We are the Corporate Engineering and Product Development organization within JB Poindexter & Co., supporting nine business units across the company’s portfolio of commercial vehicle and upfit solutions spanning Class 1-7 vehicles. The team develops and launches innovative products and technologies across a diverse range of applications and end markets.

We operate in a highly dynamic, project-based environment, managing programs ranging from rapid design and prototype cycles to complex multi-year product launches, while partnering closely with business units, customers, suppliers, manufacturing teams, and purchasing.

We are seeking a hands-on Mechanical Designer with 3-5 years of experience to join our Corporate Engineering team. This role is intended for an engineer who is strong in mechanical design and CAD and can take product concepts from requirements through detailed design, prototype build, validation, and design release.

The position will focus on commercial vehicle bodies, mechanical systems, fabricated components, and custom product-development projects across multiple JBPCO business units. The ideal candidate combines Solid Works-based design capability with practical knowledge of GD&T, tolerance analysis, design for manufacturability, BOM/change control, prototype support, testing, and engineering problem-solving.

Mechanical Design & CAD

• Develop 3D CAD models and assemblies for commercial vehicle bodies, mechanical systems, fabricated metal and plastic components, brackets, enclosures, mounting structures, and related product hardware.
• Create and release detailed 2D engineering drawings using proper dimensioning practices and GD&T.
• Perform tolerance stack-up analysis and evaluate fit, function, assembly variation, and interface requirements.
• Apply sound mechanical design principles to improve strength, durability, serviceability, manufacturability, and cost.
• Support CAD standardization across business units, including Solid Works templates, settings, metadata, drawing practices, and shared design methods.
• Work within Solid Works PDM or similar product-data-management environments to maintain controlled CAD and drawing records.
• Develop product documentation including drawings, engineering BOMs, control drawings, build documentation, and other design-release deliverables.
• Create and maintain engineering Bills of Materials and support engineering change-control activities.
• Support concept development, design reviews, prototype design, design release, and handoff to manufacturing.
• Assist with DFMEA, DVP&R, gate-review deliverables, requirements tracking, and other activities within a formal product-development process.
• Support value engineering and product cost-reduction activities while maintaining performance and quality requirements.
• Work closely with prototype, fabrication, manufacturing, and purchasing teams to ensure designs are practical to build and assemble.
• Provide design-for-manufacturability and design-for-assembly guidance for sheet metal, machined parts, molded plastics, castings, welded structures, and other relevant manufacturing processes.
• Participate in hands-on prototype builds, fit checks, design debugging, dimensional reviews, and validation activities.
• Use 3D printing and other rapid-prototyping methods for concept evaluation, fixtures, and low-volume components when appropriate.
• Collaborate with suppliers on feasibility reviews, manufacturability, tooling considerations, cost, quality, and design improvements.

• Support mechanical and structural analysis, including…
