You’ll also participate in a 1-in-4 out-of-hours callout rota, with additional work paid at the agreed overtime rate.

The position includes a minimum of one contracted Saturday per month, supporting subcontractor supervision and out-of-hours planned maintenance activities.

Your working environment

This is a static engineering role based at one dedicated client site in Norton Folgate, rather than a mobile position travelling between different locations.
