About The Position

Commonwealth Engineers, Inc. is seeking an accomplished water/wastewater process engineer to provide technical leadership for municipal drinking water and wastewater treatment projects and operational problem-solving. The role is intended for an engineer who understands treatment-process design and performance, biological and chemical systems, hydraulics, process controls, and the practical application of regulatory requirements to treatment facility design and operation. The successful candidate will combine strong process fundamentals with practical plant experience and sound engineering judgment, serving as a technical resource to clients, plant operators, and project teams in evaluating alternatives, resolving treatment challenges, and developing practical, reliable, and operable facilities. The position may also serve as a technical lead and, as appropriate, project manager for treatment-focused projects. It includes providing technical leadership through design, construction, commissioning, performance testing, startup, and optimization; performing senior-level quality reviews; and mentoring engineers and technical staff.

Requirements

  • B.S. in Civil Engineering or a similar discipline.
  • Registered as a Professional Engineer (P.E.); must be able to obtain reciprocity in Indiana or Kentucky if necessary.
  • Minimum 10 years of progressively responsible municipal water/wastewater engineering, technical, and management experience.
  • Strong technical knowledge of drinking water and/or wastewater treatment processes.
  • Working knowledge of applicable federal and state regulations, permitting requirements, and industry design standards.
  • Strong technical leadership and engineering judgment, with the ability to mentor engineers and technical staff.
  • Excellent written and verbal communication skills.
  • Ability to manage multiple assignments, work independently and in a team environment, and maintain a high standard of quality and organization.

Nice To Haves

  • Practical experience with treatment plant operations, troubleshooting, startup, and process optimization.

Responsibilities

  • Lead process engineering for municipal drinking water and wastewater treatment projects from planning and feasibility through design, bidding, construction, startup, and optimization.
  • Develop and evaluate treatment alternatives using process chemistry, microbiology, hydraulics, process controls, treatment objectives, regulatory requirements, reliability, operability, and life-cycle considerations.
  • Prepare and review design criteria, process calculations, process flow diagrams, hydraulic profiles, equipment sizing, process control narratives, design reports, technical specifications, opinions of probable construction cost, and contract documents.
  • Assess existing facilities and identify root causes of treatment, capacity, reliability, hydraulic, operational, and compliance problems through data review, field observation, operator interviews, sampling strategies, and process testing.
  • Evaluate and design hydraulic control, flow measurement, and flow-distribution systems needed for effective treatment-process performance.
  • Coordinate process requirements with civil, structural, mechanical, electrical, instrumentation, and controls disciplines to develop integrated, reliable, maintainable, and operable treatment facilities.
  • Provide technical leadership during construction, commissioning, performance testing, and startup; review submittals, respond to RFIs, support field decisions, troubleshoot process and hydraulic issues, and assist with process optimization.
