Job Description

This Mechanical Design Engineer role leads the end-to-end development of heavy-duty truck accessories and systems for commercial and vocational truck platforms. You will focus on mechanical design, integration, and validation of complex accessory products, including hydraulic systems, structural components, and electrical integration. Working as a key member of a fast-paced product design team, you will deliver innovative, durable, and high-performance solutions tailored to demanding customer applications and industry requirements.

Responsibilities

• Lead the mechanical 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 for commercial and vocational truck platforms.
• 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 and demanding service conditions.
• Develop and optimize hydraulic systems, including pump and motor selection, hydraulic circuit design, and performance tuning to meet functional and durability targets.
• Ensure seamless electrical integration of powered accessories with truck OEM or aftermarket power and control systems, coordinating closely with electrical and controls engineers.
• Create and maintain complete engineering documentation, including 3D models, detailed drawings, bills of materials (BOMs), engineering change orders, and test reports.
• Support and participate in validation testing, including environmental, fatigue, load, and field testing, and use test results to refine and improve designs.
• Evaluate test data and engineering feedback to determine whether designs meet functional and performance specifications, and prepare design modifications as needed.
• Troubleshoot and resolve design-related issues that arise in manufacturing and production assembly, working closely with production teams to implement effective solutions.
• Engage directly with suppliers and customers to define requirements, clarify specifications, resolve technical challenges, and ensure product compatibility with truck platforms and accessory systems.
• Drive continuous improvement initiatives to enhance product performance, durability, cost-effectiveness, and manufacturability.
• Maintain thorough, accurate, and consistent documentation practices and ensure that engineering records are organized and up to date.

Skills & Qualifications

• 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) to support structural design and validation.
• Experience developing 3D designs in Creo is a strong plus; exposure to SolidWorks 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 and organized approach to work, with the ability to manage multiple projects and priorities within a product design team.

Preferred Qualifications

• Experience designing heavy duty truck mounting assemblies
• Experience doing 3d designs in Creo
