Hydraulic Modeler

Cannon & Cannon, Inc. (An Ardurra Company) is seeking an experienced Hydraulic Modeler for offices in Knoxville, TN, Nashville, TN, and Bowling Green, KY.

The candidate will provide engineering support for hydraulic modeling of water and wastewater systems using industry-standard modeling software. Responsibilities include building, calibrating, and applying hydraulic models to evaluate existing system capacity, simulate operational conditions, and assess proposed system improvements. This role involves translating system data, operational controls, and infrastructure characteristics into accurate and defensible modeling outputs that support planning and design decisions, and providing technical leadership in evaluating system performance, identifying capacity constraints, and developing long-term improvement strategies.

• Identify, collect, process, and input hydraulic and infrastructure data required for model development.
• Utilize tools such as AutoCAD, ArcGIS Pro, Microsoft Excel, SCADA systems, and other data management platforms to support model development and analysis.
• Execute calibrations of water and/or wastewater models meeting AWWA M32 calibration standards.
• Coordinate with engineering staff to define and obtain additional field data required for calibration, including unidirectional flushing/hydrant testing and extended pressure monitoring.
• Troubleshoot model convergence and simulation issues, coordinating with internal and external IT resources as needed.
• Export and present model results in the form of graphs, tables, GIS shape files, and mapping exhibits.
• Compile technical memoranda and reports documenting model development, calibration, system evaluation, and recommended improvements.
• Utilize fundamental hydraulic principles independent of modeling software to validate model inputs and results.
• Lead, assist, or compile necessary documents for kickoff, progress, and closeout meetings.

• BS in Civil, Environmental, Mechanical, or Computer Engineering.
• 5–7 years of engineering experience.

• Strong background in hydraulic modeling of water and/or wastewater systems.
• Proficiency with AutoCAD, GIS platforms (e.g., ArcGIS Pro), Microsoft Excel, and data analysis/statistics.
• Experience supporting public‑sector utility projects (water, wastewater, and/or reuse systems).
• Working knowledge of hydraulic behavior and modeling of pumping stations, lift stations, and system controls.
• Understanding of conveyance infrastructure including pipelines, control valves, pressure‑reducing stations, and metering facilities, and their impact on system hydraulics.
• Ability to evaluate system performance metrics including pressure, headloss, flow distribution, and operational reliability within complex systems.
• Experience incorporating facility‑specific operational characteristics into models to support planning, design, and operational decision‑making.

• Experience in water and sewer utility operation, maintenance, or construction.
• Experience authoring, or contributing to engineering technical memoranda and reports utilizing modeling.
• Proficient in hydraulic modeling software including Info Water Pro, Info Works ICM, WaterGEMs, SewerGEMs, or Aquanuity.
• M.S. or Ph.D. in Water Resources Engineering, with minimal years of experience.
• Licensed Professional Engineer.
