• Equivalent combination of education and experience.

Minimum Required Qualifications:

• Experience in the following areas:
  • Hydrologic watershed modeling (both continuous and event modeling).
  • Reservoir routing.
  • Demonstrated ability to calibrate hydrologic models and evaluate model performance.
  • Statistical analysis of hydrometeorological time series.
  • Collection, QA/QC, and interpretation of hydrologic data.
  • Technical documentation and report writing.
  • Experience working with hydrologic and meteorological GIS datasets.
  • Proficiency with open-source programming languages (Python, R, C#, VB.NET) for data management, transformation, QC, and statistical analysis.
  • Basic geospatial processing and mapping using ArcGIS or QGIS.
  • Proficiency with Microsoft Excel and familiarity with relational databases (SQL).
• To qualify, applicants must be legally authorized to work in the United States and should not require, now or in the future, sponsorship for employment visa status(e.g., H-1B visa status, etc.). 

Preferred Qualifications:

• Experience with hydrologic modeling tools such as HEC-HMS, SAC-SMA, or SEFM.
• Experience with snowmelt routines such as the UBC model and Snow-17.
• Familiarity with probabilistic or stochastic modeling concepts.
