Battery Manufacturing Technician - Cell Assembly

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 and enables batteries with a Silicon‑dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Our Si anode material is 50% the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low‑cost and long‑range EVs as a first step towards net‑zero sustainability in the near future.

We are looking for a Battery Manufacturing Technician with battery construction, manufacturing, and/or R&D lab experience and programming/coding skills to carry out electrode fabrication, cell assembly, electrochemical testing, and data analysis.

  Ah‑scale electrode rolls following strict specifications.
• Operate complex electrode fabrication machinery on the Pilot Line. Must be comfortable performing some manual tasks such as lifting weights no heavier than 25kg.
• Characterize electrode features and defects using materials analytical techniques such as SEM/EDX, adhesion testing, resistance measurements, etc.
• Clean equipment and tools after electrode production runs in a timely manner.
• Record parameters used and observed in cell/electrode fabrication processes in runsheets.
• With the assistance of the Manufacturing team, characterize cells and battery materials, using both electrochemical methods & materials analytical techniques.
• Report inventory of manufacturing consumables.
• Follow and maintain standard operating procedures (SOPs).
• Comfortable performing manual tasks requiring precision and dexterity.

• Background in cell assembly or R&D lab work is required. Experience working in controlled‑atmosphere dry rooms is preferred.
