Responsibilities

Co-own and be the expert in the assembly sequence of your workstation (initially scoped to the assembly of the Toroidal Field Coil (TF) semicircle sub-assemblies), determining and enacting acceptable solutions and changes that fit with the entire SPARC assembly sequence.
Be responsible for new first-encounter work scope definition, including the installation of various manifolds and magnet sub-assemblies.
Determine and execute solutions for identified assembly issues (e.g., fit, method, component handling), collaborating with Tokamak System design teams for modifications.
Proactively procure or build all tools, fixtures, or manipulation equipment required for upcoming process steps in your workstation.
Serve as the owner for a process by testing, implementing, and handing off to production technicians for repeated use.
Provide design feedback to SPARC sub-system designs with a focus on manufacturing and assembly, participating in design reviews.
Assist in the disposition and resolution of non-conformance issues, incorporating red-line changes into updated assembly sequences.
Support hands-on operations during Tokamak Assembly in various roles.
Work collaboratively with teammates to receive feedback and ensure all requirements are met, involving adjacent sub-system experts for high loads, vacuum requirements, and complex manipulation.
