Senior Engineer, Battery Test Engineering

Duties

• Develop and execute battery test plans using Arbin scheduler to simulate real-world usage scenarios and evaluate performance under varying conditions.
• Collaborate with modeling and algorithm teams to define test objectives that support data-driven model development and validation.
• Design and assemble custom battery test setups for different cell formats and chemistries, ensuring compatibility with lab infrastructure.
• Configure and calibrate lab equipment, including battery cyclers, environmental chambers, and safety systems, to enable accurate and safe testing.
• Create and maintain standardized test protocols (e.g., HPPC, GITT, drive cycles) to ensure consistency and repeatability across experiments.
• Automate test execution and data logging using Arbin MITS Pro and Python scripts to improve efficiency and reduce manual intervention.
• Analyze large datasets using Python, MATLAB, or Excel to extract key battery metrics such as capacity fade, internal resistance, and efficiency.
• Integrate and validate new lab equipment with software systems, including development of custom drivers and APIs for control and data acquisition.
• Apply battery modeling knowledge to interpret test results, extract model parameters, and support algorithm refinement.
• Communicate findings and insights through technical reports and regular syncs with cross-functional teams to guide development and decision-making.
