Job Overview:
The Control Systems Engineer position at CERN offers a unique opportunity to engage in the cutting-edge field of particle physics, specifically contributing to the Phase II upgrades for the ATLAS and CMS experiments. The role involves the deployment and commissioning of CO₂ detector cooling control systems, which are critical for the experiments. The successful candidate will leverage their technical expertise in automation and controls within a highly collaborative and international environment. This position is designed for individuals who are eager to apply their skills in a practical setting while working alongside multidisciplinary teams to ensure the seamless integration of control systems. The role also emphasizes the importance of safety and operational performance, requiring the preparation of test plans and documentation to meet these standards.

Duties and Responsibilities:
The duties and responsibilities of the Control Systems Engineer include participating in the deployment and commissioning of CO₂ detector cooling control systems, focusing on the Surface Storage subsystem. The engineer will develop and program PLC and SCADA systems using the CERN UNICOS CPC 6 framework. They will draft and validate functional analysis documents to guide system behavior and safety logic, ensuring that all systems meet operational and performance requirements. Additionally, the engineer will prepare test plans and documentation, collaborate with multidisciplinary teams across CERN, lead on-site commissioning activities, and provide follow-up on system updates and interventions (FSUs). This role requires a proactive approach to troubleshooting and fault-finding, as well as effective communication and teamwork skills.

Required Qualifications:
Candidates must possess experience in electrical and control system design, including component selection and electrical schematics, with knowledge of E-plan being a plus. Proficiency in PLC programming and I/O commissioning is essential, along with strong troubleshooting and fault-finding skills. Familiarity with Schneider PLCs and the CERN UNICOS framework is also required. The ideal candidate should have a good understanding of process instrumentation and low-temperature system requirements, and must be team-oriented and comfortable working in international environments. Proficiency in spoken and written English or French is mandatory, with a commitment to learn the other language.

Educational Background:
Applicants must hold either a Bachelor's or Master's degree in Automation and Robotics or a related field. It is important to note that applicants without a university degree are not eligible for this position, nor are those who hold a PhD. The educational background should be relevant to the technical demands of the role, ensuring that candidates have the necessary theoretical knowledge to succeed in practical applications.

Experience:
Candidates should have a maximum of two years of professional experience since graduation in the relevant field of Automation and Robotics. This experience should be applicable to the duties outlined in the job description, demonstrating the ability to engage effectively in the responsibilities of the Control Systems Engineer role.

Languages:
Proficiency in spoken and written English or French is mandatory for this position. Candidates are expected to have a commitment to learn the other language, which is essential for effective communication in the diverse and international environment at CERN.

Additional Notes:
The position is a full-time role with a contract duration of 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the target start date for the position is August 1, 202

• The role involves working in radiation areas and performing interventions in underground installations, which requires a valid driving license.
