About Us

Avanti Battery Company is a battery storage startup commercializing a new battery chemistry recently discovered at MIT. Officially launched in 2022, our aim is to develop a battery chemistry and a long‑duration storage product that will enhance the integration of renewable energy and enable a 100% decarbonized electricity grid. We are seeking experienced battery engineers, research scientists, technicians, and lab professionals who are excited to shape the foundational technologies of tomorrow’s electricity grid.

We have supportive investors and a clear runway to design, test, innovate, and create. The founders of Avanti are inventors and entrepreneurs with extensive experience at successful climate tech and battery startups. We offer generous compensation and benefits because we truly believe that the best way to develop technology is to assemble and support a team of dedicated professionals who are passionate about the scientific process of discovery and who enjoy working on challenging problems every day.
