Your responsibilities

Are you a Mechanical Engineer with a passion for challenging and exciting projects in the field of beam instrumentation for particle accelerators? Then seize the opportunity! Join the CERN Beam Instrumentation (BI) Group and be part of the team working on the study and development on the next generation of beam instrumentation across the whole accelerator chain.

The SY-BI-ML Section is in charge of the development, electro-mechanical design, construction, installation and maintenance of instrumentation created within the broader SY-BI Group.

The position will be focused on the failure analysis of edge-welded bellows, which are key and critical features of several equipment.

Your responsibilities will include:

• Studying the origin of the failure;
• Defining a consolidation plan for the upcoming years;
• Defining best practices for the design of new instruments.

You will be part of a multicultural diverse team working at the forefront of the scientific research, working in a very stimulating environment that will help you develop your skills in precision electro-mechanics design, simulation tools and research.

About us

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.
