We are seeking a motivated Water Resources Engineer / Modeler to join our team and support a wide range of water resources projects involving advanced hydrologic and hydraulic modeling.

This role blends hands-on engineering design with complex 2D H&H analysis , making it ideal for an engineer who enjoys both technical modeling and practical infrastructure problem solving.

Projects may include developing solutions to challenging flooding issues using a variety of analysis tools including 2-Domensional modeling.

Solution development generally includes detention basins, drainage channel improvement, storm sewer improvements, and surface conveyance improvements (neighborhood streets).

The successful candidate will collaborate closely with engineers, modelers, and CADD staff to deliver high-quality drainage studies that will transition into construction documents.

If you’re looking for a role that offers mentorship, technical growth, and collaboration—while allowing you to apply real engineering judgment—this could be a great fit.

• Perform hydrologic and hydraulic analyses for riverine systems, urban drainage, floodplain mapping, and stormwater management projects.
• Develop and implement 1D/2D hydraulic models using tools such as HEC-RAS (1D/2D), TUFLOW, XPSWMM, InfoWorks ICM, or similar software.
• Support and lead engineering planning studies focused on flood mitigation and the development of solutions to flooding problems.
• Support engineering design and plan production through the development of Drainage Impact Analysis studies.
• Perform GIS-based spatial analysis using ArcGIS or QGIS to support watershed modeling and floodplain studies.
• Coordinate with project teams to develop design solutions for stormwater conveyance systems, culverts, detention facilities, levees, and other water-related infrastructure.
• Participate in design meetings and interdisciplinary coordination to understand project goals and constraints.
• Conduct field investigations, site visits, and data collection as needed to support modeling and design.
• Assist with technical reports, model documentation, regulatory submittals, and agency coordination (FEMA, USACE, state and local agencies).
• Review work for completeness and accuracy prior to submission to Project Managers.
• Support proposal development, scope definition, and cost estimating as needed.

• Bachelor’s or Master’s degree in Civil Engineering, Hydrology, or a related field.
• Minimum of 4 years of experience in water resources engineering , with exposure to both design and H&H modeling .
• Experience with hydrologic and hydraulic modeling software such as HEC-RAS (1D/2D), TUFLOW, XPSWMM, InfoWorks ICM, SWMM, or similar .
• Experience with ArcGIS or QGIS preferred.
• Programming experience (Python, MATLAB) for data analysis or automation is beneficial but not required.
• Strong analytical, organizational, and communication skills.

• Professional Engineer (P.E.) license required (or ability to obtain within 6 months).
• Ability to obtain licensure in additional states as required.
• Valid driver’s license for occasional field work.

Not only does HR Green provide you with a place to grow, thrive, and enjoy your work, but we are also dedicated to delivering a comprehensive and multi-faceted benefits package.
