Software Engineer

Radiant Industries is a n El Segundo, CA -based startup developing Kaleidos, a portable, containerized nuclear microreactor . Portable nuclear power with rapid deploy capability can replace diesel generators used today to provide critical asset support for hospitals, datacenters, and military bases or to power microgrids at remote sites . Radiant ’s unique, practical approach to nuclear development utilizes modern software engineering to rapidly achieve safe, factory-constructable microreactors leveraging existing , well-qualified materials . Radiant is on a fast track to demonstrate the first fueled operation of a new commercial nuclear reactor design , just two years from now.

Software Engineer (Thermal Modeling)

The Digital Twin software team is seeking a driven simulation software engineer with expertise in thermal modeling and analysis. The Digital Twin is an innovative real-time simulation system for Kaleidos, spanning from core physics simulation to connecting real hardware and validating performance. This is a critical system utilized by every engineering team in the organization to enable rapid iteration and model safety critical scenarios.
