugging, and lab instrumentation (oscilloscopes, spectrum analyzers, VNAs, etc.)
• Ability to work across disciplines and support system integration in a complex engineering environment
• Must be willing to work extended hours and weekends as necessary to accomplish our mission
• Must work 100% onsite at El Segundo HQ

Desirable

• Radiant is seeking a Senior Electrical Engineer with a strong focus on PCB design to lead the electrical architecture for terrestrial reactor control systems, with a long-term path toward space reactor applications
• You will serve as the technical authority for custom hardware, owning the design and development of high-reliability, low-noise printed circuit boards - from requirements definition and schematic capture through layout, bring-up, validation, and field deployment
• This role emphasizes full-stack PCB development, including mixed-signal design, high-speed interfaces, power distribution, and signal integrity, while supporting data acquisition, signal conditioning, estimation, and real-time processing functions critical to reactor control
• Own the design and development of multilayer PCBs for reactor control and instrumentation systems (terrestrial, with future space applications)
• Define electrical architecture for mixed-signal systems, including power distribution, analog front ends, and digital control interfaces
• Design low-noise analog front-end circuits and ensure robust integration with ADC/DAC and digital subsystems
• Perform schematic capture, component selection, and PCB layout with focus on signal integrity, power integrity, grounding, and EMI/EMC mitigation
• Develop and review high-speed, high-precision layouts (e.g., sensor interfaces, data-acquisition paths, communication buses)
• Bring up, debug, and validate hardware, including board-level testing, instrumentation, and root-cause analysis
• Create and execute hardware validation and qualification test plans for performance, reliability, and environmental conditions
• Collaborate cross-functionally with firmware, FPGA, DSP, and responsible engineers to ensure seamless hardware/software integration
