Battery Technician - Electrode Production

Coreshell Technologies•San Leandro, CA

2d•$30 - $35•Onsite

About The Position

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 lower than 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. Position: We are looking for a Battery Technician - Electrode Production with large-scale battery electrode manufacturing and/or electrode process development experience and program language skills to carry out electrode fabrication, data visualization, and process development work. Ideal candidate is self-driven, detail-oriented, proactive in problem solving and able to wear many hats.
