Senior RF Test Engineer

SPARC sustains fusion reactions by feeding >25MW of 120MHz RF power into the tokamak to heat the plasma to 100 million Kelvin. We need an RF Test Engineer to play a pivotal role in validating and testing the electronics and control systems that power the most ambitious RF plant in the world.

At this level, you are a hands-on executor and technical problem solver. You will be directly responsible for taking newly architected RF and power electronics from the benchtop to full-scale operation. Your day-to-day will span board-level bring-up, operating high-power RF transmitters, and integrating hardware with software controls to ensure SPARC achieves net energy.
