CNC Machinist I

A.W. Chesterton Company • Groveland, MA

4d • Onsite

About The Position

The CNC Machinist I (also described as NC Operator I) is a frontline manufacturing role operating numerical control machine tools—including lathes and millers, and potentially EDM machines—to manufacture metal or plastic components. The role may involve running more than one machine at a time in a cellular manufacturing environment. The operator inspects work, performs quality checks against engineering drawings, and records statistical process control (SPC) data manually or electronically. The position works under close supervision and supports team quality and production goals.

The role is on-site and requires regular, punctual attendance. Duties include minor tool setup and changing cutting tools; transferring part program files to machine controllers; following operation and planning packages, process sheets, tooling and setup sheets, program code, and blueprints; checking work with inspection tools and gauges; and stopping the process and notifying a supervisor when parts are out of tolerance. Additional tasks may include deburring, subassembly work, pressing pins or faces into components, marking or engraving parts, and other manufacturing support. The position is subject to the company's On-Call Policy and may require availability outside scheduled hours to support business needs.

The work takes place on a manufacturing shop floor, near moving mechanical parts, with daily exposure to high noise levels and temperature extremes. Employees must wear required protective clothing, including steel-toe shoes and safety glasses. The job requires frequent standing, walking, sitting, reaching, and communication; may involve repetitive arm and wrist movements, grasping and handling tools or controls, crouching, kneeling, bending, and reaching above shoulder height; and requires regularly lifting or moving items weighing up to 35 pounds. Close vision and the ability to adjust focus are required. Reasonable accommodations may be made, and certain assigned tasks may require participation in a Medical Surveillance Program.

The stated target pay range is $25.00–$27.00 per hour, depending on experience. The company may offer additional incentive compensation depending on role level or function; such payments are not guaranteed. Employment is contingent on successfully passing a background check and applicable medical surveillance requirements.
