CNC Machinist

About the role

The CNC Machinist is responsible for setup, operation, and basic programming adjustments on CNC milling and/or turning centers to produce precision components to print specifications. This role requires attention to detail, comfort working in a high-mix/low-volume environment, and the ability to maintain tight tolerances on critical features.

Responsibilities

• Set up and operate CNC mills and/or lathes including vertical, horizontal, and multi-axis machines.
• Interpret blueprints, GD&T, and work instructions to determine machining requirements.
• Verify dimensions using micrometers, calipers, height gages, bore gages, and other precision instruments.
• Maintain tight tolerances (often within ±0.0001″ depending on component).
• Make tooling, offsets, and program adjustments using G and M codes as required.
• Run existing CNC programs with the ability to make minor edits for efficiency or dimensional accuracy.
• Machine a variety of metals (tool steels, stainless steels, aluminum, etc.) and non-metal materials as required.
• Work within a job-shop scheduling environment: high mix, low volume, short runs.
• Inspect parts during and after machining to ensure quality standards and print compliance.
• Maintain a safe, clean, and organized work area.
• Collaborate with engineering, tooling, and grinding departments as needed.

Requirements

High school diploma or equivalent. Journeyman, trade school, or formal apprenticeship a plus but not required.

Skills

• 3+ years of CNC machining experience.
• Vertical and/or horizontal machining experience (4th and 5th axis a plus).
• Familiarity with CAD/CAM software (e.g., MasterCAM, SolidWorks, Fusion 360) is a plus.
• Experience machining tight-tolerance components for high-precision assemblies.
• Grinding experience (surface, OD/ID, or jig) is preferred.
• Ability to interpret and modify G and M code.
• Comfortable running programs written by others.

Physical Requirements

• Ability to stand for extended periods.
• Frequent bending, stooping, and reaching.
• Ability to lift heavy materials as required in a manufacturing environment.

Benefits

• Comprehensive medical and dental programs.
• Life insurance.
• Generous paid time off program.
• Retirement savings plan with company match.
• No waiting period for benefits—eligible on your first day of employment.
