Principal Engineer - Hydraulic Engineering

We are seeking a highly skilled, collaborative, and analytical Senior Hydraulic and Hydrological Modelling Engineer to join our Wet Utilities team. In this role, you will lead complex 1D and 2D integrated modeling projects, capacity assessments, and optioneering for wet utility networks, cross-discipline highway/roads infrastructure (T&I), and groundwater systems, primarily serving our Nordic business lines. You will leverage DHI's MIKE Plus suite, TUFLOW, and MIKE SHE to simulate urban drainage, culvert hydraulics, water accumulation, cloudburst events, and integrated groundwater-surface water interactions, while driving engineering efficiency and mentoring junior engineering staff.

Responsibilities:

• Core Network & Asset Modelling: Construct, execute, and verify complex 1D and 2D urban water, wastewater, storm drainage network, and river models using DHI MIKE Plus, TUFLOW, and ArcGIS.
• Infrastructure & Culvert Hydraulics: Perform specialized culvert modeling, crossing assessments, and hydraulic evaluations to support major Transportation & Infrastructure (T&I) roads and highway projects.
• Integrated Groundwater Modelling: Develop and apply MIKE SHE models to simulate comprehensive hydrological cycles, focusing on groundwater-surface water interactions, water table variations, and impact assessments for infrastructure.
• Technical Governance & Quality: Establish the technical direction for complex modeling studies. Resolve complex technical issues that arise during project execution, ensuring overall design integrity across disciplines (Highways, Bridges, Geotechnical, and Utilities).
• Capacity Assessment & Optioneering: Evaluate system performance, identify deficiencies, and engage with team members to develop optimal, cost-effective design solutions (including software-migration workflows) spanning from feasibility studies to detailed design stages.
• Advanced Calibration & Verification: Update and calibrate models using asset data, manhole details, CCTV, borehole logs, and flow surveys to ensure high-fidelity predictive outputs.
• Flood, Cloudburst & Sustainable Drainage: Build dynamically linked 1D-2D models to simulate overland flow paths, cross-drainage assets, surface water accumulation, urban flooding hazards, and Sustainable Urban Drainage Systems (SuDS).
• Automation & Leadership: Develop scripts (e.g., Python, SQL) to automate data extraction, GIS integration, and model workflows. Actively supervise, guide, and support the professional growth of Graduate and Junior Engineers.
• Stakeholder Communication & Reporting: Maintain clear, proactive communication with the lead business, writing robust technical reports and documentation detailing modeling methodologies, findings, and strategic recommendations.
