Mechanical Engineer, Production Development

Company & Position Overview:

J.B. Poindexter & Co., Inc. (JBPCO) is a privately held, diversified manufacturing company forecasting over $2.5B in annual revenues and employing over 8,000 team members. The six operating subsidiaries, covering 60 locations, are engaged in the production of commercial truck bodies, step-vans, utility trucks, ambulances, electric and alternative fuel vehicles, and expandable foam plastic packaging. For more information, visit https://www.jbpoindexter.com.

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. This team leads the development and launch of innovative products and technologies across a diverse set of applications and end markets.

We operate in a highly dynamic, project-based environment, managing programs ranging from rapid development cycles (weeks) to complex, multi-year product launches, while partnering closely with business units, customers, and suppliers to bring fresh solutions to market.

We are seeking a versatile and hands-on Mechanical Engineer with 2-4 years of experience to join our Corporate Engineering team. You will serve as an internal centralized engineering resource supporting multiple businesses across our organization, working on a wide range of product development projects. While the primary focus is commercial truck bodies, you will also support one-off accessory designs and custom engineering requests for testing and manufacturing-ideal for an engineer who enjoys variety and is not locked into a narrow specialty.

This role blends design, analysis, prototyping, manufacturing support, supplier interaction, and customer engagement. We are looking for a well-rounded engineer who thrives in both CAD and hands-on shop environments.

Essential Duties and Responsibilities:

Product Development & Design

• Lead and contribute to the design of commercial truck bodies and related mechanical systems.
• Support custom accessories, retrofit, and specialty engineering projects across multiple business units.
• Develop 3D models and engineering drawings using SolidWorks.
• Apply GD&T, tolerance stack-up analysis, and proper documentation practices.

Engineering Analysis

• Perform structural and mechanical simulations (i.e., FEA).
• Evaluate designs for durability in heavy-duty, high-vibration, and high-load environments.
• Use sound engineering principles to ensure reliability, manufacturability, and safety.
• Competitive benchmarking activities, reverse engineering, VAVE

Manufacturing, Prototyping & 3D Printing

• Work closely with in-house prototype and fabrication teams to ensure manufacturable designs.
• Provide DFM guidance for production processes and manufacturing lines.
• Participate in hands-on prototype builds, fit checks, and validation activities.
• Utilize 3D printing for prototyping, concept evaluation, fixtures, or low-volume components.
• Incorporate additive manufacturing constraints and capabilities into design work when applicable.

Cross-Functional Collaboration

• Collaborate with mechanical engineers, designers, fabricators, and cross functional teams.
• Serve as an internal centralized engineering resource to multiple business units, supporting diverse project needs.
• Communicate directly with customers to gather requirements, present designs, and provide technical insights.
• Work with suppliers on feasibility reviews, design improvements, and manufacturing considerations.

Project Leadership & Mentoring

• Lead engineering projects from concept through design release and handoff.
• Support multi-disciplinary project teams as a key contributor.
• Train, mentor, and guide interns, new engineers, and junior technical staff.

Qualifications and Skills:

• Bachelor's degree in Mechanical Engineering or related field.
• 2-4 years of experience in mechanical engineering, preferably in automotive or commercial vehicle industries.
• Proficiency in SolidWorks.
• Strong understanding of:
• o GD&T
• o Tolerance analysis
• o Product lifecycle
• o DFMEA / PFMEA
• o DFM
• o DVP&R
• Familiarity with automotive and commercial truck standards (SAE, ISO, FMVSS).
• Ability to manage multiple projects simultaneously.
• Hands-on prototyping and experience with 3D printing technologies.

Preferred Qualifications:

• Experience with body design
• Background working with heavy-duty or fleet vehicle environments.
• Experience using COMSOL or similar FEA tools.
• Practical fabrication, machining, or shop-floor experience.
• Control systems understanding
• Experience with Microsoft Suite of tools
• Strong communication skills for customer and cross-functional interactions.
• Comfort working in an engineering team with diverse project scopes.

What We Are Looking For:

• A broad, adaptable problem solver—not overly specialized.
• Someone who enjoys a mix of CAD, analysis, prototyping, and hands-on engineering.
• A team-oriented engineer who can lead when necessary and support others when needed.
• A self starter who thrives working on varied projects in a dynamic environment.
