What you'll do

The Engineering Department (EN) pushes the boundaries of technology to enable physicists to carry out world-class scientific research. Within the EN Department, the Cooling and Ventilation Group (EN-CV) is responsible for the design, construction, operation, and maintenance of the cooling and ventilation installations that support CERN’s accelerators, experimental facilities, and technical infrastructure.

Within EN-CV, the Controls Section (EN-CV-CL) is responsible for the specification, development, commissioning, operation, and maintenance of the industrial control systems used across all EN-CV installations.

The EN-CV control systems are based on industrial technologies, including Programmable Logic Controllers (PLCs), Supervisory Control and Data Acquisition (SCADA) systems, the UNICOS framework developed at CERN, automated code generation tools, and virtual commissioning methodologies. More than 650 PLCs are currently deployed and operated across EN-CV facilities, requiring a very high level of reliability, availability, and maintainability.

As a Controls Engineer, you will be involved in the full lifecycle of industrial control systems, from defining requirements and technical specifications to designing and implementing control solutions.
