We are ERO, a mining company born in the heart of Brazil that has grown to bring more strength and energy to the world—a strength that drives productive sectors and contributes to the development of different regions. Since 1979, when it began operations at the Caraíba unit, the company has been consolidating its presence in the Brazilian mineral sector, expanding into the Xavantina gold mine and advancing the implementation of the Tucumã unit—which stands out as one of the country's major copper production hubs. Our growth is driven by exploration expertise, which helps extend the life of our mines and advance new projects such as the Furnas Project in Pará. Our approach to mining is guided by strong values: care, courage, honesty, collaboration, and excellence. These principles are central to everything we do—from the mine floor to strategic decisions. They also guide how we support the growth of every individual at Ero. Our goal is clear: to be the best mining company in Brazil, and we know this is only possible by investing in the people who build this future with us every day. **Do you relate to this?** We are seeking a **Senior Geotechnical Engineer** responsible for integrating geotechnics into medium/long-term planning (LOM) and operational strategy, ensuring compliance with international standards and promoting a culture of continuous improvement and operational excellence. **Work location:** Pilar – Jaguarari/BA **Employment model:** Full-time, CLT | On-site **Management:** GEGET (for internal use) **Responsibilities and duties** * Integrate geotechnics into medium/long-term planning (LOM) and operational strategy; * Actively engage across all three units (Pilar, Vermelhos, and Surubim), assessing the feasibility of new mining projects, leading advanced numerical modeling, promoting continuous improvement, and supporting management in high-impact decision-making; * Establish medium- and long-term technical guidelines and ensure geotechnical development aligns with the company’s safety, productivity, and sustainability objectives; * Assess the geotechnical feasibility of new underground and open-pit mining areas; * Analyze geomechanical conditions related to elevation advancement, depth, or lateral expansion of mining fronts; * Actively participate in long-term planning and project routines, ensuring strategic decisions align with stability and safety criteria; * Plan, coordinate, and validate 2D and 3D numerical models (RS2, FLAC3D, MAP3D, etc.) focused on predicting long-term geomechanical behavior; * Evaluate hypothetical excavation, support, and interaction scenarios with geotechnical structures over multi-year horizons; * Identify latent risk zones that could compromise the mine’s future viability; * Lead or support structural projects such as redesigning support strategies, reviewing geotechnical mining sequencing criteria, defining exclusion or restricted zones, and integrating geotechnics with hydrogeology and structural geology; * Participate in internal and external audits focused on medium- and long-term plans; * Contribute to the review and update of company policies, technical standards, and geotechnical guidelines; * Promote the introduction of new technologies applicable to geomechanical behavior prediction (e.g., machine learning, predictive dashboards, etc.); * Evaluate benchmarks and technical case studies from other operations for local application; * Encourage the creation of technical maturity and predictive performance indicators in geotechnics; * Issue strategic assessments on future risks and their mitigation; * Provide technical guidance on prioritizing future geotechnical investigation areas (drilling, testing, long-term instrumentation). **Requirements and qualifications** * Bachelor’s degree in Mining Engineering, Geological Engineering, or Geology; * Active CREA registration; * Experience in underground mine geotechnics and proficiency with geotechnical software; * Knowledge of instrumentation, seismic monitoring, and numerical modeling; * Desirable experience in open pits; * Postgraduate degree or master’s in Geotechnics is desirable; * Driver’s license: Category B. **Additional information*** Competitive salary * Profit-sharing (PLR) * Private pension plan * Medical insurance * Dental coverage * Life insurance * On-site meals (at operational sites) * Meal allowance (at offices) * Food allowance * Transportation * Quality of Life Program * Gympass – Wellhub * Extended maternity and paternity leave (Citizen Company) * Club membership agreement—may vary by location * Eyewear purchase assistance for family members #### **We are Ero, one of Brazil’s leading producers of copper and gold.** **We belong to a global group headquartered in Canada with a strong presence in Brazil.
