Job Description:

Your Work Shapes the World at Caterpillar Inc.

When you join Caterpillar yourejoining 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 dontjust 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.

Role Overview:

Mechanical Structural Engineer responsible for design analysis and product realization of battery systems and power electronics for energy and power applications. The role focuses on ensuring structural integrity electrical packaging compliance vibration robustness and manufacturable designs under defined loading conditions thermal environments and boundary constraints.

Key Responsibilities:

Structural Design & Analysis: -

Define load cases and boundary conditions based on vibration inputs shock events G loads and operating conditions - Perform linear and nonlinear FEA: static modal random vibration (PSD) fatigue thermo mechanical and drop impact analysis

- Evaluate handling scenarios including lifting and transportation loads as per standards

- Design sheet metal Casting and Extrusion based structures

- Execute weld design considering fatigue strength HAZ effects and distortion

- Perform bolted joint analysis (preload clamp retention fatigue sealing compres

sion)

- Develop isolation mount (iso-mount) models for vibration isolation and res

onance control

- Incorporate thermal solutions including Coolant pipes HV

-LV harnessing and auxiliary systems in the design keeping serviceability in mind

Packaging & Electrical Integration: -

Develop 3D packaging layouts considering space claim clearances and serviceability - Define creepage and clearance distances for high

-voltage systems in compliance with applicable standards

- Ensure compliance with electrical insulation dielectric spacing and safety

requirements (IEC/UL/ISO) - Incorporate EMI/EMC considerations sealing (IP ratings) and thermal paths in packaging

Work with electrical teams with intermediate-level exposure to harness design including routing constraints bend radii connector interfaces and protection requirements

- Optimize packaging for thermal dissipation and structural support Design

Definition & Controls:

- Apply GD&T (ASME Y14.5) and perform tolerance stack-up analysis

- Select materials based on mechanical thermal electrical insulation and corro

sion properties (e.g. Galvanic corrosion).

Manufacturing Integration:

- Implement DFM/DFA for manufacturability and assembly robustness and process selection (sheet metal forming welding casting molding)

- Address variation distortion and residual stress - Support DV/PV builds and CAE correlation

Quality & Product Development:

- Execute DFMEA/PFMEA with structured risk mitigation

- Drive APQP deliverables across development phases

- Manage PPAP requirement

Supplier Technical Engagement:

- Evaluate supplier capability in part quality fabrication welding and dimensional control

- Validate tooling and process capability

- Lead technical reviews and issue resolution

Failure Analysis & Optimization:

- Perform root cause analysis (stress correlation fracture test vs CAE)

- Correlate strain vibration and thermal data with simulation

- Optimize designs for fatigue life stiffness efficiency and cost

Required Qualifications: -

Bachelors/master is in mechanical aerospace engineering or similar

- more than 3 to 6years experience in battery systems power electronics or energy & power applications Caterpillar: Confidential Green -Experience with Teamcenter PLM for product data management BOM management and design release processes

Additional information: This job required 5days working from office.
