About Cat (CaterpillarCareers)

• Engineering 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.

Responsibilities

• Apply strong structural design, engineering mechanics, and simulation-driven engineering principles to develop robust, manufacturable, and cost-effective battery module solutions for Caterpillar applications.
• Collaborate with Caterpillar machine and application teams to finalize customer requirements, operating conditions, mechanical interfaces, packaging constraints, and validation requirements.
• Develop battery module architecture, packaging, and detailed mechanical designs, including cell-retention and compression systems, structural components, mounting features, busbar supports, insulation components, cold plates, and overall module cooling solutions.
• Integrate Cell Monitoring Units (CMUs), sensing components, electrical interconnects, busbars, and high-voltage and low-voltage harness interfaces into the module mechanical architecture.
• Account for cell dimensional variation, swelling, compression, thermal expansion, electrical clearance and creepage, assembly requirements, and serviceability throughout the design.
• Develop production-ready 3D models, assemblies, BOMs, material specifications, and mechanical interface requirements.
• GD&T and perform tolerance stack-up and packaging analyses.
• Select materials, mechanical joints, insulation systems, thermal-interface materials, sealing solutions, and manufacturing processes.
• Perform structural, thermal, and thermo-mechanical simulations.
• Correlate simulation results with physical test data.
• Lead Design of Experiments (DoE).
• Support DFM, DFA, DFMEA, DVP& R and validation activities.
• Resolve design, validation, supplier, and manufacturing issues.

Requirements

• Qualifications Bachelor's or Master's degree in Mechanical Engineering or related discipline.
• Minimum three years of relevant experience in battery modules, battery packs, energy storage systems, power electronics, or electromechanical product development.
• Strong fundamentals in structural design, engineering mechanics, strength of materials, mechanical joints, material selection , tolerances, heat transfer, and manufacturing processes.
• Demonstrated experience developing mechanical products from concept through production release.
• Strong capability in 3D modelling, assembly design, mechanical packaging, and component integration.
• Hands-on experience with structural, thermal, or thermo-mechanical simulation.
• Working knowledge of battery module architecture, cooling systems, insulation, electrical isolation, clearance and creepage, and electromechanical integration.
• Familiarity with GD&T, tolerance analysis, DFM, DFA, DFMEA, DVP&R, PPAP, PLM, and engineering change processes.
• Experience with cooling manifold design, coolant routing, sealing interfaces, or HV/LV harness design is preferred.
• Strong technical problem-solving, engineering judgment, documentation, collaboration, and communication skills.
