Technical Engineer for Water Treatment Systems

The Engineering Department (EN) pushes forward the limits of technology so that physicists can carry out their research. Within the EN department, the Cooling and Ventilation (EN-CV) group is responsible for the design, the construction, the operation and the maintenance of the cooling and ventilation plants for large energy physics accelerators, experiments and technical facilities. The EN-CV group pursues sustainable cooling and ventilation systems enhancing energy savings and recovery.

You will join the Methods, Store and Electrical Section (CES), which oversees the operation and maintenance of water treatment systems, as well as the development of maintenance procedures, implementation of computerised maintenance management (CMMS), documentation management, spare parts store management and electrical works.

Are you a qualified and proactive and specialised in industrial water treatment systems, ready to contribute to a unique working environment at the heart of one of the world’s most complex scientific installations?

In this role, you will contribute to the analysis, optimisation and development of water treatment systems used for cooling and ventilation installations. You will ensure system performance, reliability and compliance with environmental and safety requirements, while supporting operation and maintenance activities.

Your responsibilities

• Study, design and validate the performance of new water treatment installations or upgrade of existing water treatment installations.
• Contribute to the water treatment contract management, produce technical specification and all the documents for the tendering procedure for the renewal of the contract.
• Lead technical investigations and root cause analysis for complex or recurring issues affecting water treatment systems.
• Plan, coordinate and oversee preventive and corrective maintenance activities (by using the CMMS system), defining appropriate strategies and ensuring alignment with operational needs.
• Monitor system performance and follow up on activities, ensuring reporting on progress, schedule and costs.
• Technically coordinate contractors’ activities for maintenance and installation work, ensuring compliance with contractual clauses, technical standards and safety requirements.
• Ensure that technical documentation is complete, structured and up to date, in line with quality standards.

Your profile

• Demonstrated experience in the operation, maintenance and optimisation of water treatment systems, including demineralised water production.
• Proven experience in water treatment of cooling circuits (cooling towers or closed circuits), including water chemistry aspects.
• Experience in the technical coordination of external contractors and activities.
• Experience in the use of CMMS tools.
• Experience in low-voltage electrical systems.
• Experience in analysing and troubleshooting technical systems would be an asset.
• Experience in contract management, would be an asset.
• Bachelor's degree or equivalent relevant experience in the field of Chemical Engineering, Process Engineering, Environmental Engineering or a related field.
