About The Role
We are seeking to appoint 2 x Commissioning Engineers to join us on a critical infrastructure project on an initial 12-month Fixed Term Contract.

This is a hands-on, site-based role requiring teamwork and expert problem-solving to ensure reliable water quality for a municipal client.
Key Responsibilities
* Commissioning Planning: Develop and implement detailed commissioning plans, test procedures, and schedules for plant systems (e.g., screens, pumps, chemical dosing, clarifiers, centrifuges / dewatering equipment).
* System Testing & Troubleshooting: Conduct functional performance tests (FAT/SAT), troubleshoot electrical and mechanical faults, and optimize the equipment & process.
* Quality & Compliance: Verify that installations align with P&IDs and design documents; ensure all activities meet environmental and regulatory standards.
* SCADA & Automation Integration: Collaborate with automation teams to test and refine SCADA/PLC control logic and instrumentation.
* Conduct plant operation during test periods
* Handover & Training: Assist in the preparation of comprehensive handover packages, including O&M manuals and performance reports; train client personnel on plant operations.
* Safety Leadership: Enforce strict health and safety protocols on-site, including Lock Out Tag Out (LOTO) and Permit to Work systems.
