Find & Apply For CNC Operator Jobs in Greenville, South Carolina

Amsted Rail has an opening for a CNC Specialist. The CNC Specialist will create, optimize, and run CNC programs using Mastercam for horizontal machining centers (HMCs), vertical machining centers (VMCs), and CNC turning centers in a hands-on production environment. Perform efficient machine setups, prove-outs, first-article runs, and in-process adjustments to achieve safety, quality, and productivity targets. Provide hands-on machine operation support across shifts and coach operators on best practices. Drive cycle-time reduction, optimize tool life, and promote "quality at the source" across assigned machining equipment. Maintain compliance with company safety, environmental, and personal growth standards. Foster a collaborative work environment and communicate effectively with employees at all levels of the organization. Safety, 5S & Continuous Improvement

• Follow and enforce PPE, guarding, and Lock‑Out/Tag‑Out (LOTO) requirements on all machining assets.
• Identify and correct unsafe machine conditions; escalate guarding or interlock concerns.
• Lead or participate in 5S events for machining cells; sustain visual standards.
• Track and improve OEE drivers: availability, performance, and quality where data is available. CNC Programming & Optimization
• Generate, import, and post CNC programs (MasterCam or equivalent) for HMC, VMC, and turning centers.
• Edit G- & M‑code at the control to resolve issues, optimize feeds/speeds, correct toolpaths, and improve surface finish.
• Perform cycle‑time studies; recommend and implement reductions through toolpath changes, canned cycles, high‑efficiency strategies, and SMED changeover methods.
• Standardize program naming, revision control, and document control practices.
• Coordinate with Engineering on new part introductions and design‑for‑manufacturability feedback. Machine Setup & Operation (HMC / VMC / Turning)
• Perform full setups: workholding, tooling, touch‑off, offsets, probing (if equipped), coolant and program load.
• Run first article; verify features to print, adjust tool wear and work offsets, and update control notes.
• Operate machines in production mode; monitor tool wear, chip evacuation, and repeatability across lots.
• Support quick changeovers between part numbers; apply SMED principles to reduce spindle downtime.
• Troubleshoot alarms, tool breakage, chatter, and dimensional drift; escalate when needed.
• Specify cutting tools, holders, extensions, and pull studs appropriate to material, reach, and tolerance requirements.
• Inspect and prep raw material, fixture alignments, and reference datums prior to machining.
• Support preventative maintenance (PM) and Total Productive Maintenance (TPM) tasks on assigned machine groups. Quality & Documentation
• Perform in‑process and final inspection using precision measuring instruments (calipers, micrometers, bore ga.
