## About the Role

A completed engineering apprenticeship in CNC machining, or an equivalent qualification such as an NVQ Level 3, BTEC or HNC in mechanical or manufacturing engineering.

Hands-on experience setting and operating CNC milling or CNC turning machines. Experience of both is an advantage.

Good working knowledge of cutting tools, inserts, grades and tool holding, and how they perform across different materials.

Confident reading engineering drawings, including tolerances and surface finish requirements.

A sound understanding of speeds and feeds. Familiarity with common CNC controls such as Fanuc, Heidenhain, Siemens or Mazatrol is desirable, as is CAD/CAM awareness.

A clear, confident communicator who is comfortable talking to machinists, programmers and buyers.

Organised and computer literate, able to manage several enquiries at once and follow them through.

Keen to move from the shop floor into a technical support role. Previous sales or office experience is not essential.

## Description

The Internal Technical Support Engineer is the office-based technical voice of Matrix. You will advise customers and colleagues on tooling selection and application, turning your hands-on CNC machining experience into practical recommendations.

This is an ideal next step for a time-served machinist who wants to move off the shop floor into a technical, customer-facing role. Full product and supplier training is provided.

Key responsibilities

Act as the first point of technical contact for customers, the internal sales team and field-based engineers, by phone and email.

Recommend the right cutting tools, grades, geometries and tool holding for milling, turning, drilling and threading applications.

Advise on cutting data, including speeds, feeds and depths of cut, to suit the customer's material, component and machine.

Troubleshoot machining problems such as poor tool life, surface finish, vibration and chip control, and propose practical solutions.

Interpret engineering drawings and component requirements to identify standard or special tooling, liaising with suppliers where needed.

Prepare technical quotations and tooling proposals, including cost-per-part and productivity comparisons.

Support the external technical sales engineers with tooling trials, test reports and customer follow-up.

Keep product knowledge current through supplier training, and record enquiries and recommendations accurately on company systems.
