Main responsibilities
- Your responsibilities
- Contribute to the conceptual design phase of the study, supporting the development and assessment of the collider design.
- Propose optimisations of the linear and nonlinear beam optics of the collider, including tune scans and multi-objective optimisation of the dynamic aperture, as well as optimising collider parameters to maximise machine performance and operational robustness.
- Perform particle tracking studies for the collider across its operating energy range, including the effects of beam-beam interactions, synchrotron radiation, and beam impedance.
- Investigate key accelerator physics challenges for the collider, drawing on experience from the FCC-ee study.
Key requirements
- Knowledge of beam dynamics in synchrotrons and/or storage rings.

Questions about this listing
What salary does CERN offer for this role?
CERN lists CHF 60'500 - 91'500 gross per year for this position in Genève. This is the salary published in the original listing (or, when the employer omits a figure, a realistic estimate for the role and sector) — the calculator on this site converts it to your actual net take-home once cross-border tax and social contributions are applied.
Is this a full-time role, and what type of contract does CERN offer?
This listing is a full-time position. The contract type shown here comes directly from the employer's original posting; always confirm exact hours, notice period and probation length with CERN during the application process, since these details can vary by role even within the same contract category.
Do I need a cross-border work permit for a role in Geneva?
EU/EFTA residents living in the border zone of the country adjoining Canton Geneva can apply for a G permit; the Swiss employer files it with that canton's migration office after the contract is signed. Border-zone rules and processing times vary by neighbouring country and canton, so confirm the specifics with Geneva's cantonal migration office or with HR during the application.
