Key Responsibilities

Tooling Design & Development

• Design and engineer patterns, tooling, coreboxes, flasks, matchplates, and fixtures for Lost Foam and green sand molding processes.
• Develop gating, riser, venting, and pattern layouts to meet metallurgical, dimensional, and surface finish requirements.
• Specify tooling materials, coatings, and construction methods appropriate for production volume, process capability, and foundry environment.
• Support additive-manufactured tooling, hybrid tooling, and traditional pattern construction methods.

Manufacturing & Process Support

• Collaborate with foundry operations to ensure tooling is manufacturable, maintainable, and optimized for production throughput.
• Support tooling tryouts, first-article runs, and production launch activities.
• Troubleshoot tooling-related casting defects such as misruns, porosity, erosion, burn-in, mold shift, and dimensional non-conformance.
• Lead tooling modifications and continuous improvement initiatives to improve yield, scrap, and cycle time.

Engineering Analysis & Documentation

• Create and maintain tooling drawings, BOMs, specifications, and change documentation.
• Participate in DFMEA/PFMEA activities related to tooling and molding processes.
• Support simulation activities (e.g., mold fill/solidification analysis) to validate tooling concepts prior to build.
• Ensure tooling designs comply with internal standards, customer requirements, and applicable industry specifications.

Cross-Functional Collaboration

• Work closely with Product Engineering, Quality, Manufacturing, Maintenance, and external tooling suppliers.
• Support cost-reduction and value-engineering initiatives related to tooling design and reuse.
• Provide technical guidance to pattern shops and external vendors during tool fabrication.

Required Qualifications

• Proven experience in foundry tooling, pattern design, or molding processes supporting Lost Foam and/or green sand molding operations.
• Practical working knowledge of pattern construction, gating and risering, mold design, and tooling functionality in a production foundry environment.
• Ability to interpret and apply engineering drawings, specifications, and GD&T.
• Experience using 3D CAD software (Creo, SolidWorks, NX, or similar) for tooling and pattern design.
• Strong understanding of casting fundamentals including metal flow, solidification, shrinkage, and defect prevention.
• Demonstrated ability to troubleshoot tooling-related casting issues on the foundry floor.
• Effective communication skills and ability to work cross-functionally with manufacturing, quality, and suppliers.

Preferred / Bonus Qualifications

• Bachelor’s degree in mechanical engineering, Manufacturing Engineering, Metallurgical Engineering, or a related field.
• Experience with additive manufacturing for tooling or patterns.
• Familiarity with casting simulation tools (e.g., MAGMA, ProCAST, FLOW-3D).
• Experience supporting high-volume production foundries or automated molding lines.
• Knowledge of tooling cost estimating and supplier management.
• Hands-on experience with tooling tryouts and shop-floor troubleshooting.

Key Skills & Competencies

• Strong problem-solving and root-cause analysis skills
• Practical, manufacturing-focused engineering mindset
• Effective communication with both technical and non-technical teams
• Ability to manage multiple tooling projects simultaneously
• Continuous improvement and cost-reduction orientation

Work Environment

• Combination of office, pattern shop, and foundry floor environment
• Requires occasional lifting, PPE usage, and exposure to heat, dust, and industrial equipment
• Travel to suppliers or other manufacturing locations as needed
