The opportunity

We're launching a dedicated service and maintenance division, and we're looking for the engineer who will grow with it.

Solid experience servicing and fault-finding on commercial systems (Mitsubishi Electric, Daikin and Samsung experience a plus)

Confidence dealing directly with clients and facilities managers

Organised, reliable and proud of the quality of your work

The ambition to step into a leadership role

What you'll get

Company van

Pension and the usual benefits

A clear route to Service Lead as the division grows

Variety, with different sites and challenges rather than one job for months

A growing company where your input shapes how things are done
