Job summary

McLaren Automotive is seeking a skilled CNC Programmer to create, validate, and optimise CNC programs for composite machining at the McLaren Composite Technology Centre. You will convert CAD models into efficient toolpaths that meet quality, dimensional, and surface finish targets while maximizing cycle time and tool life.

You'll collaborate with design and manufacturing teams, select tools and parameters, post-process and simulate programs, verify with VERICUT, and support first-off

Qualifications

• Proven experience creating and optimising CNC programs in a production machining environment.
• High proficiency in CAD/CAM with experience generating/validating complex toolpaths (Mastercam/PowerMill advantageous).
• Strong knowledge of multi-axis CNC machining, including 5-axis equipment.

Responsibilities

• Create, edit, and optimise CNC programs and multi-axis toolpaths.
• Interpret drawings, CAD models, tolerances, datum structures, materials, and surface-finish requirements.
• Select tools, parameters, work offsets, probing routines, and safe machining sequences.
• Post-process, simulate, and verify programs to identify collisions and risks before release.
• Support prove-out, analyse measured results, and revise programs to meet requirements.
• Optimise toolpaths, feeds, speeds, stepovers, and sequences to improve cycle time, tool life and reliability.
• Create and maintain CNC programming docs (program files, setup sheets, tooling lists, work offsets, revision records).
• Troubleshoot CNC programs and toolpaths, implementing robust corrections.
• Maintain program libraries, naming conventions, and data integrity.
• Contribute to standardisation and continuous development of CNC methods and post-processors.
