Description
Job Summary:
The Senior Geotechnical Engineer monitors, analyzes, and controls the geotechnical conditions of an open-pit mine, with a focus on slope stability and risk management.
Key Highlights:
1. Close collaboration with Geology, Mine Planning, and Operations departments
2. Preparation of technical analyses and monitoring of geotechnical indicators
3. Technical support for risk and safety management in mining
**Summary of Responsibilities:**
The Senior Geotechnical Engineer will be responsible for monitoring, analyzing, and controlling the geotechnical conditions of an open-pit mine, focusing on pit slope and associated structure stability. The role involves interpreting monitoring data, conducting geotechnical studies, and providing technical support to Planning and Operations teams, thereby contributing to safe decision-making and operational geotechnical risk management.
This professional will work closely with Geology, Mine Planning, Operations, and SSMA departments, supporting continuous assessment of pit geotechnical performance, definition of operational controls, and preventive identification of potential instabilities.
Additionally, the role includes preparing technical analyses, monitoring geotechnical indicators, and participating in implementing monitoring, inspection, and risk management practices aligned with operational technical and safety standards.
**Key Activities:**
* Conduct applied geotechnical and geomechanical studies related to pit slope stability and other mine structures;
* Update and interpret 3D geotechnical models, including structural models and rock mass classifications;
* Perform stability analyses using Limit Equilibrium Methods (LEM) and numerical analyses via Finite Element Method or Finite Difference Method (FEM/FDM);
* Execute and interpret data from geotechnical instrumentation, such as piezometers, prisms, total stations, and monitoring systems;
* Evaluate geotechnical trends and behaviors, identifying anomalies and proposing technical mitigation recommendations;
* Conduct periodic field geotechnical inspections to verify stability conditions, geometric conformity, and preventive identification of instabilities;
* Perform field geomechanical mapping using classifications such as RMR, GSI, and Q\-System;
* Support short- and medium-term mining planning through geotechnical recommendations and constraints;
* Monitor geotechnical performance indicators related to slope behavior, benches, and post\-blasting stability;
* Assess the performance of surface and subsurface drainage systems within the pit;
* Participate in analysis and monitoring of geotechnical risks associated with mining operations;
* Prepare technical reports, expert opinions, technical notes, and records of geotechnical inspections and analyses;
* Provide technical support to Operations, Planning, SSMA, and Risk Management departments;
* Participate in internal and external audits related to operational geotechnical management.
**Required Qualifications:**
* Bachelor’s degree in Geology, Geological Engineering, or Mining Engineering;
* Experience in geotechnics applied to open-pit mining operations;
* Knowledge of rock mass geomechanical mapping and classification (RMR, GSI, Q\-System);
* Experience in slope stability analyses using Limit Equilibrium Methods (LEM);
* Knowledge of geotechnical modeling and structural interpretation;
* Hands-on experience with instrumental geotechnical monitoring and interpretation of instrumentation data;
* Experience with geotechnical analysis and modeling software.
**Preferred Qualifications:**
* Experience with numerical analyses using Finite Element Method or Finite Difference Method (FEM/FDM);
* Familiarity with Rocscience suite software (Dips, Slide, RS², RocSlope2, RocFall2, RSData);
* Experience with Leapfrog Geo, Deswik, or QGIS software;
* Knowledge of hydrogeology applied to mining;
* Experience with waste rock dumps or ore stockpiles;
* English proficiency is considered an advantage.
**Additional Information:**
* Work schedule: 14 days on / 14 days off; FIFO;
* Transportation, accommodation, and meals provided by the company.
