Senior Electrical Engineer, PCB

The role

This person will own the design, development, and delivery of mission-critical PCBs for micro nuclear reactor control systems. They will design multilayer mixed-signal PCBAs, analog front-end circuits, and high-speed communication boards.

What you will do

• Own the PCB design that controls a micro nuclear reactor.
• Design multilayer mixed-signal PCBAs for reactor control and instrumentation.
• 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 including high-speed communication, sensor interfaces, data acquisition paths, and communication buses.
• Bring up, debug, and validate hardware through board-level testing, instrumentation, and root-cause analysis.
• Write and execute validation and qualification plans.
• Work directly with firmware, FPGA, DSP, and software engineers.

Required qualifications

• Bachelor’s degree in Electrical Engineering or a related field.
• 5+ years designing custom PCBs, including multilayer and mixed-signal boards.
• Prior experience delivering hardware from schematic capture through layout, assembly, bring-up, and qualification into 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).
• Must be willing to work extended hours and weekends as necessary.
• Must work 100% onsite at El Segundo HQ.

Nice to have

• Master’s degree in Electrical Engineering or a related field.
• Experience in signal integrity, power integrity, grounding strategies, and EMI/EMC mitigation.
• Analog and mixed-signal design experience, including sensor interfaces, ADC/DAC integration, low-noise practices, and high-speed interfaces (SPI, I2C, UART, Ethernet).
• Experience designing for high-reliability or harsh environments (nuclear, aerospace, defense, or industrial), including radiation effects and radiation-tolerant design.
• Experience with FPGA or microprocessor PCBs and embedded systems supporting hardware/software co-design.
• Experience with power electronics or power distribution design.
• Familiarity with nuclear instrumentation or detector interface electronics.
• Experience with electronics production and bring-up.

Benefits

• Substantial incentive stock plan for all full-time employees.
• Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans.
• One Medical: Sponsored memberships for employees and their dependents.
• Vision: 100% top tier plan coverage + 50% for dependents.
• Dental: 100% top tier plan coverage, orthodontia extra, 50% for dependents.
• Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits.
• 8-weeks of paid parental leave for all parents.
• Additional paid pregnancy leave for CA employees.
• Nuclear Engineering Certificate Program: 100% covered educational program with Penn State University, for eligible employees.
• Daily catered lunch.
• Free snacks and drinks.
• Flexible PTO policy.
