Geotech Engineer

Our client is a leading multinational coal mining company primarily involved in coal mining operations in Kalimantan Utara.

About the role

To ensure safe, stable, and cost-effective mining operations by managing all geotechnical aspects including slope design, ground control, monitoring, and risk mitigation in compliance with Indonesian mining regulations and company safety standards.

Responsibilities

• Conduct geotechnical investigations to characterize soil and rock properties, material behavior, geological structures, and groundwater assessment, including supervision of drilling, logging, and sampling activities.
• Analyze rock mass characteristics, geological structures, and subsurface conditions using accepted classification systems (RMR, GSI, SMR).
• Develop and review pit slope designs including bench, ramp, and overall slope angles.
• Design and assess waste dump stability, haul roads, and embankments.
• Perform geotechnical analysis and modelling using appropriate software (limit equilibrium / numerical methods).
• Develop 2D/3D geotechnical models to predict slope behavior under mining and environmental conditions.
• Identify geotechnical hazards such as slope instability, landslides, weak zones, and groundwater ingress.
• Conduct risk assessments and recommend mitigation measures and ground improvement solutions.
• Establish and manage slope monitoring systems including prism monitoring, slope radar, and LiDAR.
• Analyze monitoring data and implement Trigger Action Response Plans (TARP).
• Provide early warning and recommendations for potential slope failures.
• Conduct regular pit inspections to ensure compliance with geotechnical design parameters.
• Provide daily technical guidance to mine operations and drill & blast teams.
• Assess groundwater and rainfall impact on slope stability and recommend drainage and dewatering systems.
• Prepare daily, weekly, and monthly geotechnical reports and maintain proper documentation.
• Maintain geotechnical database including investigation data, laboratory results, and monitoring records.
• Coordinate with mine planning, operations, HSE, and survey teams to ensure alignment with design and safety requirements.
• Support internal audits, inspections, and government regulatory compliance requirements.
• Perform other duties as assigned by management.

Qualifications

• Bachelor's Degree in Geological Engineering, or Geotechnical Engineering.
• Minimum 8–10 years of experience in geotechnical engineering in open-pit coal mining.
• Minimum POP and POM certification
• Strong knowledge of rock mechanics, soil mechanics, and slope stability analysis
• Experience with geotechnical software such as Slide, GeoStudio, Rocscience or equivalent
• Familiarity with geotechnical monitoring systems
• Experience working in tropical and high rainfall mining environments preferred
• Strong written and verbal communication skills to prepare reports, present findings, and collaborate with the mine operations team
• Critical thinking and problem-solving skills to
• address challenges and unforeseen ground conditions
• Demonstrated awareness of the company's safety and environmental concerns.
