Position Overview

This role is focused on commissioning and startup of complex wastewater treatment process systems, not building systems. We are seeking professionals with direct experience in plant operations, system startups, and process integration across mechanical, electrical, and controls systems. Candidates should be comfortable working in active treatment facilities and engaging directly with operators, contractors, and engineers to deliver fully functional systems.

This is a field-based, hybrid role that integrates commissioning with construction oversight. In addition to supporting system startup, the position will contribute to installation verification, issue resolution, and turnover to operations. The objective is to ensure that systems are not only constructed correctly but perform reliably under real operating conditions.

For experienced commissioning professionals, this role offers the opportunity to work directly with owner representatives and plant operators on large, complex facilities, influencing system performance from installation through startup and turnover.

Responsibilities:

  • Support commissioning planning, system readiness, and startup for wastewater treatment process systems
  • Participate in functional testing and system verification across process, mechanical, electrical, and controls scopes
  • Coordinate with contractors, integrators, and operations staff during startup and system turnover
  • Provide field-based oversight of mechanical and electrical installations, including verification of compliance with plans and specifications
  • Identify and resolve system-level issues affecting performance, reliability, or operability
  • Support integration of process equipment with controls and SCADA systems
  • Assist with turnover documentation, punchlist resolution, and closeout activities
  • Engage with owner representatives and plant operators to confirm system performance and readiness.
