Job description

Job Description

We are seeking a highly reliable, detail-driven CNC Programmer who can independently program, set up, operate, and maintain CNC equipment in a production manufacturing environment. This role requires strong technical judgement, consistency, and accountability. The CNC Programmer is responsible not only for creating efficient programs, but also for ensuring parts are produced correctly, safely, on time, and to specification—every time.

This is a hands‑on role. Candidates who prefer desk‑only programming or require close supervision will not be a good fit.

CNC Programmer Responsibilities

Programming & Setup

• Read, interpret, and verify technical blueprints, GD&T, and 3D models before machining begins.
• Design and develop machining fixtures required to meet quality, safety, and cycle‑time goals.
• Create, modify, and optimize CNC programs (Fusion 360, Mastercam) for accuracy, repeatability, and efficiency.
• Develop programs that work correctly with defined setups and fixtures—no trial‑and‑error programming.
• Select, load, and verify correct cutting tools, offsets, and work coordinates prior to running parts.

Machine Operation

• Load raw materials correctly and safely into CNC machines.
• Set and verify machine parameters to meet part specifications.
• Run first‑article parts and verify dimensions before full production.
• Monitor machines during operation and make necessary adjustments to maintain quality.

Quality Control

• Perform in‑process and final inspections using appropriate measuring tools.
• Ensure all parts meet print specifications and internal quality standards.
• Identify non‑conforming parts immediately and take corrective action.

Troubleshooting & Maintenance

• Diagnose and resolve machining, tooling, and program issues with minimal downtime.
• Perform routine machine cleaning, maintenance, and basic repairs as required.
• Escalate major equipment or quality issues promptly and accurately.

Production Support

• Assist with production work, secondary operations, and deburring as required.
• Maintain an organized, clean, and safe work area.
• Train new employees on machine operation, safety procedures, and basic program understanding.

CNC Programmer Requirements

• High school diploma or GED.
• Previous work experience as a CNC programmer/Machine Operator.
• Ability to read and interpret design blueprints.
• Extensive experience with computer modeling software (Fusion 360, Mastercam).
• Strong attention to detail.
• Ability to work independently and stick to a deadline.
• Ability to stand for extended periods.
• Ability to lift heavy objects.
• Ability to work after‑hours when required.
