Job Description

Join the Geodetic Metrology group at CERN, where you will take part in the metrology and alignment of a wide variety of components that are used in particle physics experiments! You will use state-of-the art surveying tools and software to achieve the sub-millimetre accuracy necessary to meet our goals. You will primarily contribute to the modernization of AWAKE, the pioneering plasma wakefield acceleration experiment, as well as to various alignment activities across the injector complexes and the Large Hadron Collider.

Your responsibilities

Participate in the design, development, and qualification of high-precision alignment system concepts, working in close collaboration with equipment groups; Coordinate survey activities, including network measurements, installation tasks, and alignment processes, from the preparation and supervision of interventions to their execution; Carry out, and supervise, the geometrical measurements at all stages of the production of the components from assembly to installation in situ using standard geodetic 3D techniques as well as laser tracker techniques, Be responsible for the data processing, comprising advanced stochastic analysis, creation of documentation and presentation of the results, Contribute actively to the R&D activities of the group related to alignment monitoring systems as well as participating in the development and maintenance of in-house surveying software applications, Perform the technical supervision of students and contractors.

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.
