Join a Legacy of Precision Moldmaking Excellence
We're partnered with one of the Midwest’s longest-standing and most respected plastic moldmaking companies—now in its fourth generation of family ownership and over 125 years strong. With a full in-house operation handling everything from mold design to sampling, they are expanding their engineering team to meet rising demand for custom-built plastic injection molds.
This is a chance to step into a high-impact design role where your experience with multi-cavity molds, hot runner systems, and complex mold actions will be put to immediate use in a fast-paced, supportive, and tight-knit manufacturing environment.
What You’ll Be Doing:
Design plastic injection molds from concept through final release using SolidWorks and/or Unigraphics (NX)
Create 3D models and 2D drawings of complete mold assemblies, ensuring correct:
Parting lines and shut-offs
Lifters, slides, cores, and cooling layouts
Mold flow and DFM considerations
Translate customer part data into mold-ready designs
Collaborate directly with toolmakers, engineers, and CNC programmers to ensure feasibility
Update engineering change orders, support mold sampling, and provide post-build updates
Work independently and own your projects from start to finish
You’re a Great Fit If You Have:
Must-Haves:
3–5+ years of experience in plastic injection mold design
Proficiency in SolidWorks and/or Siemens NX (Unigraphics)
Deep understanding of mold components, including hot runners, lifters, slides, and shutoffs
Experience with complex tooling designs and multi-cavity molds
Nice-to-Haves:
Associate's or bachelor’s in engineering or plastics technology
Familiarity with mold flow analysis and DFM
Experience working in full-service mold shops
Strong collaboration skills and ability to work in a plug-and-play role without close supervision
Why This Role Rocks:
Join a stable, 4th-generation family-owned company
Be a key player in a small but technically elite team
Long-term growth potential with likely full-time conversion
Modern, well-equipped 45,000 sq ft shop with full in-house capabilities
Work on high-quality, custom molds used in diverse industries
Benefits Upon Conversion:
Full medical, dental, and vision insurance
401(k) with company match
