About the role

DT Infrastructure is proud to be delivering the Perth High Capacity Signalling (HCS) Project, a landmark $1.6 billion METRONET initiative that will transform the city’s rail network.

• Participate in planned and reactive maintenance activities
• Work collaboratively with signalling, engineering, and operations teams
• Participate in on-call and/or shift rosters as required
