Job description

CNC Programmer/Operator - Vertical Milling Center (HAAS, VF3 & VF9)

Salary Range: $30.00 - $40.00 / hour (Commensurate with experience)

Job Description

We are seeking an experienced and detail-oriented CNC Programmer/Operator specializing in a Vertical Milling Center to join our precision machining team. In this role, you will serve as a core technical resource, responsible for programming, setting up, and optimizing CNC vertical mills.

The ideal candidate possesses advanced mastery of HAAS controls and machinery, a strong background in CAM (such as Mastercam), and AutoCAD software, and the ability to maintain tight tolerances for high-precision components.

Key Responsibilities

• Programming & Optimization: Create, modify, and optimize 2.5 to 3-axis CNC programs for Vertical Machining Centers (VMCs) using CAD/CAM software to maximize efficiency.
• Machine Setup & Operation: Perform complex daily machine setups, including tool selection, work holding configuration, fixture adjustments, and verifying machine offsets.
• Precision Machining: Machine diverse metals and alloys (such as tool steel, stainless steel, and aluminum) while holding strict tolerances down to ±0.001″.
• Quality Assurance: Conduct first-piece and in-process quality inspections using standard precision measuring tools (micrometers, calipers, bore gauges, indicators).
• Troubleshooting: Diagnose and resolve software, programming errors, G-code/M-code anomalies, and tooling issues directly on the shop floor.
• Collaboration: Partner with manufacturing engineers, quality control teams, and floor machinists to streamline production cycles and minimize downtime.

Qualifications & Experience

Required:

• Experience: Minimum of 3-5+ years of practical CNC programming and setup experience in a precision machine shop or production environment.
• Equipment Expertise: Hands-on expertise programming and setting up HAAS CNC Vertical Mills.
• Technical Skills: Proficient with CAM software (Mastercam preferred) and manual editing of G-code and M-code.
• Metrology: Strong competence using precision inspection tools.
• Physical Demand: Ability to stand for long periods and lift up to 50 lbs. safely.

Preferred:

• Experience working in high-mix, short-run prototype environments as well as long-term production runs.
