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. Because this role sits at the critical junction between manufacturing and electrochemical testing, you will also take on key data responsibilities: ensuring that test data is accurately captured, traceable, and structured for downstream analysis by the data science and cell engineering teams. The ideal candidate has hands-on experience managing battery test labs at scale, a meticulous approach to calibration and data integrity, and the ability to keep a growing test infrastructure running reliably in a fast-paced development environment.
Core Responsibilities:
  • Own the installation, commissioning, calibration, maintenance, and continuous improvement of battery test infrastructure, including cyclers, environmental chambers, incubators, and other analytical and electrochemical characterization equipment, ensuring high uptime and reliable operation.
  • Serve as the primary point of contact for test equipment vendors: managing procurement, service contracts, updates, and technical support.
  • Develop and maintain calibration and preventive maintenance programs for all testing equipment.
  • Design, build, and validate experimental test setups such as instrumented cell fixtures or specialized electrochemical test apparatus.
  • Develop and maintain standardized test protocols for cell formation, characterization, aging, reliability, and qualification, collaborating closely with cell engineers, manufacturing, and data science teams.
  • Manage test data integrity and traceability by ensuring accurate data capture, metadata tagging, database integration, and alignment between manufacturing records and electrochemical test results.
  • Lead troubleshooting and root-cause investigations of test hardware, sensors, environmental controls, data acquisition systems, and measurement anomalies to improve test accuracy, reproducibility, and operational efficiency.
  • Support investigations of cell performance and quality variation, identifying and differentiating true cell-related issues from testing, equipment, instrumentation, or data-system anomalies.
  • Support the definition and implementation of data schemas, naming conventions, and quality checks for battery test data, working with the database engineering team to ensure clean, structured, and ML-ready datasets.
  • Manage the flow of test data from equipment to database systems, ensuring data completeness, proper metadata tagging (cell IDs, batch numbers, manufacturing lot traceability), and timely availability for analysis. Serve as the primary link between manufacturing records and electrochemical test results.
  • Collaborate cross-functionally with Cell Development, R&D, Manufacturing, and Quality teams to ensure testing infrastructure and workflows meet evolving development needs.
