Senior / Principal Hydrogeology Engineer

Job Description WSP in the Middle East are seeking an experienced Senior to Principal Hydrogeology Engineer to join our growing P&B Ground Engineering team in Riyadh, KSA. The role will provide technical leadership across groundwater projects, lead multidisciplinary coordination, and deliver high-quality hydrogeological assessments and groundwater management and control solutions. Responsibilities Project & Team Management • Manage project delivery, ensuring compliance with scope, schedule, budget, and quality standards. • Lead coordination meetings with clients, contractors, and stakeholders. • Mentor junior engineers and provide technical oversight and quality assurance. • Contribute to proposals and business development initiatives. Technical Leadership • Lead hydrogeological groundwater assessments, including evaluation of groundwater rise and long-term impacts on infrastructure. • Interpret and review packer tests, falling/rising head tests, and pumping test data to assess aquifer parameters, safe yield, and well performance. • Develop, calibrate, and review 3D groundwater flow and solute transport models (MODFLOW 6 work experience (GMS and Python-based modelling), MT3DMS, FEFLOW, or equivalent). • Perform water balance and mass balance assessments to support sustainable groundwater management. • Apply GIS tools (ArcGIS, QGIS) and Python/FloPy to enhance data analysis, visualization, and modelling workflows. Dewatering & Groundwater Control • Lead the design and review of construction dewatering systems and long-term groundwater control solutions. • Prepare and oversee design calculations, drawings, BOQs, specifications, and tender documentation. • Develop and review hydrogeological reports, dewatering plans, and groundwater impact assessments. Mining-Specific Expertise (advantage) • Experience in mining hydrogeology, including open-pit and underground operations, is highly desirable. • Conduct hydrogeological assessments for mineral extraction projects, including ore body dewatering, and groundwater flow modelling and feasibility studies, risk assessment studies, TSF subsurface water management design. • Advise on long-term mine water management, recharge and discharge strategies, and integration with local water resources. • Support closure and post-mining groundwater management planning. Qualifications • Bachelor’s or Master’s degree in Hydrogeology, Civil Engineering (Water Resources), or a related field. • 6–12 years of experience in hydrogeological engineering, groundwater modelling, dewatering design, and groundwater management. • Strong leadership, project management, and client-facing experience. • Proven ability to lead multidisciplinary teams and successfully deliver complex groundwater projects. • Demonstrable experience delivering hydrogeology and groundwater projects in KSA or the wider Middle East, ideally across major infrastructure, buildings, or large-scale development programmes. • Strong understanding of groundwater investigation, aquifer testing, numerical groundwater modelling, dewatering systems, groundwater control, and associated geotechnical interfaces. • Experience working with clients, contractors, authorities, and multidisciplinary design teams in KSA, with the ability to provide technical leadership from assessment and design through to construction support.
