Applied Physicist

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

• It is known for its groundbreaking work in the field of particle physics and is located at the border of France and Switzerland. 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 and is dedicated to pushing the frontiers of science and technology, fostering an environment of innovation and collaboration.

Job Overview:
The position involves working within the CERN Experimental Physics department, specifically focusing on research and development (R&D) for advanced silicon pixel detectors. The successful candidate will be responsible for integrating sensors and readout electronics into compact, lightweight detector hybrids. This role requires the development and testing of new methods for connecting these components, necessitating close collaboration with the R&D team and international partners. The position is crucial for advancing the technology used in future experiments, contributing to the scientific community's understanding of fundamental physics.

Duties and Responsibilities:
The duties include contributing to the development and validation of in-house hybridization processes utilizing advanced interconnect technologies such as conductive adhesives and gold studs. The candidate will also be responsible for producing functional hybrid assemblies in collaboration with various projects. Additionally, the role involves preparing and maintaining testing infrastructure for laboratory and test-beam measurements, conducting performance testing of advanced hybrid timing and tracking detectors, and performing reliability tests including thermal cycling and irradiations. The candidate will develop quality assurance (QA) and quality control (QC) procedures for yield measurement and failure classification, and will be responsible for analyzing test data, documenting findings, and publishing results. Furthermore, this role includes supervisory responsibilities over team members.

Required Qualifications:
Candidates must possess a strong background in silicon-detector technology, including device fabrication and testing, experiment design, and material characterization methods. Proficiency in analyzing test data is essential. The ideal candidate should have knowledge of silicon detectors, basic Python programming skills, and the ability to work effectively in multi-disciplinary teams. Strong presentation and documentation skills are also required, along with proficiency in spoken and written English or French, with a commitment to learn the basics of the other language.

Educational Background:
The position requires candidates to be nationals of a CERN Member or Associate Member State. Applicants must have a professional background in Physics or a related field, with either a Master's degree accompanied by 2 to 6 years of post-graduation professional experience, or a PhD with no more than 3 years of post-graduation professional experience. It is important that candidates have not previously held a CERN fellow or graduate contract.

Experience:
Candidates should have relevant professional experience in the field of physics or a closely related area, with a minimum of 2 years for those with a Master's degree, or up to 3 years for those with a PhD. This experience should include practical work related to silicon detectors and experimental physics, demonstrating the ability to contribute effectively to research and development projects.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language being a requirement. Knowledge of additional languages may be considered an asset but is not mandatory for this position.

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 candidates should be prepared to work in radiation areas and during nights, Sundays, and official holidays as required by the needs of the organization. The job reference is EP-DT-SD-2025-243-GRAP, and the field of work is Applied Physics. The position offers a monthly stipend ranging from 6372 to 7004 Swiss Francs, which is tax-free, along with 30 days of paid leave per year plus 2 weeks of annual closure. Candidates will also benefit from CERN's comprehensive health insurance scheme, family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
