We are seeking a skilled CNC Mill Machinist with experience machining plastic components in a high-mix, low-volume production environment. This role involves frequent setups and operation of CNC milling machines to produce precision parts from a variety of plastic materials. The ideal candidate thrives on variety, has strong technical aptitude, and takes pride in delivering high-quality, one-off and short-run parts. 

Essential Functions: 

• Setup, program, and operate CNC milling machines to produce precision plastic components per print and job specs. 

• Perform frequent machine changeovers efficiently due to the low-volume nature of the work. 

• Make adjustments to cutting tools, speeds, and feeds. 

• Use precision measuring tools (calipers, micrometers, height gauges, etc.) to inspect parts and ensure tight tolerances are met. 

• Work with Programming to troubleshoot machining issues related to plastic properties, such as melting, warping, or surface finish defects. 

• Maintain detailed setup sheets, program files, and inspection records for repeatability. 

• Support continuous improvement initiatives in machining processes, tooling, and fixture design. 

• Perform routine machine maintenance and cleanliness to ensure equipment reliability. 

Qualifications: 

• Minimum of 5 years of CNC milling experience, preferably in a job shop or plastic machining environment. 

• Deep understanding of machining plastics—including material behavior, fixturing considerations, and chip control. 

• Ability to work independently on short-run or prototype work with minimal supervision. 

• Solid knowledge of cutting tool selection and tool life optimization. 

• Ability to read and interpret blueprints, tolerances, and GD&T symbols. 

• Experience with 3-axis and 5-axis milling machines (e.g., Haas, Brother, Doosan or similar). 

• Familiar with machining tight tolerance plastic parts. 

• Comfortable assisting with fixture design and setup optimization. 

• Prior experience in a regulated or quality-driven environment (e.g., ISO 9001). 

Work Environment: 

• Exposure to loud noise, moving mechanical parts, and varying temperatures. 

• Personal protective equipment (PPE) required. 

• Hands-on role requiring standing, manual dexterity, and occasional lifting of materials or fixturing. 

• Ability to stand for extended periods. 

• Ability to lift up to 40 lbs repetitively. 

• Strong emphasis on quality, safety, and craftsmanship. 

• This position may involve exposure to, but is not limited to, the following materials: acrylic, polycarbonate, FR-4 epoxy glass, GPO (I, II, III) polyester glass, HDPE (high-density polyethylene), glass epoxy, G9 glass melamine laminate, copper, brass, and aluminum. 

Schedule: 

• 2nd Shift – 2 pm to 10:30 pm 

Compensation and Benefits: 

• Competitive hourly wage/salary based on experience. 

• We offer excellent wages and comprehensive benefits including Medical Insurance, Dental Insurance, Vision Insurance, Life Insurance, Disability Insurance, Paid Holidays, Vacation, and 401(K) with Employer match up to 4%.
