About the Role

Radiant is seeking an Entry-Level Electrical Engineer with a focus on PCB design to support the development of electrical systems for terrestrial reactor control, with a long-term path toward space reactor applications. In this role, you will work closely with senior engineers to design, build, and test high-reliability, low-noise printed circuit boards used in reactor instrumentation and control systems.

You will contribute across the full PCB development lifecycle—from schematic capture and layout to bring-up and validation—while gaining hands-on experience with mixed-signal systems, data acquisition, and real-time control hardware. This is an excellent opportunity for a motivated engineer to develop deep expertise in PCB design, signal integrity, and hardware development in a highly technical, mission-critical environment.

Responsibilities and Duties

• Support the design and development of multilayer PCBs for reactor control and instrumentation systems.

• Assist with schematic capture, component selection, and PCB layout under guidance from senior engineers.

• Contribute to mixed-signal designs, including analog front ends, power distribution, and digital interfaces.

• Apply best practices for signal integrity, power integrity, grounding, and EMI/EMC considerations in layouts.

• Participate in board bring-up, debugging, and lab testing using standard instrumentation (e.g., oscilloscopes, multimeters).

• Help execute hardware validation and test plans, including functional and performance testing.

• Collaborate with firmware, FPGA, DSP, and responsible engineers to support hardware/software integration.

• Document designs, test results, and engineering changes clearly and thoroughly.

Required Qualifications and Skills

• Bachelor’s degree in Electrical Engineering or a related field.

• Internship, academic project, or hands-on experience with PCB design or electronics development.

• Familiarity with schematic capture and PCB layout tools (e.g., Altium, Cadence, KiCad, or similar).

• Basic understanding of analog and digital circuits, including common interfaces (SPI, I2C, UART).

• Foundational knowledge of signal integrity, grounding, and noise considerations.

• Experience working in a lab environment and using basic test equipment.

• Strong problem-solving skills and willingness to learn in a fast-paced engineering environment.

Desired Qualifications and Skills

• Exposure to mixed-signal or low-noise circuit design through coursework or projects.

• Experience with PCB layout for multilayer boards or high-speed signals (academic or internship).

• Familiarity with embedded systems, microcontrollers, or FPGA basics.

• Interest in high-reliability or regulated industries (nuclear, aerospace, defense, or industrial systems).

• Understanding of basic design for manufacturability (DFM) and design for test (DFT) concepts.

Additional Requirements

• Must be willing to work extended hours and weekends as necessary to accomplish our mission

• Must work 100% onsite at El Segundo HQ

Benefits and Perks

• Stock: 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.

• Daily catered lunch. Free snacks and drinks.

• Flexible PTO policy. Remote workday allocation.

• Company and team-bonding events, happy hours and in-person camaraderie.

• Beautiful El Segundo headquarters close to the Pacific Ocean.
