• Assist in the design of control and automation systems (SCADA, Miri) for efficient water system operation.
• Support QA/QC reviews of detailed designs and execution work undertaken by the CSI team.
• Provide engineering input during project commissioning, takeover, and handover stages.
• Collaborate with hydrogeology teams to align engineering designs with water source availability and mine plan requirements.
• Ensure designs meet regulatory, environmental, and operational requirements.
• Support operational teams post‑handover with technical advice, optimisation recommendations, and troubleshooting.

What is required?

• Tertiary qualifications in Civil, Mechanical, or Water Engineering (or closely related discipline).
• Significant experience in the design of mining or industrial water infrastructure systems.
• Proven ability to use hydraulic modelling software (WaterGEMS experience highly regarded).
• Familiarity with control/automation design for water systems (SCADA, Miri) highly regarded.
