What You Will Do
Lead new tooling and mold initiatives: manage quotes, DFM, concept/tool approvals, Moldflow CAE validation, and supplier coordination (remote and on-site) through tool qualifications.
Own end-to-end mold development: define qualification criteria, develop and verify scientific molding processes, and drive launch readiness into operations.
Optimize process parameters using cavity-pressure data and statistical methods (DOE); correlate CAE and measured part/process data to ensure robust, repeatable production windows.
Manage project execution and documentation: track schedule, status, budget, and milestones; ensure complete, version-controlled records (estimates, CAE results, tooling plans, QC reports).
Provide technical support and troubleshooting for equipment, tooling, and process issues; lead corrective actions with operations and suppliers, and transfer lessons learned across teams to drive continuous improvement.
Drive measurable improvements in tooling cost, cycle time, scrap reduction, and on-time mold delivery against defined KPI targets.
Collaborate with global manufacturing plants to ensure successful mold transitions and alignment with receiving site expectations.
Who You Are (Basic Qualifications)
Experience in injection molding, mold development, and tooling.
Background in scientific molding principles with hands-on experience on molding machines and ancillary equipment.
Experience in tooling systems and design for manufacturability (hot-runner, cooling/ejection, venting, mold materials) and preventative strategies to minimize adjustments and scrap.
Proven troubleshooting and problem-solving ability to diagnose molding/tooling issues and drive improvements in quality, cost, and lead time.
Experience with CAD/3-D modeling, basic CAE flow analysis, and familiarity with GD&T for reviewing product prints.
Demonstrated end-to-end project ownership: define qualification criteria, drive launch readiness, and manage schedule, budget, and milestones
What Will Put You Ahead
Bachelor's degree in Mechanical, Materials, Chemical, Plastics Engineering, or related discipline.
Six Sigma Green Belt (or higher) or equivalent structured problem-solving training.
RJG Master Molder I/II, AIM, or equivalent scientific-molding certification with hands-on expertise in cavity-pressure control, setting process windows, data acquisition, and transfer of best-practice settings.
Experience with insert molding and overmolding processes, particularly for automotive connector or electronic component applications.
Practical experience with new tooling launches, supplier coordination, and on-site tool qualifications for transportation/automotive components.
Proficient with CAE simulation tools (Moldflow, Moldex3D, Sigmasoft) and able to correlate simulation results with measured part and process data.
Strong systems and CAD skills: ERP/PLM (SAP, Windchill/Teamcenter or similar), advanced Excel (pivot tables, formulas, VBA), and 3-D CAD (NX preferred).
Experience working in a global, fast-paced manufacturing environment with shifting priorities.
