• Lithium Extrusion & Feeding:
  Operate the lithium extruder to convert bulk lithium ingots into continuous strips. Manage hydraulic pressures, temperature zones, and die alignments to ensure consistent feedstock quality.
• R2R Milling Operations:
  Run the proprietary Roll-to-Roll milling machine to reduce lithium strip thickness to target specifications with high surface quality.
• Independent Dry Room Work:
  Execute daily production runs autonomously in a low-dew-point dry room. You must be comfortable working alone in this environment while adhering to strict safety protocols.
• Equipment Maintenance & Design:
  • Perform routine maintenance on both the extruder (hydraulics, dies) and the R2R mill (rollers, tensioners).
  • Use CAD (Solid Works/AutoCAD) to design and implement improvements for material feeding, scrap collection, or die modifications.
• Data Analysis (Process vs. Performance):
  • Log critical process data (extrusion pressure, roller gaps, resulting foil thickness).
  • Develop Design of Experiments (DOE) to establish the relationship between process variables and electrochemical performance
  • Correlate mechanical process data with downstream battery cycle life and efficiency to identify optimal operating windows.
• Chemical Safety:
  Safely handle metallic lithium, perform waste disposal, and maintain a safe workspace according to EHS standards.

• Education:
  
  BS or MS in Mechanical Engineering, Manufacturing Engineering, or Materials Science.
• Note:
  
  Candidates must demonstrate strong mechanical aptitude regardless of major.
• Experience:
  
  BS with a minimum of 5 years of experience or a MS with a minimum of 3 years of experience in relevant hardware, manufacturing, or R&D lab environment.
• Required Skills:
  • Experience with Extrusion processes (polymer, metal, or even ceramic).
  • Familiarity with Roll-to-Roll (web handling) processing.
  • Mechanical Hands-on:
    Experience with machinery involving pressure, hydraulics, or moving webs/rollers.
  • Data Literacy:
    Ability to interpret voltage curves, capacity retention charts, and basic statistical data.
  • CAD Proficiency:
    Ability to design simple fixtures or modify machine parts.
• Work Environment:
  Willingness to work in a Dry Room environment and wear PPE for extended periods.

• Knowledge of hydraulics and high-pressure systems.
• Experience handling alkali metals (Lithium/Sodium).
