What are the responsibilities and job description for the Senior RF Antenna Engineer position at Commonwealth Fusion Systems?
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 working with policymakers and suppliers to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.
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 Senior RF Antenna Engineer
SPARC will sustain fusion reactions by feeding >25MW of RF power into the tokamak to heat the plasma to 100 million Kelvin. We need an outstanding RF engineer to build the most powerful Ion Cyclotron Resonant Heating (ICRH) system in the world.
Your responsibilities will include modelling, integration, test, and troubleshooting of all elements of the SPARC RF antenna system.
