Senior Mechanical Engineer

Senior Mechanical Engineer Location: Rho, Italy (near the metro station) Contract Type: Full-time, On-site Working Hours: 09:00–12:45, 14:00–18:00 Compensation: Commensurate with experience Role Description We are seeking a Senior Mechanical Engineer to play a critical role in the mechanical design and development of battery stacks and containerized systems. This position is intended for an experienced professional who will act as a technical reference for mechanical architecture, integration, and robustness of stack modules and container-level systems. The role sits at a key interface between detailed component development and overall system design. The Senior Mechanical Engineer will work closely with a mechanical development engineer, the Head of Product (focused on system-level container design), and the hydraulic engineer, ensuring coherent integration of mechanical structures, piping interfaces, thermal and hydraulic constraints, and manufacturability considerations. The position combines hands-on mechanical design, engineering judgment, and cross-functional coordination, supporting the transition from laboratory and pilot-scale systems to industrialized containerized solutions. Responsibilities Lead the mechanical design and development of battery stacks, stack frames, manifolds, and structural components Define and oversee the mechanical architecture of stack modules within containerized systems Collaborate closely with the hydraulic engineer to ensure proper integration of piping, flow paths, sealing concepts, and pressure constraints Interface with the Head of Product on container-level system design, layout, integration, and scalability Supervise and technically guide the work of a mechanical development engineer Perform mechanical analyses related to structural integrity, tolerances, thermal expansion, vibration, and assembly Support design for manufacturing (DFM), design for assembly (DFA), and serviceability considerations Contribute to the definition of mechanical standards, design guidelines, and best practices Support prototype build, testing, and troubleshooting activities, including root-cause analysis of mechanical issues Prepare technical documentation, CAD data packages, and internal design reports Contribute to technology roadmap and product development decisions from a mechanical engineering perspective Qualifications MSc or PhD in Mechanical Engineering 6 years of experience in mechanical design and development of complex engineered systems (liquid pressurized systems, or similar) Strong experience in mechanical design of assemblies, structures, and interfaces (preferably in fluid-based systems) Proficiency with CAD tools and mechanical design methodologies Experience working in multidisciplinary R&D teams Strong problem-solving skills and engineering judgment Ability to balance hands-on design work with system-level thinking Excellent written and verbal communication skills in English
