Career Area:

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.

We are looking for an experienced Mechanical Systems Engineer to lead the design development and integration of mechanical systems for Power Conversion & Distribution systems in electrified platforms.

This role focuses on system architecture enclosure design thermal-mechanical integration and mechanical component design (DFM/DFA) with a strong emphasis on compact lightweight and high power-density design philosophy.

You will work closely with electrical thermal and manufacturing teams to deliver robust manufacturable and optimized mechanical solutions for demanding environments such as automotive and industrial applications.

Key Responsibilities

• Define mechanical system architecture for power conversion and distribution systems translating requirements into subsystem and component-level designs
• Lead design and development of enclosures housings and structural components for power electronic systems (inverters converters Battery Power distribution units)
• Drive compact and lightweight design strategies optimizing packaging for space weight thermal performance and structural integrity
• Own mechanical design for manufacturability and assembly (DFM/DFA) ensuring cost-effective and scalable production
• Perform material selection (metals polymers composites) considering thermal mechanical environmental and cost constraints
• Ensure robust sealing ingress protection (IP ratings) and environmental durability for harsh operating conditions
• Collaborate with electrical and PCB teams for mechanical-electrical integration ensuring proper clearances mounting and cable routing
• Conduct and guide FEA analysis (structural thermal vibration) to validate design robustness and reliability
• Support prototype builds testing and validation including root cause analysis and design improvements

Technical Skills

• Mechanical system architecture and product integration
• Enclosure and housing design for power electronics
• Compact packaging and lightweight design optimization
• DFM/DFA principles for high-volume manufacturing
• Thermal management (heat sinks cooling strategies interface materials)
• Material science (aluminum plastics coatings composites)
• Structural and vibration design for harsh environments
• Sealing gasketing and IP-rated enclosure design
• Tolerance stack-up and GD&T
• Cross-domain integration (mechanical electrical systems)

Tools and Software

• CAD: Creo SolidWorks CATIA NX
• Simulation: ANSYS Abaqus (structural & thermal FEA Good to have)
• Thermal Analysis Tools: Icepak Flotherm (Good to have)
• PLM Tools: Windchill Teamcenter

Soft Skills and Teamwork

• Strong system-level thinking with attention to detail
• Ability to work collaboratively across electrical thermal and manufacturing domains
• Effective communication and design review capability
• Problem-solving mindset with focus on practical manufacturable solutions
• Ownership from concept through production

Qualifications

• Bachelors or Masters degree in Mechanical Engineering with 8 to 15 years of experience
• Experience in power electronics electrification automotive or industrial systems preferred
• Proven experience in compact lightweight enclosure design for high-power systems
