Job description

About Radiant

Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028.

• Strong experience with industrial signal types, 4-20mA, RTD, Thermocouples, and Resolvers.

• Experience with high-speed, sensitive signals.

• Experience with digital communication interfaces such as SPI, I2C, CAN, Ethernet, and RS422.

• Experience with EMI/EMC best practices for design and strategies to mitigate exceeding levels.

Desired Qualifications and Skills

• Master’s degree in electrical engineering, physics, aerospace, mechanical, nuclear engineering, or a related field.

• Experience with rad hardened circuit design.

• Experience with control system design for nuclear applications.

• Experience with nuclear instrumentation and signals.

• Experience with applying IEEE-603 in electrical designs.
