Controls Engineer (EP-DT-FS-2025-267-GRAE)

Your responsibilities

As a Control Engineer in the detector cooling team, you will play a key role in the installation and commissioning of critical CO2 detector cooling control systems for ATLAS and CMS Phase II upgrade. These systems are PLC based with deported input/output and connected to a centralised SCADA system. Field equipment are using refrigeration instrumentation and actuators following industrial standards. The team integrates multidisciplinary expertise such as mechanical engineers, fluidics experts and control engineers. You will have the opportunity to extend your knowledge about cooling and control systems within our section.

Key responsibilities:

• Participate in the deployment and commissioning of the CO2 detector cooling control systems, with a focus on the CO2 distribution manifolds distribution in the proximity of detectors present in ATLAS and CMS during LHC Long Shutdown 3 (LS3).
• Develop and program PLC and SCADA systems using the CERN UNICOS CPC 6 framework.
• Draft and validate functional analysis documents to guide system behaviour, and safety logic.
• Prepare test plans and documentation to ensure systems meet operational, and performance requirements.
• Collaborate with multidisciplinary teams across CERN to ensure seamless integration of control systems.
• Lead on-site commissioning activities and provide follow-up on system updates and interventions (FSUs).
• Update electrical schematics following commissioning results.

Your profile

Experience:

• Experience in electrical and control system design, including component selection and electrical schematics (E-plan knowledge is a plus).
• Initial experience in commissioning, with troubleshooting and fault-finding curiosity.

Skills:

• Knowledgeable in PLC programming.
• Ready to learn process instrumentation and low-temperature system requirement.
• Team-oriented and comfortable in international environments.

Desirable skills:

• Familiar with Schneider PLCs and the CERN UNICOS framework.
• Knowledgeable about Python programming.
• Experienced in PID tuning.

Language skills:

• Spoken and written English or French, with a commitment to learn the basics of the other language.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Electrical Engineering or Automation (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.
