Job Description:

Your Work Shapes the World at Caterpillar Inc.

When you join Caterpillar, you're joining a global team who cares not just about the work we do – but also about each other. We are the makers, problem solvers, and future world builders who are creating stronger, more sustainable communities. We don't just talk about progress and innovation here – we make it happen, with our customers, where we work and live. Together, we are building a better world, so we can all enjoy living in it.

Job Responsibilities:

• 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 CAT battery design.

Job Requirements:

• 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, enjoys teamwork, interested in new technologies, and self-motivated.
• Experience in leading new energy vehicle companies or top battery companies is preferred.
