• Interpret engineering drawings, GD&T, and specifications to create accurate and efficient machining processes
• Select tooling, workholding, and machining strategies to support optimal cycle times and part quality
• Support new product introduction (NPI) by developing and validating initial machining processes

Setup & Prove-Out

• Perform complete machine setups including tooling, fixturing, offsets, and program verification
• Run and validate first‑piece parts to ensure conformance to specifications
• Troubleshoot and resolve issues related to setup, tooling, programs, and machine performance
• Establish stable, repeatable setups and clear instructions for operators

Production Support & Continuous Improvement

• Collaborate with machinists, operators, and cross‑functional teams to ensure efficient production flow
• Monitor and improve cycle times, tool life, and overall process efficiency
• Maintain and update CNC programs, setup sheets, and work instructions

• Identify and implement process improvements including tooling, fixturing, and programming enhancements

Quality & Compliance

• Ensure all parts meet quality standards and customer requirements, including GD&T specifications
• Validate part quality through inspection processes and documentation (e.g., first article, in‑process checks)
• Maintain compliance with all safety, quality, and operational procedures
• Support 5S and overall shop organization standards

Requirements

• Minimum of five (5) years of combined CNC programming and setup experience (mills and/or lathes)
• Strong proficiency with CAM software (Mastercam, NX, or similar)
• Experience with multi-axis machining (3, 4, and/or 5-axis)
• Strong understanding of GD&T, blueprint reading, and machining mathematics
• Proven ability to perform full machine setups and prove‑out new jobs
• Experience working with tight‑tolerance components, preferably in aerospace or similar industries
• Strong problem‑solving skills and attention to detail
• Ability to work collaboratively in a fast‑paced manufacturing environment
• Strong work ethic and commitment to quality and continuous improvement

Preferred Qualifications

• Experience with exotic materials (e.g., titanium, tungsten)
• Experience with high‑mix / low‑volume production environments
• Familiarity with multiple machine platforms (Haas, Mazak, DMG Mori, Okuma, etc.)
