Job Overview
A well-established precision engineering and manufacturing company is seeking an experienced CNC Programmer to join its team. This position is focused exclusively on CNC programming for complex machining applications and requires a candidate with exceptional technical ability, analytical thinking, and attention to detail.
The successful candidate must have proven experience programming 4-axis CNC milling machines using CAD/CAM software. The role is best suited to an individual who enjoys solving complex machining challenges, optimising manufacturing processes, and producing high-precision components.Key Responsibilities

• Develop, create, and optimise CNC programs for 4-axis milling machines.
• Generate machining programs directly from engineering drawings and 3D CAD models.
• Utilise CAD/CAM software such as Mastercam, Autodesk Inventor CAM, Siemens NX, or similar programming platforms.
• Determine machining strategies to maximise efficiency, quality, and tool life.
• Select appropriate cutting tools, tooling strategies, feeds, and speeds.
• Interpret complex engineering drawings, GD&T, and technical specifications.
• Troubleshoot machining and programming issues while implementing effective solutions.
• Verify and simulate CNC programs before production.
• Work closely with engineering and production teams to improve machining processes.
• Continuously identify opportunities to reduce cycle times and improve manufacturing efficiency.
• Ensure all programs comply with quality and safety standards.

Minimum Requirements

• Proven experience programming 4-axis CNC milling machines.
• Strong CAD/CAM programming experience using software such as:
• Mastercam
• Autodesk Inventor CAM
