• Prepare electrodes through slurry mixing, coating, drying, punching, pressing, calendering, and related steps
• Assemble cells in glovebox or dry-room environments
• Run electrochemical test protocols including formation, cycling, rate testing, and other standard evaluations
• Maintain accurate records of build parameters, material lots, test conditions, and results
• Identify and troubleshoot common cell‑build and test issues
• Maintain and help qualify lab equipment such as mixers, coaters, balances, crimpers, cyclers, and glove boxes
• Work closely with materials and process teams to evaluate new anodes, formulations, and cell designs
• Support SOP development and continuous improvement of battery workflows
• Follow strict safety and contamination‑control practices

• BS in materials science, chemistry, chemical engineering, mechanical engineering, or related field
