Staff Manufacturing Engineer (DFM)

Join Radiant, a cutting-edge company focused on revolutionizing energy production. As a Staff Manufacturing Engineer, you will play a crucial role in transitioning our innovative Kaleidos reactor from a prototype to a scalable production system. You will work closely with various engineering teams, own manufacturing processes for critical reactor components, and drive design for manufacturability and assembly. This hands-on engineering role offers significant influence over the evolution of our product and the opportunity to make a meaningful impact in the energy industry.
