Responsibilities
Lead the design, execution, and continuous optimization of lithium-metal anode fabrication processes (deposition, lamination, rolling, coating, and post-treatment) to achieve uniform ultra-thin Li layers with excellent adhesion and dendrite suppression
Own cathode material integration (LFP/LMFP, or next-gen chemistries) into lithium-metal cell platforms, including slurry formulation, coating, calendaring, and defect reduction
Develop and scale prelithiation and SEI-engineering strategies to maximize first-cycle efficiency and cycle life in full pouch cells
Drive cell manufacturing process development: electrode stacking/winding, electrolyte filling, formation cycling protocols, and final sealing – with a constant focus on yield, safety, and cost-per-kWh
Build and maintain statistical process control (SPC) systems, design of experiments (DOE), and real-time data analytics to rapidly identify and eliminate process bottlenecks
Troubleshoot complex materials and cell failure modes using advanced characterization tools (SEM, XRD, XPS, EIS, ICP, etc.) and translate root-cause findings into robust engineering solutions
Collaborate daily with R&D scientists, equipment engineers, and operations teams to transfer processes from lab to pilot to commercial scale
Author and own SOPs, PFMEAs, and control plans for all new processes; train technicians and enforce rigorous safety standards in lithium-metal handling environments
Support customer sampling and qualification by building prototype cells that consistently hit energy-density, cycle-life, and fast-charge targets
Actively contributes to IP generation and protection of Pure Lithium’s core lithium-metal platform technologies
