• Utilize CAD automation tools, parametric modeling techniques, and engineering design standards to improve design accuracy, consistency, and efficiency.
• Support manufacturing by applying Design for Manufacturing and Assembly (DFM/DFA) principles to improve quality, reduce cost, and simplify production.
• Collaborate with Manufacturing, Purchasing, Sales, Quality, and Supply Chain to resolve design, production, and customer-related issues.
• Assist with new product development and continuous improvement initiatives by evaluating existing products and recommending design enhancements.
• Develop, coordinate, and document product validation testing, including test plans, procedures, and reports.
• Participate in troubleshooting product performance, manufacturing concerns, and field issues using structured problem-solving methods.
• Research new materials, manufacturing processes, and technologies for application in future products.
• Support engineering change management by maintaining accurate product structures, engineering documentation, and part numbering.
• Participate in cross-functional product review meetings and production readiness activities, including inspection and evaluation of completed vehicles.
• Work with suppliers to evaluate purchased components, manufacturing capabilities, and technical requirements.
• Follow all company safety policies, engineering standards, quality system requirements, and departmental procedures.
• Perform other duties as assigned.

Required Qualifications

• Bachelor’s degree in mechanical engineering or related engineering discipline from an accredited institution.
• Demonstrated mechanical aptitude and the ability to apply engineering principles through academic coursework, senior design projects, internships, co-op experiences, or other hands-on technical activities.

• Ability to read and create engineering drawings in accordance with ASME drafting standards.
• Strong written and verbal communication skills.
• Ability to manage multiple projects and priorities in a collaborative environment.

Preferred Qualifications

• Internship, co-op, or project experience in manufacturing, product development, or mechanical design.
• Experience with Creo, SolidWorks, Inventor, or comparable 3D CAD software. Our current design software is Creo.
• Experience with CAD automation tools, parametric modeling, family tables, design tables, or configurable product design, including using parameters to drive automation of models and drawings.
• Familiarity with Product Data Management (PDM), Product Lifecycle Management (PLM), or ERP/MRP systems.
• Exposure to finite element analysis (FEA) or engineering simulation.
• Knowledge of welding, sheet metal fabrication, machining, hydraulic systems, electrical systems, and vehicle structures.

Technical Skills

The successful candidate should have working knowledge of:

• 3D CAD modeling and detailed drawing creation
• Engineering change management
• Bills of Materials (BOM) development
• Design validation and testing
• Microsoft Office Suite
• Engineering documentation and technical report writing
