Principal Engineer, Geotechnical & Hydrology

Job Purpose

Key Accountabilities

• Act as SME for geotechnical and hydrogeology disciplines and provide overall technical leadership
• Define preliminary slope angles, ground conditions, groundwater/dewatering assumptions, and high-level tailings methodologies during strategic, business case, and scoping stages
• Identify key risks including slope instability, ground uncertainty, and water inflow/flooding, and support initial mine planning and cost assumptions (geotechnical, dewatering, tailings)
• Lead geotechnical investigation programs (drilling, logging, ATV/OTV, lab testing) and hydrogeological assessments (aquifer behavior, pump/packer tests, water balance) during PFS
• Develop preliminary slope design parameters, ground control concepts, dewatering strategies, water handling systems, and geotechnical/hydrology risk registers with mitigation plans
• Contribute to mine design optimization and infrastructure development (TSF, plant, dumps)
• Finalize slope design criteria, ground support systems, groundwater models, dewatering design, water balance, and management strategies during FS/BFS
• Define BFS-level design parameters, CAPEX/OPEX inputs (e.g., dewatering costs, geotechnical requirements, tailings facilities), and risk mitigation measures
• Coach and mentor business development personnel and support capability development within the organization
• Ensure compliance with company and site-specific policies, standards, and procedures, and recommend improvements where required
• Provide technical expertise in geotechnical and hydrology engineering across affiliates to support effective implementation of Maaden standards
• Support the development, interpretation, and continuous improvement of Maaden policies, standards, and procedures, and assist corporate SME teams
• Contribute to technical communications (incident briefings, programs, initiatives, periodic updates) aligned with corporate standards across multiple channels
• Support EHSS programs through KPI tracking and delivery of key program requirements
• Ensure decision-ready outputs at each study stage (Scoping, PFS, FS), including on-time delivery of geotechnical and hydro scope, compliance with study requirements, quality of deliverables, and progressive improvement in accuracy
• Perform additional duties as assigned by management
