Transportation Engineer -Hydraulics

With general direction, leads and develops transportation-related engineering designs of moderate to high complexity for highway, roadway, and other infrastructure projects to meet client requirements.

This role offers the opportunity to support a wide variety of transportation design projects across the country while serving as a technical leader in drainage, hydraulics, hydrology, and stormwater management.

• Lead the planning, analysis, and design of drainage, hydraulic, hydrologic, and stormwater management systems for transportation infrastructure projects.
• Develop and oversee large-scale transportation projects from preliminary engineering through final design, ensuring compliance with client objectives, project schedules, budgets, and quality standards.
• Prepare and review Erosion and Sediment Control Plans, National Pollutant Discharge Elimination System (NPDES) permit submissions, drainage reports, hydraulic studies, and stormwater management documentation.
• Perform and oversee hydraulic and hydrologic modeling using industry-standard software, including HEC-RAS, GeoHEC-RAS, HEC-HMS, WinTR-55, HydroCAD, and Pond Pack.
• Utilize advanced computer-assisted design and drafting (CADD) 3D and 4D software and practices in support of transportation projects.
• Review engineering designs and deliverables for compliance with federal, state, and local regulations, as well as firm standards and quality requirements.
• Sign and seal engineering documents and provide final design approvals, as required.
• Conduct site reviews, field investigations, construction inspections, and engineering studies to verify design assumptions and project requirements.
• Update design criteria and project requirements based on regulatory changes, site conditions, and client needs.
• Collaborate with multidisciplinary project teams, clients, agencies, and stakeholders throughout the project lifecycle.
• Support business development efforts by contributing to proposals, reviewing technical approaches, participating in interviews, and assisting in responses to Requests for Proposals (RFPs).
• Meet with existing and prospective clients to understand project needs and build long-term relationships.
• Contribute to the firm’s technical knowledge management initiatives through white papers, technical documentation, presentations, and publication of technical papers.
• Represent the firm at industry conferences, professional organizations, and technical events to enhance the visibility of the firm’s services and expertise.
• Perform other duties as assigned.

• Provide technical leadership, guidance, and quality oversight to engineering and design staff.
• Mentor, train, and develop junior engineers and designers, helping to expand the firm’s technical bench strength and future leadership pipeline.
• Lead project tasks and manage design staff from preliminary engineering through final design delivery.
• Foster professional growth through coaching, knowledge sharing, and hands‑on project development opportunities.
• May supervise and direct the work of junior engineers and technical staff.
