Responsibilities

Station owner working on night hours with start times ranging from 3p to 7p for five nights a week
Owner and expert in the assembly sequence of your work-station, with the responsibility to determine and enact acceptable solutions and changes to the sequence that both allow successful completion of the work-station but also fit with the entire SPARC assembly sequence
Responsible for new first-encounter work scope definition from the large magnet positioning and installs to the precise plasma facing component alignment and adjustment
Determination and execution of solutions for identified assembly issues that arise, such as fit, method, or component handling problems.
Work with the Tokamak System design teams to determine how a part or process step could be modified to work while also meeting functional requirements
Proactively procure or build all tools, fixtures, or manipulation equipment required for the upcoming parts of the process in your work-station
Serve as the extreme owner for a process by testing, implementing, and handing off to production technicians for repeated use for any given operation or tool(s)
Provide design feedback to SPARC sub-system designs with a focus on manufacturing and assembly.
Participate in both formal and informal design reviews to ensure what is delivered can be assembled
Assist in the disposition and resolution of non-conformance issues on parts or the process, then working to incorporate and release red-line changes into an updated assembly sequence
Support hands on operations during Tokamak Assembly serving a variety of roles in the process
Work with teammates in a collaborative fashion to receive feedback early and often to ensure all requirements are met.
Many SPARC projects involve high loads, vacuum requirements, and complex manipulation requiring the involvement and review of adjacent sub system experts
