Civil Engineer IV – Water/Wastewater Treatment & Process

Primary Function

The Engineer IV acts as a staff specialist, providing advanced technical guidance for complex or unique engineering assignments. This role independently completes tasks or assigned portions of projects with minimal supervision and applies diversified, in-depth knowledge of civil and environmental engineering principles.

The incumbent is expected to independently make decisions on significant design, process, and constructability challenges, particularly related to municipal water and wastewater infrastructure.

The Water/Wastewater team in Oklahoma is an integral part of the design process for municipal infrastructure projects. This position serves as a technical leader on water and wastewater projects, supporting planning, design, permitting, and construction-phase services while ensuring compliance with applicable regulatory requirements and client standards.

Primary Duties

• Participate in the development of project design concepts, criteria, and process alternatives for municipal water treatment plants, wastewater treatment facilities, lift stations, force mains, transmission mains, and related infrastructure.
• Perform and oversee process engineering evaluations, including treatment technology selection, hydraulic and process modeling, capacity analysis, and lifecycle cost comparisons.
• Analyze complex design and process problems requiring the development of new or improved engineering techniques, procedures, or design standards.
• Make recommendations on project staffing, technical approach, and scope definition for water and wastewater projects.
• Provide technical review and guidance on plans, specifications, reports, calculations, and cost estimates.
• Consult with construction personnel regarding design constructability, sequencing, and operational considerations, particularly for active facilities and phased construction.
• Serve as technical lead or resident engineer during construction, reviewing contractor submittals, schedules, pay applications, and change orders for compliance with design intent and regulatory requirements.
• Monitor project progress for technical accuracy, quality assurance/quality control (QA/QC), schedule adherence, and budget compliance.
• Prepare and finalize planning documents, including preliminary engineering reports, facility plans, technical memoranda, and regulatory submittals.
• Provide technical input for proposals, scope development, and client presentations, engaging with project managers and business development teams.
• Represent assigned projects at client meetings, public meetings, and technical conferences.
• Plan, organize, and supervise design engineering activities for large, complex projects requiring integration of multiple disciplines (civil, structural, mechanical, electrical, and process) or multiple concurrent water/wastewater projects.
• Provide direction, mentoring, and technical oversight to Engineers I–IV, CADD designers, and other technical staff.

Education And Experience Requirements

• Bachelor’s degree in Civil, Environmental, or related Engineering discipline from an ABET-accredited program.
• Professional Engineer (PE) license required (Oklahoma or ability to obtain Oklahoma licensure by reciprocity).
• 5–8 years of progressively responsible engineering experience, with a significant portion dedicated to municipal water and wastewater projects, including:
• Water treatment facilities (groundwater and/or surface water)
• Wastewater treatment facilities and collection systems
• Lift stations, force mains, and pump station design
• Water distribution and wastewater conveyance systems
• Demonstrated experience with water and wastewater process engineering, including treatment unit processes, hydraulic profiles, pumping systems, and operational considerations.
• Working knowledge of state and federal regulatory requirements, including permitting and compliance considerations applicable to municipal water and wastewater infrastructure in Oklahoma.
• Proven proficiency with engineering software and design tools, including hydraulic and process modeling, and an understanding of system capabilities and limitations across diverse engineering assignments.
