About the company

Northvolt makes green batteries for a blue planet. Affordable cells and high-quality battery systems. All manufactured with a record-low carbon footprint. Purposely built to provide Europe with the opportunity to switch to renewable energy – efficiently and entirely.

To accomplish this, we do things differently. We design, manufacture, and recycle everything under one roof. We even build our own factories. All this is incredibly challenging and requires us to think in unconventional ways. We’re constantly experimenting, learning and adapting to make batteries so great – they will one day make oil history.

Northvolt is growing fast. We’re staffing our international office in Stockholm, our R&D facility, Northvolt Labs, in Västerås, as well as our Gdansk facility for production of battery systems. We're also hiring for our gigafactory Northvolt Ett in Skellefteå, Sweden. We want to work with smart individuals from all disciplines. Strong individuals that truly want to make a positive impact on the future. Those of us already on board share a passion for our mission. We’re prepared to work hard in pursuit of excellence. We enjoy the ride and our main drive is to make a difference for real. As a team, we’re dedicated to thinking new, working hard and having fun.
