Job Description
Your responsibilities
The SY-STI-TCD Section oversees the conceptual design, construction, operation, and maintenance of beam-intercepting devices across the CERN's accelerator complex. The beam intercepting devices are precision mechanical equipment working in harsh environments that must be very reliable to guarantee the operation of CERN accelerators.
Are you passionate about mechanical engineering and skilled at multitasking? Join us!
You will be part of a multidisciplinary team responsible for the design, assembly, installation, and maintenance of beam-intercepting devices. These systems play a critical role in the safe and efficient operation of CERN's accelerators.
In this role, you will oversee the cycling of LHC spare collimators to ensure their maximum availability and to detect potential issues in advance. You will also take part in the operation and maintenance of the LHC collimation system, including regular technical interventions and service activities.
Additionally, you will perform maintenance and installation of beam intercepting devices in the accelerator facilities and conduct on-line commissioning tests to ensure operational readiness. You will also provide mechanical support for activities within the accelerator complex and assist in the operation of the mechanical workshop.

At CERN, the European Organization 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. Find out more on http://home.cern.
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
