Senior Project Engineer (PE-2) - Drainage Engineering

Core Responsibilities

• Perform complex hydrologic and hydraulic analyses, including 1D and 2D stormwater modeling using software such as HEC-HMS, HEC-RAS (1D/2D), FLO-2D, or similar.
• Congduct floodplain mapping, delineation, and regulatory compliance reviews.
• Prepare and review technical drainage reports, CLOMR/LOMR submittals, and FEMA flood map revisions.
• Utilize ArcGIS/QGIS for data analysis, mapping, and modeling support.
• Design stormwater and drainage facility designs, such as channels, culverts detention basins, storm drain systems, and erosion protection.
• Oversee the technical quality of drainage deliverables, ensuring compliance with local municipal standards, state DOT requirements, and federal (FEMA/USACE) regulations.
• Coordinate directly with clients, regulatory agencies, and sub-consultants to resolve permitting issues and technical challenges.
• Conduct rigorous QA/QC reviews of calculations, models, and design drawings prepared by junior staff.
