• Undertake minor modifications to process automation and control systems as required to support regulatory compliance and process continuity.
• Undertake preventive maintenance activities on OT field hardware, systems/networks.
• Perform firmware and software upgrades/patching of OT equipment to maintain security controls and compliance.
• Support Water and Water Recycling operational teams during planned maintenance activities to ensure OT assets are correctly shut down and brough back online to mitigate operational impact.
• Undertake site surveys, installation and commissioning of OT hardware, systems and networks.
• Perform minor PLC modifications and Telemetry IO wiring changes to support the introduction of new instrumentation and plant.
• Provide technical on-site support to OT framework partners for the service integration of new, and or modified OT field hardware, software, systems and networks.
