Job Overview:
The position of Electrical Engineer in the Fluidic Systems Section at CERN involves engaging with complex fluidic systems that are crucial for particle physics detectors. The successful candidate will be responsible for the commissioning, operation, and maintenance of CO2 cooling systems, which are essential for the High-Luminosity Large Hadron Collider (HL-LHC) experiments. This role requires a blend of technical expertise and problem-solving skills, as the engineer will participate in the installation and testing phases of these systems, ensuring they meet the demanding requirements of cutting-edge scientific research. The position offers a unique opportunity to contribute to significant advancements in particle physics while working in a collaborative and innovative environment.

Duties and Responsibilities:
As an Electrical Engineer in the Fluidic Systems Section, the candidate will undertake a variety of responsibilities, including:

• Participating in the installation, testing, and commissioning of CO2 cooling systems in both underground and surface facilities associated with the ATLAS and CMS experiments.
• Engaging in the maintenance and operational duties of the CO2 cooling systems, which includes being on standby duty service within the EP-DT-FS section.
• Conducting functional analysis and contributing to the definition and optimization of control software for the cooling systems.
• Supporting the optimization of the performance of CO2 cooling systems to ensure they operate efficiently and effectively under experimental conditions.
• Collaborating with multidisciplinary teams to troubleshoot and resolve issues related to the cooling systems and their integration with particle detectors.

Required Qualifications:
Candidates must possess a Master's degree or equivalent relevant experience in Electrical Engineering or a related field. Additionally, the following qualifications are essential:

• Demonstrated experience in PLC-based system programming and I/O commissioning, including troubleshooting and fault finding.
• Proven experience in electrical schematic design and verification, with familiarity in using EPLAN software considered an advantage.
• A solid understanding of the CO2 detector cooling process and experience with CO2 refrigeration instrumentation, particularly in low-temperature operations.
• Proficiency in Schneider and Siemens PLC programming environments, with pre-existing knowledge of the CERN UNICOS framework being a plus.
• Technical competencies in the installation, operation, and maintenance of industrial data-acquisition, monitoring, and control systems, as well as advanced controls.

Educational Background:
The educational background required for this position includes a Master's degree in Electrical Engineering or a closely related field. Candidates with equivalent professional experience in relevant areas may also be considered. A strong foundation in electrical engineering principles, particularly as they relate to control systems and fluidic technologies, is essential for success in this role.

Experience:
The ideal candidate should have substantial experience in the field of electrical engineering, particularly in areas related to PLC programming, system commissioning, and troubleshooting. Experience in the design and verification of electrical schematics is crucial, as is familiarity with CO2 cooling systems and their operational requirements. Candidates should demonstrate a history of working in complex technical environments, ideally within research or industrial settings that involve advanced control systems and instrumentation.

Languages:
Proficiency in spoken and written English is mandatory, and candidates should also have the ability to understand and communicate in French in professional contexts. This bilingual capability is essential for effective collaboration within the diverse international team at CERN.

Additional Notes:
This position is offered as a limited duration contract for three years, with the possibility of applying for an indefinite position subject to certain conditions. The working hours are set at 40 hours per week, and the role includes participation in regular standby duties, which may involve working nights, Sundays, and official holidays. Candidates must also be prepared for interventions in underground installations and possess a valid driving license. Due to the occupational health risks associated with this position, selected candidates will need to obtain medical clearance prior to the confirmation of their contract offer. The job grade for this position is classified as 6-7.
