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.

  • Designing and contributing to:
    • HV / MV networks (typically 22kV–33kV)
    • Substations and HV reticulation
    • Transformers, RMUs, HV switchboards
    • HV generators and distribution systems
  • Preparing and contributing to:
    • Feasibility studies
    • Business cases
    • Technical reports and design documentation
  • Using industry standard power systems software to complete studies and design
  • Supporting multidisciplinary teams and collaborating with internal and external stakeholders
  • Providing technical input across mission critical (data centres), hospitals, defence facilities, and complex commercial projects
Who We’re Looking For

      • SKM Power Tools
      • ETAP (essential)
    • Ability to contribute designs to circa 50% design level and beyond
    • Experience across mission critical projects (or similar complex infrastructure) highly regarded
  • Communication & Ways of Working
    • Strong written and verbal communication skills
    • Experience preparing technical documentation, feasibility studies, and business cases
    • Collaborative team player who communicates clearly with engineers, clients, and consultants
    • Comfortable working within a nationally distributed team environment
Your Background

  • Degree qualified Electrical Engineer

  • Experience in sectors such as:
    • Mission critical / data centres
    • Health
    • Defence
    • Large commercial or infrastructure projects
