We are seeking an Engineer to design and develop high pressure systems for filling inertial fusion energy (IFE) targets with high pressure gas. This will span prototypes to mass production systems where target throughput is at a few Hertz rate. Fill pressures in the range of two to three hundred atmospheres are expected. Mechanisms operating in this pressure environment are anticipated. The filling system will form a key component for fueling the Inertia fusion power plant.
