Joining our geotechnical team, you will support safe and efficient mine operations by managing geotechnical hazards that could impact safety and business performance. Your expertise in slope design, stability analysis, and geotechnical data management will directly contribute to the success of short, medium, and long-term mine planning across the Lihir Operations.

As a Supervisor (senior equivalent) Geotechnical Design Engineer, you will play a key role in shaping safe and efficient open-pit mining operations at Lihir. You will lead geotechnical investigations, deliver high-quality slope designs, and provide expert technical guidance that supports confident mine planning and risk management. This is an opportunity to influence major operational outcomes while developing and mentoring a high-performing technical team.

You will:

• Provide technical expertise on pit slope design and slope management practices.
• Collect, interpret, and analyse geotechnical data, including core logging, sampling, field testing, geological mapping, and UAV photogrammetry.
• Conduct 2D and 3D slope stability modelling using software such as Rocscience suite (SLIDE2, SLIDE3D, RS2, RS3, DIPS, SWEDGE), FLAC 2D/3D (optional), GeoStudio, and other relevant tools.
• Prepare detailed stability analysis reports and clearly communicate recommendations to support short, medium, and long-term mine planning.
  Perform stability back-analysis for all fall-of-ground incidents and develop mitigation measures.
• Support operational teams by integrating geotechnical monitoring data and contributing to risk management decisions.
• Support mine operations in implementing and managing slope processes and systems, under the direction of the Geotechnical Superintendent.
• Collaborate with consultants and stakeholders to collect data, refine models, and integrate monitoring information for long-term slope design and risk management.
• Work with the Group Geotechnical team on slope designs with significant safety or operational implications, including LOPP and MTP projects.
• Mentor and develop team members, graduates, and trainees in modelling, slope stability analysis, and geotechnical risk management.
• Update and maintain geotechnical Ground Control Management Plan (GCMP).
• Champion proactive safety behaviours and ensure full compliance with HSE standards.

You bring strong technical expertise in geology or engineering, with hands-on experience in open-cut mine sites in both soft and hard rock. Safety, leadership, and adaptability are at the core of your approach. You take ownership of outcomes, embrace challenges, and deliver results under pressure while developing and guiding your team.

You will also bring:

• Tertiary qualification in Bachelor of Science (Geology) or Engineering (Civil or Mining).
• Currently holds, or is willing to obtain, accreditation from the Institute of Engineers Papua New Guinea (IEPNG).
• Postgraduate qualifications in geotechnical engineering or project management are desirable.
• Extensive geotechnical management experience in open-pit mining operations, including time spent in senior-level roles.
• Strong proficiency in geotechnical modelling software (Rocscience suite, GeoStudio; FLAC desirable).
• Experience with geotechnical database management (e.g., acQuire) and geological/mine planning software (Leapfrog, MineSight preferred).
• Highly proficient in MS Office applications, including advanced use of Excel for data analysis and reporting.
• Strong leadership, coaching, and interpersonal skills; able to mentor teams while embodying Newmont’s values and vision.
• Open-minded, adaptable, and able to take on diverse challenges with effective prioritisation and time management.
• Comprehensive knowledge of PNG Mine Safety Act and regulations.
• Excellent analytical, planning, problem-solving, communication, and stakeholder engagement skills.

Your work environment

This role is based at Newmont’s Lihir Operations in Papua New Guinea and follows a 22:20 Fly-In, Fly-Out (FIFO) roster to Lihir Island. The position primarily operates on a day shift, with occasional night shift callouts as required.

You will work closely with the Geotechnical, Mine Operations, and Planning teams in a dynamic open pit environment. The role provides exposure to technically challenging geotechnical conditions and offers the opportunity to influence large-scale, complex mining projects.

Our FIFO employees stay in a secure and comfortable camp, in an en-suited and airconditioned room equipped with mini fridge, TV and Wi-Fi. A variety of healthy meal options are catered for at our mess; and the wet mess provides a relaxed social setting where employees can unwind with a game of pool or darts.

Why Join Newmont

• Be part of one of the world’s leading gold mining companies with a strong commitment to safety, sustainability, and community.
• Work within a collaborative team of technical specialists and leaders who value innovation and continuous improvement.
• Access opportunities for professional development, career mobility, and leadership growth.
