CNC & General Machinist

Your Job

As a CNC / General Machinist, you will set up, operate, and program CNC and manual machine tools to produce high‑precision components that meet engineering, quality, and safety requirements. This role combines CNC programming expertise, hands‑on machining, and technical collaboration to support production, prototype, and continuous improvement activities.

• Set up, operate, and adjust CNC turning, CNC milling, and grinding machines to manufacture precision components
• Create, edit, and optimize CNC programs using applicable control languages (e.g., Fanuc, Siemens, Heidenhain)
• Load, set, and adjust tooling, fixtures, work holding, and offsets
• Operate manual lathes, mills, and grinders for prototype or low‑volume production when required
• Perform precision measurement using micrometers, calipers, height gauges, CMM reports, and other metrology equipment
• Interpret engineering drawings, 3D models, tolerances, and GD&T requirements accurately
• Support engineering, production, and third‑party suppliers with drawing interpretation and manufacturability guidance
• Identify potential design or process issues and communicate improvement recommendations
• Conduct first‑off, in‑process, and final inspections to ensure product quality
• Complete production documentation, inspection records, and job travelers accurately
• Maintain a clean, organized workstation and perform routine machine maintenance
• Troubleshoot machining issues, tool wear, and process deviations
• Recommend tooling, process improvements, and cost‑saving opportunities
• Collaborate with supervisors and planners to meet production priorities and deadlines

• 2–5 years of experience in CNC machining within a manufacturing or precision engineering environment (significant relevant experience may substitute for formal qualifications)
• Proven capability in CNC turning, milling, and surface/cylindrical grinding
• Ability to write, edit, and optimize CNC programs
• Strong ability to read and interpret engineering drawings, GD&T, and tolerances
• Practical knowledge of cutting tools, feeds/speeds, and machining best practices
• Ability to use a full range of precision measuring equipment
• Strong problem‑solving and troubleshooting skills
• Ability to read, write, speak, and understand English

• Experience with multiple CNC control systems (e.g., Fanuc, Mazak, Siemens, Heidenhain)
• Background in high‑precision industries such as aerospace, automotive, or electronics
• Experience using CAD/CAM software (e.g., Mastercam, Solid
  
  CAM, Fusion 360)
• Experience with prototype work, small‑batch production, or tooling manufacture
• HNC/HND or equivalent advanced engineering qualification

• Ability to sit and/or stand for extended periods (minimum 2 hours)
• Ability to maneuver throughout office, shop, warehouse, and manufacturing areas
• Ability to lift up to 50 pounds and carry up to 25 pounds
• Ability to bend, reach, kneel, twist, grip, and perform repetitive motions
• Manual dexterity and coordination to operate machinery and tools
• Ability to manage changing priorities and multiple tasks safely
• Ability to respond to visual and auditory cues
• Willingness to work in environments with occasional loud noise; PPE required on the factory floor
• Compliance with all Environmental, Health, and Safety (EHS) policies, training, and requirements
