Senior Design Engineer – Mechanical / Electrical

Load & Haul Products | Caterpillar Resource Industries

Location: Decatur, IL - Mossville, IL (AC) (In office 5 days a week)

Travel: Up to 10%

Relocation Assistance: Available

Visa Sponsorship: Not Offered

Caterpillar Inc. is the world’s leading manufacturer of construction and mining equipment. You will have the opportunity to join the Load and Haul Electrical Installation team, responsible for mechanically integrating electrical solutions across Large Wheel Loaders, Compactors, Wheel Tractor Scrapers, Underground Vehicles, and Articulated Trucks.

About the Role

As a Senior Design Engineer, you will lead electrical installation projects with a strong mechanical focus, ensuring electrical systems are effectively packaged, protected, and integrated within complex application environments. You’ll work across the full product lifecycle—from early concept through production—collaborating closely with mechanical, electrical system, manufacturing, and supplier teams.

This role is ideal for Mechanical Engineers with experience in vehicle systems, structures, packaging, routing, and integration, as well as Electrical Engineers who enjoy working at the intersection of both disciplines.

Why This Role Stands Out

• End-to-end ownership: Influence design decisions from concept through validation and production, including mechanical packaging and electrical integration tradeoffs.

• True cross-functional collaboration: Work alongside mechanical design, electrical systems, manufacturing, suppliers, and purchasing to optimize performance, quality, durability, and cost.

• Complex product systems: Apply your engineering expertise to large, highly integrated off-highway machines operating in demanding environments.

• Growth & impact: Strengthen leadership skills while delivering high-value solutions to customers across diverse applications and platforms.

What You Will Do

• Lead the mechanical design and integration of electrical systems within complex vehicle platforms, ensuring robust routing, protection, and packaging.

• Design and develop components, brackets, harness routing paths, enclosures, and installation schemes that balance electrical performance with mechanical durability.

• Own cost, quality, validation, and schedule for assigned projects.

• Collaborate with suppliers to ensure manufacturability, serviceability, and lifecycle efficiency.

• Partner with manufacturing teams to address assembly feasibility, tolerance stack-up, and installation repeatability.

• Assist supply specialists and buyers with supplier development and performance improvement.

• Drive collaboration across product development, value chain, manufacturing, commercial, and product support organizations.

• Research and develop new technologies related to vehicle integration, packaging, thermal considerations, and durability.

• Develop and document functional and installation design requirements, including mechanical constraints and environmental considerations.

• Lead and participate in design reviews, ensuring conformance to electrical and mechanical design standards and best practices.

• Organize, coordinate, and execute prototype builds, testing, and analysis, including fit, form, function, and durability assessments.

Top Candidates Will Have

• Experience with Large Wheel Loaders, Wheel Tractor Scrapers, heavy equipment, or mining applications.

• Background in mechanical engineering, electrical engineering, or integrated systems design.

• Hands-on experienc
