HVM Development•Process Owner for post processing steps (Heat Treatment/Annealing, Slitting, Lamination) in the manufacturing of 2G High Temperature Superconducting wire.•In-charge of designing process plans, develop process recipe, DOE’s to establish CTQ limits and meet the daily production targets. Involved in the entire equipment build phase to ensure and implement the process specifications. •Provided technical leadership in continuous improvement projects to improve efficiency, volume, quality & safety.•Collaborated with different organizational teams such as Engineering, Operations, Marketing and R&D to develop the first of a kind High-Volume Manufacturing line of 2G HTS tape via determining product specifications, QC checkpoints, developing process flow and lean manufacturing route.•Engaged in a $2.5M project with equipment vendors to source and build various Reel to Reel QC tools for each process in the manufacturing line to track and ensure the product quality throughout the process flow.•Supervised a team of technicians and operators by training and guiding them to drive the material characterization.•Developed, implemented, and monitored the radiation safety policy and program. Performed the duties as RSO to ensure the personnel safety and regulatory compliance.Technology Development•In-charge of delivering product KPIs through developing first of a kind Destructive Physical Testing (Single/ Double bending, Critical axial and tensile stress, Torsional strength, Thermal cycling, Hermeticity) and Electro-magnetic (self-field, In-field, non-contact) methods to solidify the customer needs. •Planned budget, workforce, timeline and executed successfully in building R2R Method development station that is used to test several metrology equipment that characterize the 2G HTS tape.
