Senior Engineer, Water Resources

Bowman Consulting is seeking a Senior Engineer in Water Resources to join their team remotely. The role involves carrying out complex hydrologic and hydraulic modeling assignments, contributing expertise in watershed-scale and site-scale modeling to support infrastructure evaluation and regulatory compliance.

Responsibilities:

• Receive broad guidance from senior-level management relating to overall key objectives, critical issues, new concepts and policy matters, with flexibility for independent execution of complex modeling tasks
• Manage people and processes to ensure effective execution
• Review and provide quality assurance for modeling work and technical deliverables produced by staff
• Assist with the marketing of the firm’s capabilities to establish new clients and enhance relationships with existing clients
• Coordinate with other internal departments to meet project requirements
• Drive the profitability and growth of projects
• Support marketing and business development efforts by showcasing modeling and water resources capabilities to new and existing clients
• Collaborate with senior engineers, regulatory agencies, subcontractors, and design teams on technical issues related to hydrology and hydraulics
• Apply advanced and diversified knowledge of hydrologic and hydraulic engineering principles across a wide range of project types
• Develop, calibrate, and apply 1D and 2D hydrologic/hydraulic models (e.g., HEC-HMS, HEC-RAS 1D/2D, Flo2D, SRH-2D, TUFLOW, PCSWMM, StormCAD) for rainfall–runoff, channel hydraulics, floodplain delineation, and stormwater infrastructure evaluation
• Conduct watershed-scale and site-scale analyses, including hydrologic parameter calibration (CN, infiltration, lag time, baseflow) using gage records, LiDAR, and soil datasets
• Generate and refine 2D computational meshes, break lines, and boundary conditions; conduct sensitivity analyses to evaluate flood depth, velocity, and scour potential
• Prepare CLOMR/LOMR packages and coordinate with FEMA and regulatory agencies for floodplain mapping, compliance, and permitting
• Integrate GIS and scripting tools (ArcGIS/QGIS) with hydrologic/hydraulic models for terrain processing, land cover classification, and spatial data analysis
• Apply statistical hydrology techniques such as Bulletin 17C frequency analysis, NOAA Atlas 14 precipitation studies, and regional regression equations
• Provide design input for stormwater BMPs, detention/retention systems, and green infrastructure with a focus on hydrologic/hydraulic performance
• Prepare technical memoranda, hydrographs, reports, and model documentation for agency and client submittals
• Communicate complex modeling results to multidisciplinary teams, stakeholders, and regulators, and provide defensible recommendations

Requirements:

• Master's Degree in Hydrology, Water Resources, or Civil/Environmental Engineering with a focus on surface water processes required
• Eight or more (8+) years of professional experience applying 1D and 2D hydrologic/hydraulic models to complex watershed and site-scale projects
• Advanced experience with HEC-HMS, HEC-RAS (1D/2D), and other modeling platforms (Flo2D, SRH-2D, TUFLOW, PCSWMM, StormCAD)
• Proficiency in hydrologic parameter development and calibration using gage data, LiDAR, and soils datasets
• Strong GIS integration skills with QGIS/ArcGIS for terrain processing, land cover, and model inputs
• Experience with CLOMR/LOMR preparation and coordination with FEMA
• Knowledge of stormwater BMP design, detention/retention, and green infrastructure analysis
• Familiarity with statistical hydrology, including Bulletin 17C, NOAA Atlas 14, and regional regression approaches
• Experience preparing technical reports and compliance documentation for local, state, and federal agencies
• Proficiency in Microsoft Office Suite (Word, Excel, PowerPoint, Outlook, Projects)
• Professional Engineer (PE) license preferred
