At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world's largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles.
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. It employs over 2,500 staff members and collaborates with thousands of scientists from around the globe. CERN's mission is to probe the fundamental structure of the universe, using the world's largest and most complex scientific instruments to study the basic constituents of matter. The organization operates in multiple countries and has a diverse workforce, which is central to its success.

Job Overview:
The position involves working within the CERN Experimental Physics department, specifically focusing on the R&D program for advanced silicon pixel detectors. The successful candidate will engage in the development of monolithic pixel detectors for the DRD3 OCTOPUS project. This role requires the adaptation and further development of the Caribou data-acquisition system, as well as leading test-beam data-taking and analysis. The position emphasizes collaboration with the EP R&D team and international partners involved in the DRD3 project, highlighting the importance of teamwork and communication in achieving project goals.

Duties and Responsibilities:
The primary responsibilities of this role include conducting laboratory and test-beam data-taking campaigns for monolithic pixel sensors, analyzing test data, and developing, commissioning, and operating FPGA-based data acquisition systems. The candidate will be expected to report findings during project meetings and supervise students and visiting scientists who are working on the project. This position also involves working in radiation areas, which requires adherence to safety protocols and regulations.

Required Qualifications:
Candidates must have a professional background in Physics or Electronics Engineering, or a related field. They 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, applicants must not have previously held a CERN fellow or graduate contract.

Educational Background:
A Master's degree or PhD in Physics, Electronics Engineering, or a closely related field is required for this position. The educational background should provide a solid foundation in the principles of physics and engineering, particularly as they relate to experimental setups and data analysis.

Experience:
The ideal candidate should have experience in pixel-detector test-data taking with particle beams, radioactive sources, or laser-light injections. They should also have a proven track record in analyzing experimental results and developing or maintaining silicon-detector test setups. Experience with FPGA-based data acquisition systems is also essential for this role.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language. This bilingual requirement reflects CERN's diverse working environment and the need for effective communication among international teams.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The job is fully onsite, and the target start date is set for March 1, 202
  • The position involves work in radiation areas, which necessitates compliance with specific safety measures. The compensation package includes a monthly stipend ranging from 6287 to 6911 Swiss Francs (net of tax), comprehensive health coverage for the employee and their family, and various allowances depending on individual circumstances. Employees are entitled to 30 days of paid leave per year, and CERN offers both on-the-job and formal training opportunities, as well as in-house language courses.
