McMahon Services is continuing to grow our operations in the Northern Territory, and we’re looking for an experienced Site Manager or Supervisor to join our Darwin team.

While experience across demolition, asbestos or hazardous materials would be highly regarded, we’re also keen to hear from experienced Civil Site Managers and Supervisors who bring strong construction leadership, planning and people management capability.

For us, the ability to lead people, manage site delivery, coordinate subcontractors and resources, solve problems and create a strong safety culture is just as important as coming from one particular construction background.

If you’ve successfully managed civil construction sites and are confident you can bring those skills into a diverse project environment, we’d like to hear from you.

This is a permanent opportunity based in Darwin, offering project variety, a growing pipeline of work and the opportunity to build a long-term career with McMahon Services in the NT.
