Providing principal-level technical leadership for water supply hydraulic modelling.
Leading complex network assessments that support growth, resilience, operational planning and long-term investment decisions.
Setting modelling standards for model build, calibration, validation, scenario management, reporting and handover.
Turning modelling outputs into clear advice for structure planning, development assessments, business cases, renewals, upgrades and long-term programmes.
Reviewing assumptions, input data, GIS, telemetry, field testing information and growth forecasts to improve model confidence and decision quality.
Mentoring staff and consultants to strengthen internal modelling capability and consistency of technical delivery.

Ngā Pukenga | What you’ll need to succeed

A Bachelor of Engineering in Civil Engineering, or another relevant tertiary qualification.
At least 10 years’ experience modelling complex water supply networks.
Strong technical knowledge of hydraulic modelling, network performance, demand forecasting, calibration, and scenario planning.
Experience using modelling advice to support infrastructure planning, development, operations, resilience, and investment decisions.
Confidence testing data, assumptions, model outputs, and technical recommendations.
