Coreshell unlocks energy without limits. Backed by Alchemist.
About the role
This Battery Test Engineer role owns the battery testing infrastructure that underpins Coreshell’s cell development and manufacturing operations. You will be responsible for the installation, commissioning, calibration, and ongoing maintenance of all electrochemical test equipment and will serve as the primary point of contact for hardware vendors.
What they're looking for
- Demonstrated experience installing, commissioning, and maintaining battery test equipment at scale, including cyclers, thermal chambers, and environmental test equipment
- Hands-on expertise in calibration and metrology for electrochemical test systems, including voltage/current accuracy verification, thermocouple calibration, and environmental chamber qualification
- Strong understanding of battery test protocols, including formation, characterization (C-rate testing, HPPC, EIS), cycle life, and calendar aging procedures for lithium-ion cells
- Experience managing test data pipelines: ensuring proper data capture from cyclers and auxiliary instruments, implementing metadata standards, and maintaining traceability between manufacturing records and test results
- Experience managing vendor relationships for technical laboratory equipment, including procurement, installation oversight, service level agreements, and technical issue resolution
- Strong troubleshooting and diagnostic skills: ability to identify and resolve issues in test hardware, sensing, data acquisition, and environmental control systems
More about this role
Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost Silicon-dominant batteries have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Coreshell's Si anode material is lower than the cost of graphite and utilizes the largest abundant critical mineral supply in the US and Europe. We strive to transform the global energy and transportation market by enabling cost effective and secure domestic battery supply.
