CNC Machinist

Machinist

QCi is seeking an experienced machinist to operate and manage a CNC machine shop. This person will be responsible for setting up and operating a 5-axis CNC mill to fabricate precision parts. Responsibilities include selecting tools, monitoring production, and inspecting parts while adhering to all necessary safety requirements. This role requires independent problem-solving: you will be expected to think critically, troubleshoot issues, and determine the best approaches for manufacturing precision components across a range of materials. When production demand slows, you may assist with fabrication projects, equipment support, tooling improvements, or other operational and technical initiatives across the facility.

Duties and Responsibilities:

• Machine setup: align, secure, and adjust cutting tools, fixtures, and raw materials into CNC machines
• Programming & operation: load, edit, or program instructions (G-code/M-code) to determine cutting paths, speeds, and feed rates
• Quality control: measure, examine, and test completed products for defects using precision tools like calipers and micrometers
• Technical interpretation: read and interpret mechanical drawings, CAD files, and engineering specifications
• Maintenance & safety: perform routine maintenance on machines, clean work areas, and ensure compliance with safety and 5S standards
• Troubleshooting: monitor machine performance, adjust settings and process parameters to correct issues and prevent production errors
• Collaboration: work with engineering teams to improve manufacturability, reduce cycle time, minimize scrap, and support prototype and production needs
• Post-processing: lead implementation of post-processing steps such as media blasting, anodizing, plating, and other surface treatments to ensure final part compliance
• Assist with additional operational or technical fabrication projects during lower machining volume periods

Required Skills and Experience:

• 3+ years of experience as a CNC machinist in a precision manufacturing environment
• In-depth knowledge and hands-on experience operating a 5-axis CNC mill, or advanced 3-axis machining experience with demonstrated exposure to 5-axis concepts and setup
• In-depth knowledge of CAD/CAM software packages; SolidWorks and CAMWorks preferred
• Experience working with tight tolerances and high-precision components
• Proficiency generating and interpreting mechanical drawings and engineering specifications

Preferred Qualifications:

• 5+ years of CNC machinist experience
• Background in semiconductor, aerospace, advanced manufacturing, or other high-precision industries
• NIMS machining certification
• Experience machining non-standard materials such as stainless steel, Inconel, oxygen-free copper, molybdenum, Teflon, or ceramics
• Experience with post-processing methods and surface treatments
