Other Engineering
San Leandro, CA, USA
Posted on Friday, April 28, 2023

The R&D Engineer will push forward the design and development of advanced lithium metal batteries by integrating component-level innovation into a full cell chemistry ready for scale-up. The R&D Engineer will develop research plans, perform experiments, analyze data, and present results. They will collaborate closely with other engineers and scientists at Cuberg, as well as external partners, to improve Cuberg’s lithium-metal battery technology. In this role, the Engineer will assist with technical projects in assessing cell performance, safety, reliability, and manufacturability. The ideal candidate has demonstrated aptitude for systems-level problem-solving and strives to grow these skills further. We work cross-functionally and collaboratively to serve our collective mission to build a better, more sustainable world from our new state of the art San Leandro facility. By joining Cuberg’s Advanced R&D Team, you will be a key player in maturing our cell chemistry, contributing to electrifying the aviation industry, and being a part of the transition to a greener future.

Join us in building the future of energy.


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.
