Battery Manufacturing Technician - Front End

Position: Battery Manufacturing Technician - Front End

Reports To: Senior Battery Engineer

Coreshell’s metallurgical Silicon anode technology delivers high capacity, fast‑charging, and superior safety. Our low‑cost liquid‑phase nano‑coating addresses critical electrode‑surface degradation issues, enabling batteries with a Silicon‑dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs.

We are looking for a Battery Manufacturing Technician with battery production, manufacturing, and/or R&D lab experience to join the slurry production team on Coreshell’s Pilot Line. The ideal candidate is detail‑oriented, capable of troubleshooting problems, and can start before 8 am on up to two days a week.

• Mix 50‑L‑scale slurries using Pilot Line scale machinery; perform manual tasks such as lifting weights no heavier than 25 kg.
• Conduct guided experiments to define optimal process parameters for cell performance and processing capabilities.
• Perform routine quality‑control tests using various material characterization tools.
• Clean mixing equipment and tools promptly after slurry production runs.
• Manage inventory of manufacturing consumables.
• Maintain a safe, tidy, and organized work area.
• Follow and maintain standard operating procedures (SOPs).

• Background in manufacturing work is required. Experience with Li‑ion battery fabrication and/or mixing processes is a plus.
• Previous laboratory work experience.
• Familiarity with chemistry lab safety protocols.

2+ years of experience in manufacturing or battery industry OR a B.S. degree or equivalent in Chemistry, Materials Science, Engineering, or a similarly relevant field.
