Hydraulic Modeler

Responsibilities

• Develop, update, calibrate, and maintain water distribution and wastewater collection system models for planning, design, and operational evaluations.
• Perform scenario analyses such as system capacity and level-of-service evaluations; pipe and pump sizing; booster/pump station evaluations; and fire flow, pressure zone, storage, and water age/water quality screening (as applicable).
• Compile, review, and validate model input data from GIS, as‑builts, asset inventories, SCADA/telemetry, flow monitoring, and field testing.
• Use GIS (Esri ArcGIS/ArcGIS Pro) to prepare, spatially validate, and manage model datasets (e.g., networks, demands, basins, customer meters, assets).
• Apply data analysis methods to identify trends, data gaps, anomalies, and optimization opportunities; develop dashboards, tables, and clear visualizations for technical and non‑technical audiences.
• Prepare technical memoranda and report sections documenting assumptions, calibration, results, and recommended improvements.
• Coordinate with multi‑discipline teams to support master planning, design, permitting, and construction support activities.
• Participate in client meetings; communicate modeling approach and findings effectively.

• Bachelor’s degree in Civil Engineering, Environmental Engineering, Water Resources Engineering, or related discipline.
• Masters preferred but not required.
• EI (Engineer Intern) / EIT certification required (active and in good standing).
• Demonstrated experience with water and/or wastewater modeling software, such as:
• Working proficiency with Esri ArcGIS tools and geospatial datasets.
• Strong data analysis skills (advanced Excel; experience with Python/R and/or SQL is a plus).
• Strong technical writing and communication skills; ability to work independently and collaboratively on multiple concurrent assignments.
• Valid driver’s license and ability to travel locally as needed for field verification/support (project-dependent).

• Very good presentation, technical writing, and public speaking skills.
• Experience calibrating models using field data (e.g., flow tests, hydrant tests, pressure logging, flow monitoring).
• Familiarity with utility planning and operations (e.g., CIP support, asset management integration).
• Experience with model animation/visualization and presentation‑ready outputs.
• Experience with implementation of machine learning and/or AI methods to solve engineering problems.
• Participation in industry organizations is encouraged (e.g., AWWA, WEF, ASCE/EWRI, local utility associations); presenting or publishing is a plus.
• Progress toward PE licensure (or ability/intent to obtain PE within an established timeframe).
