The Position
We are seeking a hands on HV Electrical Engineer to join our VIC Electrical team. This role is delivery focused and suited to an engineer who enjoys being technically involved in high voltage / medium voltage design, rather than leading teams.
Reporting to the Section Manager, you will work within a specialist HV capability while supporting broader electrical project teams across the business. The role supports a growing portfolio of mission critical, health, defence, and large-scale infrastructure projects.
This is an excellent opportunity for an engineer who wants to lead technical solutions in HV/MV systems while working on some of the most complex projects in the market.
