- Working knowledge of AutoCAD.
- Excellent understanding of GD&T (Geometric Dimensioning & Tolerancing), blueprint interpretation, and tolerance stack-up analysis.
- Experience using Coordinate Measuring Machines (CMM), Zoller tool presetters, and other precision measurement equipment.
- Strong knowledge of carbide tooling, inserts, tool holders, and machining best practices.
- Experience designing or working with hydraulic and pneumatic fixtures and workholding systems.
- Solid understanding of Statistical Process Control (SPC), process capability studies, and manufacturing quality systems.
- Demonstrated hands-on troubleshooting skills in a production machining environment.
Preferred Qualifications
- Experience in high-volume automotive manufacturing.
- Knowledge of multi-axis CNC machining.
- Experience with ERP and Manufacturing Execution Systems (MES).
- Lean Manufacturing and/or Six Sigma Certification.
