Hydrology & Hydraulics (H&H)

• Build, calibrate, and run HEC-HMS (event + continuous) models
• Develop HEC-RAS 1D/2D models for channels, floodplains, and structures
• Prepare profiles, inundation maps, and mitigation concepts
• Conduct pre/post development stormwater analysis (detention, retention, conveyance)
• Produce sealed calculations, plans, and design reports

Stormwater & Water Quality

• Develop / QA PCSWMM / EPA SWMM collection system models (separate & combined systems)
• Represent LID/GI and simulate continuous system performance
• Support MS4/NPDES compliance, SWMP elements
• Perform TMDL/WLA evaluations and BMP screening/selection
• Apply EFDC/EFDC+ (or equivalents) for watershed/receiving-water assessments

CFD & Hydraulic Structures

• Conduct CFD studies using OpenFOAM or Ansys Fluent/CFX
• Analyze spillways, stilling basins, dropshafts, outfalls, junctions, and energy dissipation
• Validate CFD models with HEC-RAS or physical data

Design, Documentation & Permitting

• Prepare stormwater management plans, drainage reports, erosion & sediment control plans
• Produce opinions of probable cost, bid documents, specifications
• Coordinate FEMA floodplain (CLOMR/LOMR) studies
• Collaborate across Civil 3D, GIS, geotechnical, survey, environmental, and construction teams

Project Management & Leadership

• Act as day-to-day technical lead
• Develop scopes, budgets, schedules, risk registers
• Mentor junior staff and support QA/QC
• Contribute to proposals and interviews

🎓 Qualifications

Required:

• B.S. in Civil/Environmental Engineering (M.S. preferred)

• 5–8+ years of stormwater/water-quality project experience
• Expertise in:
  PCSWMM/EPA SWMM
  HEC-HMS
  HEC-RAS 1D/2D
• Strong understanding of MS4/NPDES, TMDL/WLA processes, and BMP sizing
• Proficiency in ArcGIS/QGIS, AutoCAD Civil 3D
• Excellent technical writing and communication skills
• Working knowledge of Python and/or MATLAB for automation, QA/QC, and data processing

Preferred (Great to Have):

• Water-quality/watershed modeling: EFDC/EFDC+, SWAT
• CFD with OpenFOAM or Ansys (free-surface, VOF, turbulence modeling)
• CFD modeling (OpenFOAM, Ansys Fluent/CFX)
• Experience with 2D rain-on-grid workflows
• Familiarity with FEMA, USACE, and state DOT/DEP stormwater guidance
• Exposure to engineering DevOps (Git, reproducible workflows)
• Cloud computing awareness
