We partner with our customers to deliver projects and create value across the life of their assets. We specialize in consulting, engineering, procurement and construction across the project lifecycle, with services extending through to operations and decommissioning. Leveraging extensive experience and AI-enabled delivery, we support customers in navigating complexity as they meet today's needs and transition to more sustainable solutions.\nResponsibilities include:\nPerform and/or review hydrological assessments for mining infrastructure, including mine sites, haul roads, access roads, camps, stockpiles, processing facilities, and other supporting infrastructure.\nConduct catchment analysis to identify contributing catchment areas, drainage paths, flow characteristics, and potential areas of flooding or water accumulation.\nAssess rainwater runoff from natural and developed catchments and determine peak flow rates, runoff volumes, and appropriate design criteria.\nUndertake rainfall analysis, including selection of appropriate design rainfall intensity, duration and frequency (IDF) and relevant return periods.\nDevelop and review hydrological models and calculations for stormwater, surface water drainage, flood management, culverts, channels, diversion drains, detention ponds, and other water management facilities.\nReview and assess drainage strategies to manage runoff from mining areas and surrounding catchments, minimizing the risk of flooding, erosion, sedimentation, and damage to infrastructure.\nProvide technical input into the sizing and design review of culverts, open channels, drains, diversion structures, retention/detention ponds, spillways, and stormwater management systems.\nReview engineering deliverables, calculations, drawings, specifications, reports, and technical submissions prepared by EPC contractors, design consultants, and other project parties.\nProvide hydrology input to the design of roads, bridges, culverts, crossings, earthworks, and other mining infrastructure.\nReview the impact of changes in land use, topography, mine development, and infrastructure layout on catchment characteristics and rainwater runoff.\nIdentify potential hydrological risks and recommend mitigation measures during design, construction, and operation.\nCoordinate with Civil, Geotechnical, Environmental, Water Resources, Mining, and Infrastructure Engineers to develop integrated water management solutions.\nSupport PMC technical reviews, design coordination meetings, constructability reviews, and technical queries related to hydrology and drainage.\nReview contractor methodologies and proposals related to stormwater management, drainage, flood protection, and erosion control.\nEnsure hydrological designs comply with applicable Indonesian regulations, project standards, international standards, and client requirements.\nProvide technical support during construction and respond to site-related hydrology and drainage issues as required.\nAble to investigate & propose muddy river water issue from runoff\nRequirements\nBachelor’s degree in Civil Engineering, Water Resources Engineering, Hydrology, Environmental Engineering, or a related discipline.\nTypically 8-12+ years of relevant experience in hydrology, water resources, drainage, or civil infrastructure engineering.\nPrevious experience in mining, mining infrastructure, heavy industry, or large infrastructure projects is highly preferred.\nExperience working on PMC, EPCM, EPC, or Owner’s Engineer projects is preferred.\nStrong experience in catchment assessment, rainfall analysis, stormwater management, and rainwater runoff calculations.\nProven experience in hydrological and hydraulic analysis for culverts, channels, drainage systems, flood management, and water diversion structures.\nExperience with hydrological/hydraulic modelling software such as HEC-HMS, HEC-RAS, SWMM, MIKE, or equivalent is preferred.\nGood understanding of rainfall-runoff modelling, peak flow estimation, flood frequency analysis, IDF curves, catchment delineation, and flood risk assessment.\nFamiliarity with GIS tools such as ArcGIS or QGIS for catchment delineation and spatial analysis is advantageous.\nUnderstanding of erosion, sedimentation, and stormwater management associated with mining and large-scale earthworks.\nAbility to review engineering calculations, drawings, specifications, and technical reports.\nStrong coordination and communication skills, with the ability to work effectively with clients, consultants, EPC contractors, and multidisciplinary engineering teams.\nGood command of written and spoken English.\nCompliance:\nSupport the implementation and maintenance of the Environmental Management System (EMS) in accordance with ISO 14001, ensuring compliance with environmental regulations and promoting continuous environmental performance improvement.\nPromote and maintain a safe and healthy work environment by supporting the Occupational Health and Safety Management System (OHSMS) in compliance with ISO 45001, identifying hazards, assessing risks, and driving continuous improvement in workplace safety.\nSupport the implementation and monitoring of the Anti-Bribery Management System (ABMS) in accordance with ISO 37001, ensuring compliance with anti-bribery policies, due diligence, and promoting a culture of integrity and transparency.\nEmployees are expected to comply with the ISO 9001 Quality Management System by following established procedures, maintaining accurate records, and contributing to continual
