Senior Design Engineer - Neutral Beams

About TAE Technologies

TAE is the world's first private fusion energy company, founded in 1998 to commercialize the cleanest, safest, most affordable, and sustainable form of carbon-free power. We are applying science and engineering to design transformational technologies — whether harnessing fusion through the science of stars, making exponential leaps in power efficiency, or innovating medical care with a novel cancer treatment — turning the promise of science into reality. Our mission: a future where all people have affordable access to reliable, abundant, and environmentally friendly fusion-generated electricity.

We are a diverse team of over 500 engineers, scientists, professionals, Maxwell Prize winners, and big thinkers from more than 40 countries with a track record of delivering on innovative ways science can lead humanity into a brighter era.
