Senior Civil Engineer

Senior Civil Engineer

The Senior Civil Engineer is responsible for leading the planning, analysis, design, and production of complex civil engineering projects for the Office of the County Engineer's (OCE) in-house design program. This position applies advanced engineering judgment and technical expertise to deliver safe, accurate, cost-effective, constructible, and code-compliant infrastructure solutions.

With minimal supervision, the Senior Civil Engineer leads and performs civil design activities related to roadway and site development, grading, hydrology and hydraulics (H&H), stormwater management, drainage systems, utilities, and other public infrastructure improvements. Responsibilities include hydrologic and hydraulic modeling, drainage and stormwater calculations, storm sewer and culvert design, detention and conveyance analysis, grading and earthwork design, erosion and sediment control, and preparation of plans, specifications, estimates, and technical reports.

The position coordinates closely with project managers, engineers, surveyors, environmental professionals, other County departments, Precincts, consultants, regulatory agencies, and external stakeholders. Designs must comply with applicable OCE, Harris County Flood Control District (HCFCD), TxDOT, local Authority Having Jurisdiction (AHJ), environmental, and other applicable local, state, and federal requirements.

The Senior Civil Engineer is accountable for the technical quality and timely completion of assigned engineering tasks within established project scope, budget, and schedule.

Job Duties:

The Senior Civil Engineer's responsibilities include but are not limited to:

• Lead and perform planning, analysis, and detailed civil engineering design for drainage, stormwater, roadway, utility, site development, and other public infrastructure projects.
• Perform hydrologic and hydraulic analyses and modeling for storm sewer systems, culverts, channels, detention facilities, outfalls, and other drainage infrastructure.
• Develop construction plans, profiles, cross-sections, grading plans, drainage plans, details, 3D models, and other technical documents using appropriate CAD and civil engineering software.
• Prepare and review engineering calculations, drainage and H&H reports, design reports, technical memoranda, quantity estimates, cost estimates, specifications, and supporting documentation for project development, permitting, and construction.
• Perform grading design, cut-and-fill analysis, earthwork calculations and balancing, erosion and sediment control design, and stormwater pollution prevention planning as applicable.
• Review and interpret survey data, utility information, record drawings, geotechnical reports, drainage studies, environmental information, and other technical inputs required for design development.
• Review and check engineering designs, calculations, plans, and technical documents prepared by junior engineers, designers, consultants, and CAD technicians for accuracy, consistency, constructability, and compliance with applicable standards.
• Coordinate multidisciplinary design activities with project managers, surveyors, structural engineers, architects, geotechnical engineers, environmental staff, utility coordinators, consultants, contractors, regulatory agencies, and other internal and external stakeholders.
• Conduct and document field investigations and site visits to verify existing conditions, identify project constraints, evaluate drainage and infrastructure concerns, and support engineering recommendations.
• Prepare and support development of project specifications, bid documents, engineer's estimates, and other procurement and construction documents for capital improvement projects.
• Provide engineering support during construction, including review and response to Requests for Information (RFIs), submittals, design clarifications, field conditions, proposed design changes, and other construction-related issues.
• Ensure engineering work complies with applicable OCE and Harris County criteria, HCFCD requirements, TxDOT standards, local AHJ requirements, and applicable state and federal regulations and engineering practices.
• Serve as an internal OCE Subject Matter Expert (SME) for hydrology, hydraulics, drainage, and stormwater infrastructure and provide technical guidance in resolving drainage-related issues raised by OCE clients, including Harris County Precincts and other departments.
• Provide technical leadership, mentoring, and guidance to junior engineers, designers, CAD technicians, and other technical staff.
• Develop project scopes, schedules, technical approaches, resource requirements, and level-of-effort estimates for assigned projects and engineering tasks.
• Prepare and present project updates, engineering analyses, recommendations, and technical findings to management, project teams, County departments, Precinct representatives, regulatory agencies, and other stakeholders.
• Maintain proficiency in applicable engineering software, design standards, regulations, and emerging technologies and identify opportunities to improve design quality and efficiency.
• Support disaster response, emergency operations, and post-event infrastructure assessments as needed, including drainage, outfall, roadway, and other infrastructure-related incidents.
• Perform other duties as assigned.
