Drainage Engineer

STV is seeking a Drainage Engineer to support transportation infrastructure projects in our Austin, Texas office. This role is ideal for a drainage professional with 6 to 12 years of experience who is ready to expand technical design capabilities, contribute to complex infrastructure projects, and grow within a collaborative engineering team.

In this position, you will contribute to high-profile drainage analysis and design work, typically within the framework of transportation projects, while gradually taking on more ownership, mentoring others, and building the experience needed to move into a Design Task Lead role.

This position offers the opportunity to contribute to impactful infrastructure projects supporting TxDOT, toll authorities, local counties, and municipal agencies while building hands-on experience in drainage, stormwater management, hydrologic and hydraulic analysis, and regulatory coordination.

Why STV

At STV, you will join a nationally recognized engineering and infrastructure firm known for technical excellence and collaboration. This is a chance to join a growing Texas team where your voice, ideas, and technical judgment will matter while being surrounded by teammates who are committed to doing good work and helping each other grow. We invest in professional development, mentorship, and meaningful project work that strengthens communities.

You will have the opportunity to:

• Contribute to high-impact transportation infrastructure projects
• Grow your technical skills in drainage, stormwater, and H&H design and analysis
• Work alongside experienced engineers and project leaders
• Gain exposure to public-sector clients and regulatory agencies
• Build a long-term career path within a collaborative, multidisciplinary team

What You’ll Do

• Support drainage engineering design for transportation infrastructure projects, including roadway, highway, bridge, and rail improvements.
• Prepare stormwater management design, drainage design, culvert calculations, hydraulic structure design, Best Management Practices (BMPs), Low Impact Development (LID) features, and erosion and sediment control plans under the guidance of senior engineers.
• Perform hydrology and hydraulic analyses to support design decisions, permitting, and regulatory compliance.
• Assist with stormwater permitting, erosion and sediment control approvals, and environmental regulatory coordination.
• Prepare technical reports, drainage reports, stormwater documentation, design documentation, specifications, and engineer’s cost estimates with attention to accuracy, organization, and quality.
• Coordinate with roadway, structural, rail, and environmental teams to support integrated project delivery.
• Participate in internal design reviews and incorporate feedback from senior technical staff.
• Support quality reviews and QA/QC efforts by checking calculations, reports, plans, and permit documentation for completeness and consistency.
• Attend project meetings with clients, subconsultants, and regulatory agencies as part of the project team.
• Required Qualifications
• Bachelor’s degree in Civil Engineering, Environmental Engineering, or a related field.
• Professional Engineer (P.E.) license in Texas.
• 6 to 12 years of experience in drainage design, preferably supporting transportation infrastructure projects.
• Working knowledge of hydrology and hydraulic analysis, stormwater management design, drainage systems, culvert design, erosion and sediment control, Best Management Practices (BMPs), and Low Impact Development (LID) strategies. Experience with Edwards Aquifer Rules compliance is preferred.
• Demonstrated expertise in hydrology and hydraulic analysis using some of the following software packages: OpenRoads Designer Drainage and Utilities (DU), HEC-HMS, HEC-RAS, HY-8, StormCAD, and SWMM tools.
• Experience with MicroStation, OpenRoads Designer and ArcGIS .
• Strong written and verbal communication skills, including the ability to prepare clear technical reports and support high-quality engineering deliverables in multidisciplinary teams.
