  • Diagnosing faults and undertaking repairs on electrical, control, and instrumentation systems.

  • Working on pumps, motors, valves, gearboxes, compressors, dosing equipment and associated assets.

  • Maintaining and troubleshooting control panels, motor starters, VSDs and actuators.

  • Conducting testing and commissioning activities to ensure equipment performs to specification.

  • Ability to work independently and as part of a team.

  • Strong problem-solving skills with a proactive approach to maintenance.

Working Environment

This role offers a varied working environment across operational sites. While much of the work is undertaken indoors, you'll also work outdoors and in challenging environments such as chambers, tanks, raised platforms, and confined spaces.

Due to the nature of the role, a medical assessment may be required to ensure suitability for confined space and breathing apparatus activities.
