The Research Physicist position is situated within the Experimental Physics (EP) Department at CERN, which is dedicated to basic research in particle physics. The department aims to provide a stimulating scientific atmosphere and serves as a key reference center for the European physics community. The successful candidate will contribute to various particle physics experiment projects, participate in the design and development of experiments and detectors, support the operation and performance of detector systems, analyze experimental data, and collaborate with international teams to document results. This role is ideal for individuals who are at the beginning of their careers but have already demonstrated some post-doctoral experience in experimental particle physics, particularly in data analysis and software development.

Duties and Responsibilities:
The duties and responsibilities of the Research Physicist include:

• Contributing to particle physics experiment projects at CERN, ensuring that all aspects of the experiments are well-coordinated and executed.
• Participating in the design and development of experiments and detectors, which involves working closely with other physicists and engineers to create innovative solutions.
• Supporting the operation and performance of detector systems, which may include troubleshooting and optimizing existing systems to enhance their functionality.
• Analyzing experimental data and contributing to physics results, which requires a strong understanding of data analysis techniques and the ability to interpret complex data sets.
• Collaborating with international teams, sharing knowledge and results, and documenting findings in a clear and concise manner.
• Engaging in continuous learning and staying updated with developments in the field of experimental particle physics.

Required Qualifications:
Candidates must possess a PhD or equivalent relevant experience in Physics or a related field. They should have demonstrated competence in detector hardware and experimental instrumentation, as well as experience in data analysis and online/offline software. Technical competencies required include knowledge and application of electromagnetic radiation propagation and interaction with matter, physics analysis, and experimental particle physics. Additionally, candidates should be able to relate well to all people regardless of their category or level within the organization, actively promote safety, and respect safety rules and procedures.

Educational Background:
A PhD in Physics or a closely related field is required for this position. Candidates should have a strong academic background that includes extensive knowledge of experimental particle physics and related disciplines. This educational foundation is essential for understanding the complexities of the experiments and contributing effectively to the research conducted at CERN.

Experience:
The ideal candidate will be at the beginning of their career but should have already demonstrated some years of post-doctoral experience in experimental particle physics. This experience should include practical involvement in data analysis, software development, and hands-on work with detector hardware and experimental instrumentation. Candidates should be able to showcase their contributions to previous projects and their ability to work collaboratively in a research environment.

Languages:
Fluency in spoken and written English is mandatory, as it is the primary language of communication at CERN. Additionally, candidates should have a commitment to learning French, which is beneficial for integration into the local community and workplace.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position subject to certain conditions. The working hours are set at 40 hours per week, with hybrid job flexibility. The role may involve work in radiation areas, interventions in underground installations, and working during nights, Sundays, and official holidays as required by the organization's needs. The job grade is classified as 6-7, and the reference for this position is EP-DI-2026-29-LD. CERN offers a competitive salary that is tax-free, increasing with relevant experience, along with 30 days of paid leave per year, comprehensive health insurance, family allowances, and a relocation package depending on individual circumstances.
