Job Description
Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With over 2,500 employees and thousands of scientists from around the globe, CERN operates in multiple countries and is dedicated to pushing the frontiers of science and technology. The organization is known for its groundbreaking work in particle physics and has a mission to uncover the fundamental structure of the universe. Diversity is a core value at CERN, and the organization fosters an inclusive environment where innovation and collaboration thrive.

Job Overview:
The position of Physicist Engineer for Radiation Environments and Effects is situated within the Radiation to Electronics (R2E) activities of CERN's Beam Matter Interaction Physics (BMP) section. The primary focus of this role is to study radiation environments and their impact on accelerator systems. The successful candidate will be part of the Monitoring and Calculation Working Group, where they will analyze radiation data to mitigate the exposure of electronic systems and enhance the availability of CERN's accelerators. This role requires a deep understanding of radiation-matter interactions and the ability to apply this knowledge to real-world scenarios in a high-energy physics environment. The candidate will also be responsible for characterizing radiation fields, assessing mitigation measures, and improving software tools for data processing and analysis.

Duties and Responsibilities:
The duties and responsibilities of the Physicist Engineer include:
  • Characterizing the radiation field at CERN accelerators, experimental areas, and irradiation facilities.
  • Analyzing data recorded in the CERN accelerator complex to assess radiation levels.
  • Evaluating the need for R2E mitigation measures to enhance the availability of CERN accelerators.
  • Consolidating and improving existing software tools for radiation level data processing and analysis.
  • Conducting analysis of radiation effects characterization and modeling aspects in electronic components, including implications on accelerator RHA guidelines.
  • Engaging in both experimental and simulation activities related to radiation effects.
  • Collaborating with a multidisciplinary team to ensure effective communication and problem-solving.

Required Qualifications:
Candidates must possess a professional background in Applied Physics, Electronics 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 be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Educational Background:
The educational background required for this position includes a Master's degree or PhD in Applied Physics, Electronics Engineering, or a closely related field. The educational qualifications should be complemented by relevant professional experience in the field of radiation-matter interaction physics and radiation level measurements.

Experience:
Candidates should have experience in the field of radiation-matter interaction physics and radiation level measurements. Familiarity with radiation effects on electronics, including modeling and testing aspects, is essential. Experience with data analysis software tools for applied physics, such as Python and SQL, is also required. Familiarity with Monte Carlo codes would be considered an advantage.

Languages:
The mandatory language for this position is English, with a strong emphasis on both spoken and written communication skills. Candidates are also expected to have a commitment to learning French, which is considered beneficial for the role.

Additional Notes:
This position is fully onsite and involves working in radiation areas and underground installations. The contract duration 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, and there may be requirements for stand-by duty, as well as work during nights, Sundays, and official holidays, depending on the needs of the organization. The compensation includes a monthly stipend ranging from 6372 to 7004 Swiss Francs, which is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, and a relocation package depending on individual circumstances.
