The Energy Storage Test Engineer will execute charging/refueling tests to assess the performance of software and hardware components at the vehicle level using public or private infrastructure. The role involves analyzing test data, comparing it to charging standards and expected performance, and performing refueling/recharging infrastructure site performance evaluations, including interoperability, communication vehicle-infrastructure, and refueling/recharging rates. The engineer will also monitor and maintain state and nationwide infrastructure performance metrics, research infrastructure performance issues, and recommend corrective actions. Additionally, the engineer will develop and maintain testing standards, procedures, and specifications, ensuring proper documentation and communication of test results. Participation in industry refueling/recharging standard development for commercial vehicles and collaboration with universities, national labs, and external research bodies on advanced technology projects are also key responsibilities. The engineer will write reports and present to company leadership about energy storage systems and refueling infrastructure technical roadmaps, including analysis approaches and test results from internal and external sources.
