About The Position

Parsons is seeking a highly experienced Principal Drainage Project Engineer to help establish and grow a dedicated drainage practice supporting the Tennessee Department of Transportation (TDOT) and transportation infrastructure clients throughout Tennessee and North America. This is a high-impact opportunity for a technical leader who can combine advanced drainage and hydraulic engineering expertise with client development, project delivery, and team leadership. The successful candidate will play a central role in building Parsons’ Tennessee drainage capabilities and will be positioned for advancement into a regional drainage practice lead role as the business continues to grow. In this role, you will serve as a technical leader for drainage design and hydraulic and hydrologic modeling on roadway and highway projects supporting TDOT and other transportation clients. You will contribute to the development of next-generation drainage design software, digital workflows, and technical standards within Parsons’ engineering community. You will be responsible for engineering drainage designs, hydraulic and hydrologic systems modeling, plan production, construction details, erosion and sedimentation control drawings, quantity calculations, and technical documentation. You will also review and validate engineering analyses, calculations, plans, specifications, and reports to ensure technical accuracy, quality, and compliance with project requirements. As Parsons builds its Tennessee drainage practice, you will help define service offerings, establish client relationships, identify project opportunities, support pursuits, mentor staff, and develop the technical and operational foundation for a growing regional practice. This role will require the selected candidate to be located in Tennessee and available to report to a Tennessee Parsons office as needed.
