Job summary

We are recruiting a design and development engineer for the high-power microwave sources (Gyrotron) and its plasma heating system in our technology development division. We believe that early realization of nuclear fusion will contribute to decarbonization. We will build a strong presence in the experimental nuclear fusion reactor market, aiming to establish the nuclear fusion as a dominant industry in Japan. Our business is being rapidly expanded. We have already received orders for large-scale projects from start-ups and government-affiliated research institution aiming to build the experimental nuclear fusion reactors. We are seeking dedicated individuals who will be involved in our future R&D and business operations which are key to growth.
