Join the power movement as a Senior Subassemblies Specialist The Subassemblies team is responsible for delivering precision, ultra high vacuum subassemblies for seven major teams that go into the SPARC Tokamak. As a Subassemblies Specialist, you will be the last set of hands and eyes on critical parts; as such, meticulous attention to detail in build quality is necessary. You will draw upon your years of technical experience building complex systems to help streamline workflows and deliver the best possible parts. Once all the subassemblies are built (roughly a two year timeline) you will be uniquely qualified to install the subassemblies into the Tokamak and your role will transition to the Assembly of the machine. This role is truly a once in a lifetime opportunity to use hands-on assembly skills to accelerate the development of fusion energy by ensuring SPARC is built on time and to high quality. The main systems you will be building are high power RF antennas, plasma facing components, port plugs, error field correction coils, vertical stability coils and plasma diagnostics; the bespoke tools used for real-time control of a burning plasma and to achieve SPARC's science mission.
