The position is designed for individuals who are passionate about theoretical physics and wish to collaborate with leading researchers in a dynamic and innovative environment.

Duties and Responsibilities:
The primary duties and responsibilities of the Research Associate include conducting scientific work in theoretical particle physics or closely related fields. The candidate will be expected to follow and engage with current developments relevant to their area of research, interact with researchers and scientific groups within the CERN theoretical physics community, and contribute to scientific discussions and exchanges during their stay. Additionally, the associate will be responsible for maintaining close links with the international theoretical physics community and actively participating in collaborative research efforts.

Required Qualifications:
Candidates must hold an advanced academic background in theoretical particle physics or a closely related discipline. They should possess solid experience in research and/or teaching in theoretical physics and demonstrate active engagement in scientific work within their field of expertise. Strong analytical and theoretical reasoning skills are essential, along with the ability to engage in high-level scientific discussions and knowledge exchange. The ability to work effectively in an international and collaborative research environment is also a key requirement.

Educational Background:
A PhD or equivalent advanced degree in theoretical particle physics or a closely related field is required for this position. Candidates should have a strong foundation in theoretical physics principles and methodologies, as well as a demonstrated ability to conduct independent research.

Experience:
The ideal candidate should have a significant level of experience in research and/or teaching in theoretical physics. This includes a proven track record of scientific publications and contributions to the field, as well as experience collaborating with other researchers and participating in scientific discussions.

Languages:
Fluency in English is mandatory, as it is the primary language of communication at CERN. Proficiency in French is also beneficial and may enhance collaboration within the organization. Candidates should be able to communicate clearly in a scientific context in both languages.

Additional Notes:
The application deadline for this position is 31st March 2026 at 23:59 Geneva Time. The ideal start date for the position is 1st July 2026, with a contract duration of up to 6 months. The weekly working hours are set at 40, and the position is fully onsite at CERN. The job reference for this position is AGC-2026-1/CASS-TH. Global benefits include a subsistence allowance of 4384 Swiss Francs per month (tax-free), authorized absences, a family supplement depending on individual circumstances, and travel expenses to Geneva upon joining CERN. Candidates must remain employed by their home institute during their appointment at CERN, and their institute must be located in a CERN Member or Associate Member State (excluding France, Italy, Germany, and Great Britain). Additionally, applicants must be below the CERN retirement age by the application deadline.
