Full Time Technician Sheldon, IA, US

Position Summary

The Mechanical Engineer I supports the design, development, and continuous improvement of Maintainer's service truck bodies and related products. Working under the guidance of senior engineering staff, this position is applies sound mechanical engineering principles to create and maintain 3D models, engineering drawings, bills of materials, and product documentation. Mechanical Engineer I collaborates with Manufacturing, Purchasing, Sales, Quality, and Supply Chain to develop products that are safe, manufacturable, cost-effective, and meet customer requirements.

This role utilizes modern 3D CAD modeling, design automation, and engineering systems to improve engineering efficiency, product quality, and manufacturing processes.

• Design and develop mechanical components, assemblies, and complete vehicle body systems using 3D CAD software.
• Create, revise, and maintain engineering drawings, bills of materials (BOMs), engineering change documentation, and product specifications.
• 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, Solid Works, 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.
