Cryogenic Cooling System Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries, fostering an environment of innovation and collaboration in scientific research. CERN's mission is to push the frontiers of science and technology, and it is committed to diversity and inclusion in its workforce.

Job Overview:
The Cryogenic Cooling System Engineer will be responsible for the development of a cryogenic cooling loop for a superconducting system, which includes the design and operation of cryogenic cooling systems with variable temperatures. The role involves assisting in the design of superconducting systems that meet the cooling requirements and optimizing thermal interfaces at the magnet and current leads level. The engineer will execute experiments from both the cryogenic and superconducting system perspectives and will also have team supervision responsibilities. This position is crucial for ensuring that the cooling systems function effectively within the superconducting applications, contributing to CERN's cutting-edge research in particle physics.

Duties and Responsibilities:

• Design and operate cryogenic cooling systems with variable temperatures to meet experimental requirements.
• Assist in the design of superconducting systems that align with the cooling specifications.
• Optimize thermal interfaces at the magnet and current leads level to enhance system performance.
• Execute experiments related to cryogenic and superconducting systems, ensuring accurate data collection and analysis.
• Supervise team members and coordinate efforts to achieve project goals.
• Prepare reliable designs of cryogenic and mechanical components for operational systems.
• Conduct data analysis for the characterization of cryogenic cooling systems and their components.
• Collaborate with multidisciplinary teams to address challenges and innovate solutions in cryogenic engineering.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State. A professional background in Mechanical Engineering or a related field is required. Candidates should possess 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.

Educational Background:
A Master's degree in Mechanical Engineering or a related field is required, with a preference for candidates who have relevant post-graduation experience. A PhD in a related discipline is also acceptable, provided the candidate has limited professional experience post-graduation.

Experience:
Candidates should have a minimum of 2 years of relevant professional experience for those with a Master's degree, or up to 3 years for those with a PhD. Experience using mechanical CAD software such as CATIA or similar, as well as familiarity with FEM software for mechanical and thermal analysis (e.g., ANSYS, COMSOL), is essential. Proven capability in organizing and executing experimental campaigns using dedicated DAQ systems is also required.

Languages:
Fluency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language being a plus. This bilingual requirement is essential for effective communication within the diverse CERN community.

Additional Notes:
The position is full-time, with a contract duration of 24 months, which may be extended up to a maximum of 36 months. The working hours are set at 40 hours per week. The target start date for this position is April 1, 202

• Candidates must obtain medical clearance due to occupational health risks associated with exposure to electromagnetic fields. The compensation includes a monthly stipend ranging from 6287 to 6911 Swiss Francs, tax-free, depending on the candidate's degree. Additional benefits include 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, and a relocation package.
