Senior Drainage Engineer

Lead FDOT transportation drainage design and stormwater management on some of Florida’s most visible highway, roadway, interchange, and bridge projects. In this senior water resources engineering role you will own hydraulic analysis, drainage design, floodplain and stormwater modeling, pond siting, culvert and storm sewer design, and environmental resource permitting from concept through delivery. You will apply industry-standard tools including ICPR, HEC-RAS, Micro Station ORD Drainage, and GeoPAK Drainage to complex FDOT and local-agency drainage projects across Florida.

We are seeking a licensed P.E. with deep FDOT drainage engineering experience in transportation drainage, stormwater management, hydraulic and hydrologic (H&H) analysis, drainage permitting through SJRWMD, SFWMD, SWFWMD, NWFWMD, and FDEP, bridge hydraulics, pond siting analysis, and MS4 / stormwater compliance to serve as technical lead and grow our Florida Stormwater / Water Resources practice.

“We’re excited to hire a leader for our Stormwater/Water Resources practice to expand our capabilities and reinforce our reputation as an industry leader throughout Florida.” Steve Boylan, VP, Florida Business Sector Leader

• Partner with leadership on client development and Florida market growth, and represent GAI at industry events.

• Bachelor’s or master’s degree in civil engineering or a related discipline.
• Florida P.E. license, or the ability to obtain one by reciprocity.
• 10+ years of transportation drainage engineering experience, or equivalent depth.
• Demonstrated FDOT project delivery in Florida.
• Strong command of stormwater management, hydraulic analysis, drainage design, and transportation permitting.
• Proven ability to lead teams, build consensus, and make sound engineering and business decisions.
• Valid driver’s license.

• Urban and limited-access roadway drainage design; local government roadway, trail, and multimodal projects.
• ICPR, HEC-RAS, Micro Station ORD Drainage, and GeoPAK Drainage.
• Pond siting analysis and bridge hydraulic report preparation.
• Experience with FDOT Districts 1, 2, 3, 5, or the Turnpike Enterprise.

• An established pipeline. High-visibility FDOT highway, urban roadway, bridge, and trail work across Florida. Experience with Districts 1, 2, 3, 5, or the Turnpike Enterprise is preferred, not required.
• Real technical authority. You set the drainage approach on complex stormwater, hydraulic, and permitting work.
• A team to build. Mentor engineers and help shape the growth of GAI’s Florida Transportation practice.
• In-house support. Roadway, bridge, environmental, and planning colleagues one call away.
