To create, validate, maintain, and optimise safe, accurate CNC programs for composite machining processes at the McLaren Composite Technology Centre.

As a CNC Programmer, your responsibilities will include:

Creating, editing, and optimising CNC programs and multi-axis toolpaths using approved CAD/CAM software.
Interpreting engineering drawings, CAD models, tolerances, datum structures, material specifications, and surface-finish requirements to define appropriate machining strategies.
Selecting cutting tools, holders, machining parameters, work offsets, probing routines, and safe machining sequences.
Post-processing, simulating, and verifying programs to identify collisions, over-travel, gouging, and other machining risks before release.
Supporting program prove-out and first-off manufacture, analysing measured results, and revising programs until requirements are achieved.
Optimising toolpaths, feeds, speeds, stepovers, and machining sequences to improve cycle time, tool life, quality, and process reliability.
Creating and maintaining controlled CNC programming documentation.
Troubleshooting CNC program and toolpath issues, implementing robust programming corrections where required.
Maintaining approved program libraries, naming conventions, revision control, and data integrity.
Contributing to the standardisation and continuous development of CNC programming methods, templates, post-processors, and best practice.

Functional / Technical Skills:

Proven experience creating and optimising CNC programs in a production machining environment.
High proficiency in at least one recognised CAD/CAM package, with experience generating and validating complex toolpaths.
Experience using Mastercam and PowerMill is advantageous.
Strong knowledge of multi-axis CNC machining, including 5-axis equipment.
Experience programming CNC machining of composite materials is highly advantageous.
Ability to interpret engineering drawings, CAD models, geometric tolerances, datum structures, and surface-finish requirements.
Sound understanding of cutting tools, tool holding, workholding, probing, offsets, feeds, speeds, depths of cut, and machining strategy.
Experience using simulation and verification software, such as VERICUT.
Working knowledge of G-code, M-code, post-processors, and relevant CNC machine controls.
Experience preparing clear setup sheets, tooling lists, program notes, and revision-controlled programming records.
Strong troubleshooting skills with a methodical approach to program prove-out, correction, and optimisation.

Personal Attributes / Competencies:

Self-motivated and capable of working effectively both independently and collaboratively within a team.
Adaptable to a dynamic and fast-paced environment.
Strong communication and interpersonal skills.
Effective in influencing, negotiating, and resolving conflicts.
Flexible and open-minded approach to tasks and responsibilities.
