Arbetsbeskrivning

Join Rivus Batteries on our mission to develop the world’s most sustainable battery chemistry. We’re a growing startup developing organic electrolytes for flow batteries, and we’re looking for a laboratory engineer to help us accelerate the transition to sustainable, large-scale energy storage. This is a key role for someone who is experienced in practical organic flow battery testing. You’ll be joining a tight-knit team focused on progress and real-world deployment.

About Rivus

Rivus Batteries is a Swedish startup developing aqueous organic flow battery electrolytes to deliver stationary energy storage at lower cost and climate footprint than today’s battery systems. Our electrolytes are based on widely available elements – we believe this is crucial for sustainably covering the growing global demand for energy storage capacity.

Following years of academic research, we’re now in our third year of commercialization – with R&D and scaling up at the heart of everything we do. We are relentlessly working on optimizing our electrolyte formulation, collaborating with chemical suppliers to scale up production, and preparing for customer pilot installations.

We are a mission-driven tech startup, committed to holistic care for the environment and corporate responsibility on all levels.
