Radiant
Senior Motor Design Engineer - Electromagnetics
Radiant, El Segundo, California, United States, 90245
Overview
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 failsafe microreactor that can be transported anywhere power is needed and run for up to five years without the need to refuel. 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 approach leverages modern software engineering to rapidly achieve safe, factory‑built microreactors that utilize existing, well‑qualified materials. Founded in 2020, Radiant is on track to test its first reactor next year at the Idaho National Laboratory, with initial customer deliveries beginning in 2028. Responsibilities
Senior Electric Motor Design Engineer will design and develop an alternator for the nuclear‑driven, high‑speed power generator. Responsibilities include but are not limited to the design and analysis of active parts within the high‑speed generator. You will collaborate with engineers cross‑functionally and partner closely with the turbomachinery team developing a system for converting mechanical energy to electrical to be delivered to customers safely and reliably. The successful candidate will own active part design of generators, along with performing analysis, simulation, and component selection. Electromagnetic design of 1MW, high‑speed alternator Development and qualification testing of new electric products Interface with outside vendors manufacturing electric components Hands‑on assembly, rapid prototyping, and integration of high voltage electric motors and generators Required Skills and Qualifications
5+ years of design experience designing high‑voltage and high‑power electric motors and/or generators Fundamental knowledge of permanent magnet electric motors Proficiency in electromagnetic design and analysis software like Ansys MotorCAD and Maxwell or equivalent Experience in design, manufacturing, assembly, and test of electric motors Desired Skills and Qualifications
