Jobs in GM

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.

Survey Technician (BE-GM-HPA-2026-243-GRAE)

What you’ll do:

Join CERN’s Geodetic Metrology Group and contribute to the metrology and alignment of components used in particle physics experiments. Your main focus will be the Full Remote Alignment System (FRAS), which uses a network of high-precision sensors and electromechanical actuators to monitor and remotely adjust accelerator components with micrometric precision.

Your responsibilities:

  • Supporting the procurement of FRAS mechanical and electromechanical components, including quality assurance and acceptance activities.
  • Assembling and testing FRAS components, initially in the workshop and subsequently in the LHC tunnel.
  • Preparing assembly, installation and validation documentation, including reports and procedure updates.
  • Taking part in the commissioning of the mechanical and electromechanical equipment, from individual components through to the complete FRAS installation.
