Job Overview:
The position of Mechanical Engineer for Cryogenic Cooling Systems at CERN involves engaging in the development of a cryogenic cooling loop for superconducting systems, which includes magnets and current leads. The role requires participation in the design and operation of cryogenic cooling systems that can operate at variable temperatures, ensuring that the superconducting systems meet the necessary cooling requirements. The engineer will be responsible for optimizing thermal interfaces at the magnet and current leads level and executing experiments from both the cryogenic and superconducting system perspectives. Additionally, this role includes supervisory responsibilities, indicating a leadership component where the engineer will guide and oversee team activities.

Duties and Responsibilities:
The duties and responsibilities of this position include designing and operating cryogenic cooling systems with variable temperatures, assisting in the design of superconducting systems to meet cryogenic cooling requirements, and optimizing thermal interfaces at the magnet and current leads level. The engineer will execute experiments related to cryogenic and superconducting systems, ensuring that all designs are reliable and effective. Furthermore, the role involves organizing and executing experimental campaigns using dedicated data acquisition systems, preparing reliable designs of cryogenic and mechanical components, and conducting data analysis for the characterization of cryogenic cooling systems and their components. The engineer will also be expected to supervise team members and ensure that all project goals are met efficiently and effectively.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Mechanical Engineering or a related field. They should have either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. Additionally, candidates must not have previously held a CERN fellow or graduate contract. Experience with mechanical CAD software (such as CATIA or similar) and FEM software for mechanical and thermal analysis (like ANSYS or COMSOL) is essential. Proven capability in organizing and executing experimental campaigns using dedicated DAQ systems is also required.

Educational Background:
The educational background required for this position includes a Master's degree in Mechanical Engineering or a related field, or a PhD in a relevant discipline. The educational qualifications should be complemented by practical experience in the field, as outlined in the required qualifications section.

Experience:
The level of experience needed for this position includes 2 to 6 years of post-graduation professional experience for candidates with a Master's degree, or up to 3 years of post-graduation professional experience for those with a PhD. This experience should be relevant to the design and operation of cryogenic cooling systems and superconducting systems, as well as the use of mechanical CAD and FEM software.

Languages:
The mandatory language for this position is English, with proficiency in spoken and written form. Additionally, candidates should have a commitment to learn the basics of French, which is considered a good to have language for this role.

Additional Notes:
This position has 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 May 1, 202

• Candidates must be aware that this role involves exposure to electromagnetic fields under certain conditions, and they must obtain medical clearance before a contract offer can be confirmed.
