Cuberg is seeking a highly skilled and motivated Supplier Quality Engineer (SQE) to join our team. The Supplier Quality Engineer will ensure the lithium metal cell components procured from external suppliers meets the highest standards of quality, safety, and compliance.

Ideal candidates are detail-oriented, proactive problem-solvers with a strong technical and business background. The SQE must be comfortable in a fast-paced, highly collaborative, and dynamic startup environment, with the ability to work well with internal and external stakeholders, as well as independently.

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.
