Tanami, NT, AU (Australia)


At Newmont, our purpose is to create value and improve lives through sustainable and responsible mining. One of the largest gold companies in the world, we pride ourselves on our dedication to safety, environmental management, inclusion and diversity, and adding value and opportunity to our host communities.

Newmont Tanami is on Aboriginal freehold land 540km northwest of Alice Springs. It is a long-life, low-cost, world-class asset in a core Newmont region. The Tanami Expansion 2 project, aims to extend the mine life beyond 2040, investing in a hoisting shaft which will increase the production of the underground mine from 2.6 Mtpa to 3.2 Mtpa.  Both the successful exploration within the underground operation and implementation of the first Tanami Expansion has laid the foundation to further develop the operation to remain a major contributor to the Newmont portfolio. A fully equipped camp is located 40km from the site offering modern leisure facilities for those flying in from Perth, Brisbane, Alice Springs or Darwin.


The Backfill Engineer role is based at Tanami and offers an 8/6 FIFO Roster from Perth, Darwin, Alice Springs and Brisbane.

  • Provide backfill advice within the Technical Services, Geological, Mining Operations, Surface Operations and Maintenance departments on site.
  • Focus on technical expertise in backfill design for paste, co-disposal and rockfill stopes, and the safe and timely execution of these.
  • Responsible for the numerical modelling for paste stability and hydraulic modelling for reticulation design, and implementation of this into a design package for execution.
  • Responsible for monitoring fill designs, paste plant operating trends, and laboratory data to ensure quality control and design compliance.
  • Conduct underground inspections of paste infrastructure, including reticulation, valves and bulkheads to ensure they are built to standard. 
  • Assist the team in the completion of daily paste/rockfill tracking, planning and providing backfill input into the rolling weekly mining production schedule to ensure backfill targets are achieved.
  • Actively participates and provides backfill input into medium and long term mine plans.
  • Lead and participate in backfill related projects and assist in managing contractors where required.
  • Actively look for areas to improve and add value in design, data collection and management, as well as operational improvements.
  • Assist and mentor the more junior team members and build positive relationships with all stakeholders.

The Person:

  • Strong knowledge of design packages, including Deswik and/or other Cad software.  Knowledge of FLAC-3D or other numerical modelling software, and Pumpsim highly regarded.
  • Competency in Microsoft Office.
  • Strong analytical and problem solving skills.

The Team:

The Tanami Backfill team currently comprises four engineers/technicians, and reports to the Geotechnical and Backfill Superintendent, but has regular involvement across all areas of the operation.  The team has a varied background including technical and operational experience, and shares a positive and inclusive culture.  Mining at increasing depth, and the upcoming mining of new ore bodies necessitates the expansion of the current reticulation network and an upgrade to the existing paste plant.  This creates a dynamic and engaging pipeline of work for the Backfill team and a great opportunity to upskill and develop strong technical and operational backfill skills.


Our business success comes from the accomplishments and well-being of our employees and contractors. Our goal is to build a workplace culture that allows every person to thrive, participate, grow, and proudly play an active role in achieving our strategy.
