Mechanical Design Engineer

Job Description

This Mechanical Design Engineer will lead the end-to-end development of heavy‑duty accessories and systems for commercial and vocational truck platforms, focusing on mechanical design, integration, and validation of complex accessory products including hydraulic systems, structural components, and electrical integration.

• Lead design and integration of heavy accessory products such as liftgates, tool storage systems, service bodies, utility cranes, winches, PTO‑driven systems, and other chassis‑mounted equipment.
• Collaborate cross‑functionally with electrical, controls, hydraulics, and manufacturing teams to develop fully integrated accessory solutions.
• Own the full product development lifecycle from concept through production launch, including prototyping, CAD design, FEA, design for manufacturability (DFM), and validation testing.
• Design robust mechanical structures and assemblies using steel, aluminum, and composite materials suitable for heavy‑duty environments.

• Ensure seamless electrical integration of powered accessories with truck OEM or aftermarket power and control systems.
• Create and maintain complete engineering documentation, including 3D models, detailed drawings, BOMs, change orders, and test reports.
• Support and participate in validation testing (environmental, fatigue, load, field) and use test results to refine designs.
• Evaluate test data and engineering feedback to determine whether designs meet specifications and prepare design modifications.
• Troubleshoot and resolve design‑related issues that arise in manufacturing and production assembly.
• Engage suppliers and customers to define requirements, clarify specifications, resolve technical challenges, and ensure product compatibility.
• Drive continuous improvement initiatives to enhance product performance, durability, cost‑effectiveness, and manufacturability.
• Maintain thorough, accurate, and consistent documentation practices.

• Bachelor’s degree in Mechanical Engineering (highly preferred).
• 8+ years of professional engineering experience in mechanical design and product development.
• Experience with finite element analysis (FEA) for structural design and validation.
• Experience developing 3D designs in Creo (strong plus); exposure to Solid Works is beneficial.
• Experience with hydraulic system design, including pump and motor selection, circuit design, and performance optimization.
• Familiarity with integrating mechanical systems with electrical and control systems on truck platforms.
• Disciplined, organized, and able to manage multiple projects and priorities.
