ABOUT US tozero is building Europe’s next critical raw materials champion. We recycle lithium-ion batteries at industrial scale and recover lithium and graphite more efficiently than mining, enabling Europe’s energy transition and independence. We are scaling from pilot to a first-of-a-kind industrial demonstration plant. This phase requires clarity, discipline, and strong operating systems across the company. WHAT WE'RE LOOKING FOR As tozero grows, execution complexity increases faster than headcount. The CEO cannot remain the operating system of the company. This role exists to build and run the company’s operating system. It ensures that priorities turn into execution, KPIs are visible and acted upon, and people processes scale without chaos. The role sits in the CEO Office as a senior operator with clear authority over execution systems and operational cadence. Your mission is to ensure that tozero scales with clarity, speed, and reliability by owning the systems that run the company. This includes execution tracking, KPI visibility, people operations, and follow-ups, allowing the CEO and leadership team to focus on strategy, fundraising, and external impact.
