Job summary

Radiant is seeking a Senior Electrical Engineer to lead full-stack PCB development for terrestrial reactor control systems, with future space applications. You will define mixed-signal architecture, design multilayer PCBs, and ensure robust signal/power integrity while collaborating with firmware, FPGA, and DSP teams.

You will own hardware bring-up, validation, and qualification, delivering high-reliability boards for a nuclear startup focused on rapid deployment and safety-critical operation at

Qualifications

• Bachelor’s degree in Electrical Engineering or 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 (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.

Responsibilities

• Own the design and development of multilayer PCBs for reactor control and instrumentation systems (terrestrial, with future space applications).
• Define the 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 a focus on signal integrity, power integrity, grounding, and EMI/EMC mitigation.
• Develop and review high-speed and 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.
