CNC Machinist (5-axis Milling)

Responsibilities

• Set, operate, and optimise 5‑axis CNC milling machines to manufacture complex precision components
• Interpret engineering drawings, CAD models, and technical specifications, including GD&T
• Produce parts to extremely tight tolerances in materials such as titanium, aluminium, stainless steel, and high‑performance alloys
• Select appropriate cutting tools, workholding, and fixtures
• Make on‑machine program edits and offset adjustments where required
• Work with CAM‑generated programs, collaborating with programmers to improve machining efficiency, quality, and cycle time
• Perform first‑off and in‑process inspections using precision measuring equipment (micrometers, verniers, gauges)
• Ensure all machining activities comply with aerospace and defence quality standards and procedures
• Troubleshoot machining issues and support continuous process improvement
• Maintain machine performance through routine checks, maintenance, and good housekeeping
• (Senior level) Support and mentor junior machinists and operators where required

Requirements

• Strong CNC machining experience with a focus on 5‑axis milling
• Experience machining for aerospace, defence, motorsport, or similarly regulated industries
• Ability to read and interpret complex engineering drawings and GD&T
• Solid understanding of tooling, workholding, and cutting strategies
• Experience using precision inspection equipment
• Working knowledge of CNC controls such as Siemens, Fanuc, or Heidenhain
• Ability to work independently while maintaining high quality and delivery standards
• Strong problem‑solving skills and attention to detail

Preferred

• Experience using or working alongside CAM software (e.g. Hypermill, Siemens NX)
• Experience across prototype, low‑volume, and higher‑volume precision manufacturing
• Knowledge of AS9100 or aerospace quality systems
• Experience in fast‑paced R&D or startup environments
