Battery Test Engineer



Quality Assurance
San Leandro, CA, USA
Posted on Thursday, November 9, 2023

Cuberg, a cutting-edge battery technology company, is seeking a highly motivated Battery Test Engineer to join our team. In this role, you will be responsible for developing and executing tests to ensure the quality, performance and reliability of our battery products. You will work cross-functionally with our R&D team to understand product requirements, design test plans, and execute tests to provide clear and actionable data.
As a Battery Test Engineer, you should have some experience with battery cycler scripting and a strong working knowledge equipment deployment and commissioning process. In addition, you should have a strong background in battery testing and a solid understanding of battery systems.

Cuberg builds high-performance energy solutions based on next-generation technology for the world’s most demanding battery applications. Cuberg technology, paired with the manufacturing excellence of parent company Northvolt, will help give rise to a new generation of mobility businesses and decarbonize hard-to-abate segments of the transportation industry.
Cuberg technology uses a lithium metal anode and proprietary liquid electrolyte to simultaneously solve the interlocking challenges of battery performance and manufacturability. While incumbent battery technologies, such as lithium-ion, can be too heavy and low-performing for use in aircraft, Cuberg’s battery cells are lightweight and high-performance. The technology is also compatible with industry standard manufacturing methods, enabling scalability, reliability and traceability across the value chain.
Cuberg and Northvolt believe that complete electrification will require a revolutionary spirit and a practical mind. We won’t just design the world’s best batteries—we will ship them at scale.
