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.
