Cooling and Ventilation Engineer - Switzerland

What you'll do: Within the CERN Engineering department (EN), the Cooling and Ventilation (EN-CV) group is responsible for the design, the building, 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 saving and recovery.

You will join the Project Section (EN-CV-PJ), which is in charge of coordination and management of cooling and ventilation projects for installation of new systems, upgrade of existing systems and consolidation of old systems both for CERN accelerators and experiments. The section is responsible for entire project cycles, starting from collecting user requirements to the final commissioning of cooling and ventilation systems.

Your responsibilities: - Pursue and define user requirements from main stakeholders. - Perform feasibility studies and detailed designs of industrial cooling and HVAC systems, including sizing and cost estimates for the proposed solutions. - Write up technical reports and notes. - Draw up technical specifications and all relevant documents, follow up the tendering process up to the adjudication of future contracts. - Follow up and regularly report on the project's progress. - Ensure technical coordination and supervision of contractors. - Monitor cost and schedule up to the commissioning and formal acceptance of the systems. - Support operation teams in the troubleshooting and process improvement of existing plants. - Actively contribute to the development and improvement of the internal procedures, technical prescriptions, and standardisation of the technical solutions.

Your profile: - Demonstrated experience in the design, construction and testing of industrial cooling systems including experience in selecting related equipment and instrumentation. - Initial experience in the design, construction and testing of HVAC installations and their related hydraulic components. - Proven experience in contract management. - Demonstrated experience in project management. - Master's Degree or equivalent relevant experience in the field of Mechanical Engineering or a related field. - Certification in project management (PMP/PMI) would be an asset.

Your skills: - Design and construction of cooling water systems: (cooling tower, demineralised and chilled water) and networks including test of plants and their associated equipment. - Design and construction of HVAC plants and networks: including test of plant and associated equipment. - Water cooling process design and analysis: as well as HVAC process. - Project management. - Contract management. - Has a structured and organised approach towards work; is able to set priorities and plan tasks with results in mind. - Ensures that information, procedures and decisions are appropriately documented. - Readily absorbs new techniques and working practices; proposes new or improved ways of working. - Works well autonomously; takes on activities and tasks without prompting. - Understands when teamwork is required to achieve the best results; includes others accordingly and shares information. - Spoken and written English, with a commitment to learn French.
