We are a small, focused team of engineers, physicists, and operators building hardware at the frontier of what is technically possible. If you want to work on hard problems that matter — directed energy, high-power RF, plasma systems — this is the place.
We work in person, primarily in Southern California. We move fast, own our domains, and build things that get deployed.
