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
