Job summary

Radiant, an El Segundo, CA-based startup, seeks a Senior Electrical Engineer focused on full-stack PCB development for reactor control hardware. You will own multilayer PCB design, integrate analog/digital subsystems, and ensure signal and power integrity across terrestrial and future space applications.

The role requires bringing up hardware and validating designs in collaboration with firmware, FPGA, and DSP teams.

Qualifications

• 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.

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.
