Energy Jobline ZR; Milwaukee (WI); On-site; USD 90,000 - 110,000; Full time

Job summary

Energy Jobline ZR in the Greater Milwaukee Area is seeking an experienced Injection Mold Design & Project Engineer to lead custom mold projects from concept through T1 sampling and handover. You will design in SolidWorks and manage timelines, costs, and cross-functional collaboration.

The role requires 3–7 years of hands-on mold design, expertise in SolidWorks, and strong knowledge of molding processes, tooling, and project execution.

Qualifications

• 3–7 years of hands-on injection mold design experience.
• Expert proficiency in SolidWorks for 3D mold design and 2D drafting.
• Experience driving tooling projects from concept to press sampling (T1) and validation.
• Deep understanding of machining processes, mold steel selection, and polymer behavior (shrinkage, rheology, design-for-molding).
• Hands-on skills with mold tryouts, press sampling, press troubleshooting, and mold builds.

Responsibilities

• Full Tool Design: Translate part models and product requirements into complete, production-ready 2D/3D mold designs in SolidWorks (core/cavity, gating, runners, hot/cold manifolds, cooling, ejection, slides/lifters, venting).
• Manufacturability & Analysis: Conduct parting line development, draft analysis, shrinkage/warpage allowances, steel-safe strategies, DFM/DFMEA, and Moldflow/pre-simulation reviews to optimize gate placement, filling, and cooling.
• Component Selection & Specs: Select mold bases, materials/steels (H13, P20, S7, stainless), standard components, surface finishes, and tight tolerances.
• Documentation: Generate comprehensive 2D detailing, component drawings, and BOMs for machining, EDM, and assembly. Manage ECOs and revision history.
• End-to-End Ownership: Lead tooling projects from kick-off through design reviews, T1 sampling, toolroom/supplier release, and final validation.
• Schedule & Budget Control: Define project scope, track milestones, manage budgets, identify risks, and mitigate accordingly to ensure on-time delivery.
• Cross-Functional Collaboration: Partner with internal tooling, CNC machining, EDM, and press operators, as well as external suppliers.
• Continuous Improvement: Document design standards, refine design libraries/templates, and capture lessons learned to drive process efficiencies.
