Job Duties and Responsibilities:

• Create and maintain detailed 3D models, assemblies, drawings, bills of materials, and design documentation for injection molds, mold components, fixtures, and related tooling.
• Develop tooling concepts that address part geometry, resin characteristics, shrink, gating, venting, cooling, ejection, manufacturability, cycle time, quality, serviceability, and expected tool life.
• Lead and support design-for-manufacturability reviews with customers and cross-functional teams; identify technical risks and recommend practical solutions early in the development process.
• Review customer models, prints, specifications, tolerances, and revision requirements to ensure tooling designs align with intended product and process requirements.
• Collaborate with toolmakers, machinists, process engineers, and external tool shops to ensure designs can be manufactured, assembled, sampled, maintained, and repaired effectively.
• Support mold-flow analysis, tolerance analysis, stack-up reviews, material selection, and tooling standards as appropriate to the program.
• Participate in tool design reviews, project meetings, mold trials, troubleshooting, qualification activities, and production-readiness reviews.
• Evaluate existing molds and recommend design changes to improve part quality, cycle time, reliability, cavitation, uptime, and ease of maintenance.
• Manage design changes and technical records in accordance with document-control, configuration-management, customer, quality-system, and regulatory requirements.
• Provide accurate technical inputs for quotations, schedules, capital requests, and supplier decisions.
• Support root-cause investigations and corrective actions related to tooling performance or molded-part quality.
• Contribute to standard work, design libraries, lessons learned, and continuous-improvement efforts across the molding organization.
• Perform other duties and support strategic projects as assigned.

Qualifications:

Education

• Associate degree in Mechanical Design, Tool Design, Engineering Technology, or a related field required; bachelor's degree preferred.
• Equivalent combination of education, apprenticeship, and directly related experience may be considered.

Experience

• Five or more years of injection-mold or precision-tooling design experience preferred.
• Experience designing complex, multi-cavity, hot-runner, insert-molding, overmolding, or high-precision tooling strongly preferred.
• Experience in medical device, regulated manufacturing, or contract manufacturing preferred.

Knowledge, Skills & Abilities

• Advanced proficiency with 3D CAD and detailed drawing practices; SolidWorks or comparable software experience preferred.
• Strong knowledge of injection-mold construction, machining methods, tool steels, polymers, GD&T, tolerance analysis, and DFM principles.
• Ability to read and interpret technical drawings, specifications, and customer requirements.
• Practical problem-solving, organization, and communication skills with the ability to manage multiple priorities.
• Ability to collaborate effectively with customers, suppliers, engineering, quality, operations, and hands-on technical teams.
