Full Stack Engineer

YOUR MISSION

Do you want to join our rockstar team of innovators and make a REAL impact in the sustainability space?

Circu Li-ion is driving the green revolution by prolonging the lifespan of individual battery cells through our cutting-edge automated battery disassembly lines. Our systems disassemble Li-ion battery packs into reusable Li-ion cells, minimizing waste and maximizing sustainability. Our mission is to bring cost of re-using material down and enable true urban mining with robotics and smart software. The cheaper disassembly is, the closer we get to a real circular economy.
