Experimental Physicist; EP-DI--LD

Company Description

At CERN, the European Organisation for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter – fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact and provides insights into the fundamental laws of nature.

You will be part of the Experimental Physics (EP) Department, which carries out basic research. This Department aims at providing a stimulating scientific atmosphere and remains an important reference centre for the European physics community.

• Contribute to particle physics experiment projects at CERN.
• Participate in the design and development of experiments and detectors.
• Support the operation and performance of detector systems.
• Analyse experimental data and contribute to physics results.
• Collaborate with international teams and document results.

• PhD or equivalent relevant experience in the field of Physics or a related field.

• Towards the beginning of your career, with some years of post‑doctoral experience in experimental particle physics.
• Experience in data analysis and online/offline software.
• Demonstrated competence in detector hardware and experimental instrumentation.

• Knowledge and application of electromagnetic radiation propagation and interaction with matter.
• Physics analysis and experimental particle physics.
• Particle detectors and interaction of particles with matter.

• Learning and sharing knowledge: staying up‑to‑date with developments in your field and readily absorbing new information.
• Building relationships: relating well to all people regardless of category/level within the Organisation.
• Working in the interest of the Organisation: actively promoting safety and encouraging others to do the same; respecting safety rules and procedures.
