We are currently seeking a Senior Hydrology Engineer for a portfolio of mobility/railway projects in Dammam, KSA.
The engineer will lead hydrologic and hydraulic design across feasibility, concept, and detailed design stages. Responsibilities include rainfall-runoff modeling, peak flow estimation, and design of stormwater systems (channels, culverts, pipes, detention/retention basins, swales, oil-water separators). They will perform hydraulic structure sizing and backwater analyses, floodplain mapping, scour assessment, and conveyance system optimization. Designs will consider arid-climate extremes, flash flooding, wadis, sabkha conditions, and climate change scenarios.
Responsibilities
- Provide specialist input for transport corridors, including track formation drainage, subgrade protection, cross-drainage structures, cut/fill slope drainage, station and depot stormwater systems, and highway interchange drainage.
- Coordinate with civil/track, geotechnical, bridges, and road design teams to manage interfaces and maintain operability under extreme events. Experience with hydrology for embankments, culverts under rail, and hydraulic impacts on structures is advantageous.
- Ensure designs comply with KSA and Gulf authority requirements, relevant international codes (e.g., AASHTO, BS/EN, Eurocodes), and client-specific standards.
- Prepare technical reports, design calculations, and drawings suitable for authority review; support permitting, NOC's, and stakeholder approvals; and integrate environmental and sustainability considerations, including water-sensitive urban design where applicable.
- The role includes model-based workflows using GIS, BIM, and CDE platforms. The engineer will review hydrologic/hydraulic models, maintain data integrity, and contribute to standard libraries and design templates.
- Participate in design reviews, HAZID/HAZOP where relevant, value engineering, and quality management processes, ensuring traceable assumptions and auditable calculations.
- Work closely with multidisciplinary teams, coordinate inputs from survey, geotech, roads/rail, structures, and environmental specialists, and provide clear design briefs to CAD/BIM teams.
- Present technical findings to clients and stakeholders, support responses to RFIs, and contribute to proposal inputs and level-of-effort estimates for hydrology scopes.
Qualifications and Experience
- Candidates must have approximately 10 years of professional experience in hydrology/hydraulics design, with mandatory experience in the Gulf or Saudi Arabia.
- A bachelor's degree in civil engineering, water resources, or environmental engineering is required; a master's degree is an advantage.
- Proven delivery of drainage and flood solutions for infrastructure projects is essential. Railway or transportation corridor experience is a strong advantage, including cross-drainage structures and corridor drainage systems.
- Familiarity with KSA/GCC authority standards and permitting processes is required.
- Proficient with hydrologic and hydraulic software such as HEC-HMS, HEC-RAS (1D/2D), SWMM/StormCAD/SewerGEMS/CivilStorm, MicroDrainage, and GIS tools (ArcGIS/QGIS). Experience with AutoCAD/Civil 3D and BIM coordination is expected.
- Strong capability in rainfall analysis (IDF curves), hydrograph development, infiltration and storage design, flood routing, sediment/scour considerations, and climate-resilience assessments is needed.
- The role demands rigorous technical judgment, attention to detail, and clear communication. The engineer should demonstrate problem-solving skills, stakeholder engagement, multidisciplinary coordination, and the ability to translate complex modeling into practical, buildable designs.
- A proactive approach to risk, constructability, and maintenance outcomes is essential.
