About The Position

As the Principal Propulsion Engineer - Ground Fluids, you will serve as the technical authority for our ground fluid systems, the backbone of every mission we fly. You'll be setting the strategy, writing the standards and building the infrastructure that gets Varda spacecraft off the ground and into orbit. You'll own the full lifecycle of ground fluid systems, from architecture and design through build, test and live flight operations. You'll lead propellant loading campaigns across multiple sites, define our operational approach as we scale and serve as the technical subject matter expert for the broader propulsion team.
