battery pack mechanical design.

• Lead the overall structural design of power battery packs, including module layout, enclosure strength analysis, lightweight design, and thermal management system integration, ensuring high safety, cost efficiency, and manufacturability (DFM).  
• Responsible for product full life cycle management from concept design to mass production, define technical requirements, 3D model design and 2D drawing release, prepare and participate in design reviews.
• Analyze the impact of sheet metal, stamping, injection molding, and die-casting processes on battery pack structures, optimizing manufacturing workflows to reduce costs and improve efficiency.  
• Resolve complex technical issues during prototyping and mass production (e.g., welding deformation, sealing failures), propose process improvements, and guide tooling design for suppliers.  
• Lead finite element analysis (FEA) for battery packs, covering structural strength, vibration, impact, and thermodynamics simulations to ensure compliance with safety standards (e.g., UN38.3, GB/T 31467).   Collaborate with testing teams to develop validation plans, verifying pack reliability under extreme conditions (e.g., thermal cycling, salt spray tests).  
• Act as the technical core, coordinating with electrical, thermal management, and BMS teams for system integration, and deliver documentation (BOM, DFMEA). Support post-sales technical issue resolution.  
• Lead industry-leading technologies investigation (CTP/CTC technology, thermal runaway protection, lightweight design, cost optimization) and implement the solutions on  battery design.

skills and experience required.

• Bachelor's degree or above in Mechanical/Mechatronics/Materials/Electrical Engineering, or related fields. Master's degree is preferred.
• Over 8 years of experience in battery pack/module design with prismatic or blade cell, familiar with key components such as cells, busbar, FPC, cooling plate, etc..
• Deep knowledge of cell characteristics (e.g., NCM, LFP), pack technologies (e.g., CTP/CTC), and industry trends (e.g., solid-state battery integration).  
• Complete battery pack development project experience, familiar with the process from design to mass production (e.g., V-model development).
• Proficient in battery pack system design tools (e.g., CATIA/CAD/ANSYS) and simulation analysis (CAE/CFD).
• Familiar with battery industry standards and testing specifications.
• Strong data analysis and statistical skills, attention to detail, and good record-keeping and reporting abilities.
• Strong communication and project management skills.
• Good written and verbal English skills.
