Do you want to join a rockstar team of innovators and make a real, measurable impact on the future of sustainability? 

At Circu Li-ion, we are building the technologies that power the circular economy. Through our automated disassembly solutions, we unlock the value hidden in Li-ion batteries, EV components, and other complex products that contain critical raw materials. This is urban mining designed to scale. 

What makes us different is not just what we build—but why we build it. By enabling the reuse of cells, modules, and other high-value components, we reduce waste, cut emissions, and keep valuable materials in use for longer. 

If you’re excited about solving complex engineering challenges, working in a fast-growing deep-tech environment, and contributing to a more sustainable future, Circu Li-ion is the place where your work truly matters.
