• Archive final deliverable documents – reports, models, and associated tools.

• Experienced with public project delivery for water/wastewater/ recycled water.

• Strong understanding of how to conduct infrastructure modeling to include water pumping stations and sewer lift stations and the effects to system hydraulics and modeling outcomes.

• Strong understanding of how conveyance infrastructure such as pipelines, flow control facilities, turnouts, pressure‑reducing stations, metering stations, and related facilities effects system hydraulics and modeling outcomes.

• Ability to evaluate how these components influence pressures, headloss, flow distribution, and operational performance within complex water, wastewater, and recycled water systems.

• Experience and ability to integrate facility-specific characteristics into hydraulic models to support accurate planning, design, and operational decision‑making.

• Bachelor’s Degree in Civil, Environmental, or related Engineering from an ABET accredited university or equivalent. Equivalent modeling and master planning project experience with another STEM degree will be considered.

• 5-8 years of related experience in master planning tasks related to but not limited to: developing / confirming water demand factors and demand projections, developing / confirming sewer flow factors and flow projections, performing I/I analysis, business risk calculations, alternative analysis, cost estimations, alternatives scenario analysis, fire flow analysis etc.

• Experience with hydraulic modeling tools such as Autodesk modeling products including but not limited to InfoWater, InfoWater Pro, InfoSWMM, InfoSewer, Aquanuity or other equivalent software. Experience with other modeling tools will be considered.

• Experience with ArcGIS Pro and integration with Innovyze software.

• Excellent technical writing skills for use in development of master plans, studies, engineering reports, and related technical documents.

• Strong organizational, analytical, and problem-solving skills
