About The Position

RETTEW is seeking an experienced Stormwater Management Engineer to bring specialized stormwater expertise to our growing Land Development practice. This role offers the opportunity to make stormwater a meaningful part of your career, focusing on solving complex drainage challenges, developing stormwater management strategies, navigating permitting requirements, and ensuring technically sound solutions work on real sites. You will support projects ranging from redevelopment sites to complex, multiphase developments exceeding 100 acres, working alongside a multidisciplinary team. Your work will directly influence how projects manage water, meet regulatory requirements, protect surrounding infrastructure and resources, and move successfully from concept through permitting and construction.

Hands-on experience performing hydrologic and hydraulic calculations and stormwater analyses.
Experience developing stormwater management or drainage designs for civil/site-development projects.
Working knowledge of grading, erosion and sediment control, utilities, permitting, and land development plans.
Experience preparing engineering calculations, reports, plans, and permit-support documentation.
Experience with stormwater modeling or water-resources engineering software.
Strong written and verbal communication skills and ability to collaborate across multidisciplinary project teams.
Valid driver's license and ability to travel to project, client, or agency locations as needed.
