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.
