Position Summary
We're looking for a Mechanical/Product Development Engineer who enjoys turning ideas into real products. In this role, you'll take ownership of new product designs from concept through production, developing 3D CAD models, creating detailed drawings, building and testing prototypes, and working closely with manufacturing to bring designs to life.
You'll work on a diverse range of commercial and defense products, giving you the opportunity to solve different engineering challenges rather than focusing on the same product or process every day.
This is a hands-on engineering role for someone who enjoys designing, building, testing, improving, and ultimately seeing their work become a finished product.
What You'll Do
- Develop new mechanical products and components from initial concept through production
- Create 3D CAD models, assemblies, and detailed engineering drawings
- Evaluate and improve existing products through redesign and engineering analysis
- Develop prototypes and support product testing, qualification, and validation
- Apply Design for Manufacturing (DFM) principles to new and existing designs
- Identify critical-to-function features and develop practical solutions for quality, reliability, and manufacturability
- Work directly with manufacturing, machinists, technicians, and other engineers to bring designs into production
- Support material, component, tooling, and manufacturing process selection
- Create and process Engineering Change Orders (ECOs)
- Apply GD&T and sound engineering principles to ensure designs meet functional and manufacturing requirements
- Participate in product development reviews and help move projects from concept to production
What We're Looking For
Required:
- B.S. in Mechanical Engineering or a related engineering field
- Minimum of a 3.3 GPA for all completed degrees
- Professional experience with mechanical/product design and development
- Experience using 3D CAD software to create models and engineering drawings
- Understanding of Design for Manufacturing (DFM)
- Experience taking products or components from design into production
- U.S. Citizenship required due to ITAR requirements
Preferred:
- 3+ years of mechanical/product development engineering experience
- Experience with GD&T / ASME Y14.5
- Experience with CNC machining, sheet metal, injection molding, casting, tube fabrication, or other manufacturing processes
- Experience with product development or stage-gate processes
- Experience with prototyping and product testing
- Experience processing Engineering Change Orders (ECOs)
Why This Role?
- Work on both commercial and defense products
- Take ownership of projects from concept through production
- See your designs become real, production-ready products
- Work alongside experienced engineers, machinists, technicians, and manufacturing professionals
- Gain exposure to a wide range of design and manufacturing technologies
- Solve new engineering challenges across a diverse product portfolio
