About The Position

We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy. By leveraging innovative materials, advanced manufacturing techniques, and next-generation energy storage architectures, we are building the future of sustainable energy. Can’t find the company name? It’s not you, it’s us! We’re really excited about the potential of our technology, product, and mission, and have chosen to remain in stealth mode. If the job description piques your interest, please apply. If your skillset is aligned with what we’re looking for, the team will reach out to schedule your interview and tell you a bit more about us (e.g. who we are). Role We are seeking a hands-on Engineering Technician to support the assembly, testing, and development of next-generation battery cells. This role will work closely with engineers and scientists to build prototype and pilot-scale cells, execute manufacturing processes, collect data, and help scale production from development into commercialization. Unlike large-scale automated manufacturing environments, this position involves significant manual assembly, process experimentation, and problem-solving. The ideal candidate enjoys working with their hands, follows detailed procedures, and is excited about contributing to the growth of a rapidly evolving battery technology company.
