Waste Water Services is a specialist industrial water and wastewater treatment contractor with more than 24 years' experience supporting mining and resources operations across the Pilbara and wider Western Australia. We design, build, install, commission, refurbish, operate and maintain water and wastewater treatment assets - from packaged sewage treatment plants for remote accommodation villages through to process water systems, pumpsets, dosing systems, potable water treatment and plant upgrades. WWS holds ISO ****, ISO ***** and ISO ***** certification and, together with sister company Hiclear Australia (modular fixed-film treatment systems and civil water infrastructure), forms part of Vysarn Limited's water services group.
Position purpose
The Electrical & Control Systems Engineer owns the electrical, instrumentation and control scope across the full WWS project lifecycle from tender support, detailed design, procurement, factory and site acceptance testing, commissioning and handover for packaged and site-built water and wastewater treatment plants. The role turns process designs into protected, compliant, reliable and maintainable electrical and automation systems suited to remote, harsh-environment mining sites and backs the service and operations teams in keeping installed assets running.

Integrate and commission field instrumentation (flow, level, pressure, analytical), including loop checks, scaling and calibration records.
Support estimating and tenders with electrical and controls scoping, vendor pricing and technical proposal input.
Conduct factory acceptance tests at fabrication facilities and lead site acceptance testing and commissioning at client sites, including travel to remote Pilbara operations.
Support construction teams and electrical subcontractors with technical queries, inspections and ITP verification.
Produce commissioning plans, test records, O&M; manual content and as-built documentation to project and client requirements.
Service & operations support
Provide troubleshooting and technical support to service technicians and plant operators on installed control systems, instrumentation and electrical equipment.
