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.
Join the Geodetic Metrology group at CERN, where you will take part in the metrology and alignment of the wide variety of components that are used in particle accelerators and detectors. You will be using, developing or testing state-of-the art surveying tools and software to achieve the sub-millimetre accuracy necessary to achieve our goals. Take part!
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.
