• Conduct pressure and leak tests, ensuring the integrity and functionality of cooling systems.
• Design and manufacture small mechanical assemblies for prototype tests, contributing to the development of innovative cooling solutions.
• Engage in maintenance activities for water and CO2 cooling systems, including the upkeep of CO2 membrane pumps and the replacement of valves or filters.
• Collaborate with a multidisciplinary team of technicians, engineers, and other professionals to ensure the successful implementation of cooling systems.
• Maintain accurate documentation of all activities, including testing results, maintenance logs, and design modifications.
• Adhere to safety protocols and regulations, particularly when working in radiation areas and underground installations.
• Participate in training and development opportunities to enhance skills and knowledge related to cooling systems and mechanical engineering.

Required Qualifications:

• Nationality of a CERN Member or Associate Member State.
• A maximum of two years of professional experience since graduation in Mechanical Engineering, HVAC, or a related field.
• A Bachelor's or Master's degree in Mechanical Engineering or a closely related discipline.
• Strong interest in cooling systems and mechanics, with a demonstrated ability to collaborate effectively with others.
• Experience in design and manufacturing of small mechanical assemblies is highly desirable.
• Familiarity with CAD systems such as CATIA or equivalent is considered an advantage.
• Experience in maintenance and operation of cooling systems, particularly CO2 cooling systems, is beneficial.
• Knowledge of pipework manufacturing and joining techniques (welding, brazing) is a plus.
• Proficiency in spoken and written English or French, with a commitment to learn the basics of the other language.

Educational Background:
Candidates must possess either a Bachelor's or Master's degree in Mechanical Engineering, HVAC, or a related field. Applicants without a university degree are not eligible for this position, and those with a PhD are also not eligible. The educational background should provide a solid foundation in mechanical engineering principles, particularly as they relate to cooling systems and mechanical assemblies.

Experience:
The ideal candidate should have a maximum of two years of professional experience since graduation. This experience should be relevant to mechanical engineering, HVAC, or related fields, demonstrating a practical understanding of cooling systems and mechanical design. Candidates with extensive experience or those who have previously held a CERN fellow or graduate contract are not eligible for this position.

Languages:
Proficiency in spoken and written English or French is mandatory for this position. Candidates should be committed to learning the basics of the other language to facilitate effective communication within the diverse team at CERN. Knowledge of additional languages may be considered an advantage but is not required.

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

• The position involves working in radiation areas and may require interventions in underground installations. Candidates must reside in the immediate vicinity of CERN's installations and possess a valid driving license. Stand-by duty may be required, as well as work during nights, Sundays, and official holidays, depending on the organization's needs. The selected candidate must obtain medical clearance due to the occupational health risks associated with this position. The compensation includes a monthly stipend ranging from 5196 to 5716 Swiss Francs (net of tax), coverage by CERN's health scheme, and various allowances depending on individual circumstances.
