Elite Talent Hub are currently working with a well-established Irish engineering contractor specialising in water and wastewater infrastructure on a Commissioning Process Engineer appointment. This is a hands-on, site-facing role supporting the commissioning and optimisation of treatment plants across multiple projects nationwide.
The position suits someone who enjoys being close to the process — from raw influent through to treated water performance — and who wants exposure to full life-cycle commissioning, optimisation, client sign-off and continuous improvement rather than desk-based design only.
Key Responsibilities
* Support the commissioning, start-up and optimisation of water and wastewater treatment processes across live projects.
* Prepare and execute process commissioning test documentation in collaboration with project and design teams.
* Carry out jar testing, on-site sampling and laboratory analysis to determine optimum chemical dosing and process setpoints.
* Set initial PLC/HMI/SCADA process parameters and provide increased-care support post handover of flows.
* Monitor plant performance, alarms and trends, making and documenting process adjustments to meet compliance and performance targets.
* Compile commissioning, validation and performance reports for client submission and sign-off.
* Support troubleshooting, fault-finding and optimisation of existing treatment processes, including sludge treatment systems.
* Work closely with site teams and clients to ensure a collaborative, solutions-driven commissioning phase.
Key Skills
* Degree-qualified (Level 7 minimum) in Chemical, Environmental, Water/Wastewater Engineering or similar.
* 3+ years' experience in a process commissioning or operations role within water or wastewater treatment.
* Strong understanding of water and wastewater treatment processes, including clarification, filtration and chemical treatment.
* Hands-on experience with sampling, on-site laboratory testing and process optimisation.
* Familiarity with PLC/SCADA-driven treatment systems and process data analysis.
* Strong communication skills and confidence dealing directly with clients during commissioning and handover.
* Full driving licence and flexibility to travel to sites nationwide.
