- Career Area: 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
- 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
- we work and live. Together, we are building a better world, so we can all enjoy living in it. Job Description Mechanical Design Engineer – E+ES (Battery and Power Systems) Role Overview Mechanical Design Engineer responsible for concept-to-release mechanical design and product realization of battery systems and power electronics for energy and power applications. The role focuses on robust packaging, structural integrity, manufacturable designs
- compliance with electrical safety and environmental requirements, working closely with cross-functional teams through structured design reviews and NPI gateways. Key Responsibilities Concept Development & Engineering Solutions:
- Develop and compare concepts (architecture, packaging, mounting strategy, service access) and translate requirements into feasible engineering solutions.
- Generate layout options and trade studies (mass, cost, manufacturability, serviceability, thermal paths, sealing/IP, safety).
- Drive design decisions with clear rationale, assumptions, and risk/mitigation plans. Mechanical Design & Packaging:
- Create 3D CAD models for sheet metal, castings, extrusions, brackets, enclosures, and interfaces supporting batteries and power electronics.
- Develop 3D packaging layouts considering space claim, clearances, creep/clearance for HV, assembly sequence, and serviceability.
- Integrate cooling hardware (coolant pipes/plates), HV–LV harness routing provisions, protection features, and auxiliary components within the mechanical package.
- Select materials and isolations considering strength, thermal performance, electrical insulation interfaces, corrosion (including galvanic), and environmental exposure. Design Definition, Controls & Release:
- Apply GD&T (ASME Y14.5) and perform tolerance stack-ups for critical interfaces and sealing features.
- Develop and maintain BOMs, part numbers, and design releases using Teamcenter PLM.
- Define interface control documents (ICDs) and support configuration management across development phases. Design Verification and support:
- Define load cases and boundary conditions for defined operating, handling, transport, and mounting scenarios.
- Perform medium to high fidelity simulations to support design decisions.
- Support test planning, instrumentation correlation (strain/vibration/thermal), and issue resolution based on test findings.
- Support resolving field issues by proposing and validating ICA and PCA Manufacturing & Build Support:
- Implement DFM/DFA and process selection (sheet metal forming, welding, casting, molding) to ensure manufacturability and assembly robustness.
- Address variation, distortion, residual stress, and dimensional control with suppliers and internal manufacturing teams.
- Support DV/PV builds, prototype iterations, and lessons-learned incorporation into subsequent releases. Design Reviews, Quality & Risk Management:
- Plan and execute structured design reviews (Concept/Architecture, Preliminary Design Review, Critical Design Review, drawing/design release reviews) with clear action tracking.
- Execute DFMEA/PFMEA and drive risk mitigation, validation evidence, and closure of open items.
- Drive APQP deliverables and support PPAP documentation as required. Supplier Technical Engagement:
- Evaluate supplier capability for fabrication, welding, dimensional control, and quality; validate tooling and process capability.
- Lead technical discussions, drawing clarifications, and issue resolution to meet cost, quality, and schedule targets. Required Qualifications:
- Bachelor’s/Master’s in Mechanical/Aerospace Engineering or similar.
- 3+ years of experience in mechanical design for battery systems, power electronics, or energy & power applications.
- Proficiency with 3D CAD and drawing practices; experience with Teamcenter PLM for product data management and release processes.
- Working knowledge of HV packaging constraints (clearance/creepage), sealing/IP
- integration of thermal and harness routing provisions. Additional Information: This job required 5days working from office.
