Tozero is Europe's leading deep-tech startup specializing in the recycling of lithium-ion batteries. Committed to accelerating decarbonization and transforming the material life cycle, we’re actively crafting sustainable recycling solutions for a cleaner and more innovative future. This role combines maintenance engineering, spare parts management, CMMS administration and hands-on support in our production facility. The successful candidate will work closely with both the engineering team in Munich and the operations team in Gendorf to improve equipment reliability and maintenance processes. Reporting to the Maintenance department lead, the successful candidate will work closely with the Head of operations, Maintenance mechanical engineer, and external equipment suppliers to support reliable day-to-day plant operation and continuous improvement initiatives 1. Operational coordination & spare parts logistics Inventory & supplier management: Identification of critical spare parts, inventory optimization to minimize downtime, and direct communication with equipment manufacturers for parts procurement and technical support. Equipment standardization: Analyzing and unifying components (e.g., pumps and seals) to reduce spare parts inventory levels and enable faster maintenance interventions. 2. CMMS & technical documentation CMMS (computerized maintenance management system) management: Entering new equipment, updating the database according to field conditions, and tracking preventive maintenance records (full training on our CMMS system will be provided). Technical archiving: Maintaining technical manuals, CE certifications, intervention reports, and tracking contracts with external service providers and inspectors. 3. Hands-on support & Gendorf operations Field work (Gendorf ~ 2 days per week): On-site presence to monitor ongoing operations and act as a direct liaison with management in Munich. Assistance to mechanical engineer: Hands-on assistance during the servicing and installation of mechanical subsystems (pumps, piping, gearboxes, mixers, filter presses, heat exchangers). 4. Process improvement & SOPs (standard operating procedures) Equipment reliability: Data-driven failure analysis (transitioning from subjective assessment to component lifespan analysis). SOP & design for maintenance: Creating and reviewing standard operating procedures and participating in the early stages of new system development to ensure future maintainability.
