Job description

About Commonwealth Fusion Systems:
Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.
Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.
If that’s you and this role fits, we want to hear from you.
Join the power movement as a Staff OT/IT Support Engineer

We are looking for a versatile, hands-on Staff OT/IT Engineer to join our team at our Milpitas site. This is a hands-on autonomous role split between managing shop-floor OT infrastructure and site wide IT infrastructure. You will serve as the primary on-site technical point of contact, ensuring our engineers, technicians, and operations teams have reliable, high-performing secure systems, while also maintaining and scaling the physical network and compute infrastructure that powers our testing and manufacturing operations (Operational Technology / OT).


If you thrive in high-tempo environments, are able to take ownership of unfamiliar tasks and see them through to completion, where no two days are the same, equally comfortable running cables, configuring network switches on the shop floor or or spotting something that doesn’t look right and escalating it to the security team, this is the role for you.
