CNC Machinist / Programmer (5-Axis)

We’re working with a long-established precision engineering business that has built a strong reputation for delivering high-quality, technically demanding work. They operate in sectors where getting it right first time isn’t optional, and the level of investment in both machinery and people reflects that.

The machine shop is well organised, well equipped and staffed by people who know what they’re doing. It’s the kind of environment where good machinists tend to stay.

They're now looking to strengthen the team with experienced CNC Machinist/Programmers, particularly those confident working with 5-axis milling.

The Role

This is a hands-on position where you’ll be involved across the full machining process, not just stood loading parts.

  • Programming, setting and operating 5-axis milling machines
  • Working from detailed engineering drawings and CAD data
  • Producing complex components to tight tolerances
  • Inspecting your own work to ensure it meets spec
  • Carrying out finishing work where required
  • Identifying and resolving issues on the shop floor
  • Keeping machines in good condition and running efficiently
  • Supporting less experienced team members where needed

You’ll be trusted to manage your own work and contribute to maintaining high standards across the shop.

What They’re Looking For

  • Solid experience in CNC machining and programming
  • A strong background in 5-axis milling
  • Experience with Heidenhain controls would be ideal
  • Comfortable using CAM software
  • Able to read and interpret complex drawings (including GD&T)
  • Used to working in precision engineering environments
  • Someone who genuinely cares about quality and takes ownership of their work

The Work

The company manufactures complex components, both for prototype development and production. The work is varied, often challenging, and typically involves tight tolerances and high-spec materials.

If you prefer simple, repetitive machining, this probably won’t be the right fit. If you enjoy problem-solving and technical work, it will be.

What’s On Offer

£19-23 per hour

22 days holiday + bank holidays, increasing with service

Health Cash Plan

Employee Assistance Programme

A stable, well-run business with long-term work

Investment in modern machinery and continuous improvement

Why Consider It?

This isn’t a ‘bums on seats’ machining role. It’s a position in a business that values skill, experience and attention to detail — and where good engineers are recognised as such.

If you’re looking for somewhere you can get properly involved in high-quality machining, rather than just ticking boxes, it’s worth having a conversation.

If you’d like to know more, feel free to get in touch for a confidential discussion.
