Job Description

The Drainage Engineer will be responsible for the design, analysis, and documentation of storm water management systems, grading, and hydrologic / hydraulic components for residential, commercial, and municipal development projects. This role requires practical experience with drainage design software, a strong understanding of civil site design principles, and the ability to work both independently and collaboratively with engineering and CAD teams.

Job Functions and Responsibilities

• Prepare / review drainage design calculations, hydrology studies, and storm water management reports.
• Lead hydrologic & hydraulic studies using HEC-HMS, HEC-RAS, PC-SWMM, SRH-2D, etc.
• Develop / seal drainage reports, FEMA LOMR / MT-2 submittals, and drainage design plans.
• Perform watershed-scale flood risk analysis, inundation mapping, and storm water conveyance / detention design.
• Oversee junior engineers / EITs and provide structured technical mentorship.
• Support and / or lead grant funding efforts — including FEMA BRIC, CDBG-MIT, GLO, and flood bond initiatives.
