CNC Programmer/Machinist

Job Title: CNC Programmer / Machinist

Location: Middleton, TN | Onsite

Overview

The CNC Programmer / Machinist supports machine-shop production by editing and troubleshooting manually written G-code for CNC mills, lathes, and vertical turret lathes (VTLs). This hands-on role works alongside operators on setups, work offsets, tooling, and program issues, with a focus on adapting existing programs and workholding to keep production moving.

The schedule is Monday–Friday, eight hours per day, on first shift. Production starts at 6 a.m.; start-time flexibility is available up to 7:30 a.m.

Key Responsibilities

• Edit and troubleshoot existing G-code and create new programs by modifying existing programs for mills, lathes, and VTLs.
• Help operators set up machines, adjust work offsets, and resolve machine alarms, tooling issues, and program errors in real time.
• Use and adapt existing fixtures, workholding, and custom jigs to minimize setup time and improve production.
• Interpret blueprints, identify drawing or model discrepancies, and provide feedback to engineering.
• Verify first-piece inspections using micrometers, calipers, height gauges, and bore gauges.
• Research unfamiliar controller functions and existing programs independently, and serve as the primary contact for the shop area when needed.
• Support program prove-outs, including running machines when able and an operator is unavailable.
• Develop CAM programs as production priorities allow, choosing an approach that supports a timely production response.

Required Qualifications

• Machinist background with experience editing existing manual G-code on CNC mills, lathes, and VTLs.
• Ability to create new programs by copying and modifying existing programs.
• Hands-on experience with machine setups, work offsets, and existing fixtures and workholding.
• Experience with multiple CNC controllers and the ability to research unfamiliar functions. Equipment uses controllers such as Fanuc, Mitsubishi, Okuma, and Giddings & Lewis; experience with every listed controller is not required.
• Ability to interpret blueprints, identify drawing or model errors, and use precision measuring tools for first-piece inspection.
• Strong communication and troubleshooting skills, with the ability to work alongside operators and respond to changing production needs.

Preferred Qualifications

• SolidCAM experience for mills and lathes, or proficiency with other CAM software.
• Four-axis milling and live-tooling experience.
• Ability to run machines independently to prove programs when operators are unavailable.
