Mechanical Maintenance Technician

ABOUT US tozero is Europe’s leading deep-tech startup in lithium-ion battery recycling, driving decarbonization and the circular economy through innovative material recovery solutions. We are on a mission to recover critical materials from end-of-life batteries and build a cleaner, more sustainable future. WHAT WE'RE LOOKING FOR As a Mechanical Technician, you will be the technical backbone of our recycling plant’s physical infrastructure. Mechanical Maintenance Installation & Assembly: Independently install, assemble, and commission a wide range of industrial equipment, machinery units, and complex piping systems. Modifications & Upgrades: Execute technical modifications and plant improvements to optimize process performance and equipment integration. Equipment Maintenance: Maintain, align, and troubleshoot pumps, motors, gearboxes, valves, and heavy process equipment. Spare Parts Management: Identify, replace, and manage critical spare parts to ensure rapid recovery and minimal downtime. Preventive Care: Execute and optimize preventive and corrective maintenance schedules across all mechanical assets. Fabrication: Perform welding, machining, and metal fabrication as required for repairs or bespoke plant adjustments. Diagnostic Excellence: Diagnose mechanical wear and tear, implementing sustainable technical solutions to extend equipment life. Integrated Technical Support General Maintenance: Develop and actively execute preventive maintenance plans from scratch to improve equipment reliability. Safety & Compliance: Ensure strict compliance with safety standards, specifically Lockout-Tagout (LOTO) and heavy machinery protocols. Workshop Ownership: Maintain clear technical documentation and contribute to the organization and efficiency of the maintenance workshop. Minor Electrical Support: Perform basic, non-complex electrical tasks incidental to mechanical work (e.g., safely disconnecting/reconnecting motors during a mechanical swap or replacing simple sensors) to maintain workflow momentum. Plant Operations and Production Support Operational Support: Operate recycling equipment during commissioning and daily production. Material Handling: Manage loading, unloading, and feeding process lines to ensure continuous flow. Site Stewardship: Support plant ramp-up and maintain high 5S/safety standards. This role is for a true hands-on professional with deep expertise in mechanical systems, rotating equipment, and industrial fabrication, capable of working independently in a demanding industrial environment. You will work directly on the shop floor, performing installations, maintenance, troubleshooting, and supporting production during ramp-up and scale-up phases. In this role, you will play a key part in ensuring plant reliability, uptime, and safe operations. While your primary focus is mechanical excellence, you are a versatile team player ready to jump into plant operations and material handling to keep the facility running at peak performance. REQUIRED QUALIFICATIONS Completed vocational training as an Industrial Mechanic (Industriemechaniker) or equivalent trade.
