Job Description

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

The Geodetic Metrology Group within the Beams Department (BE-GM) provides metrology and alignment for components installed in the accelerators, their beam transfer lines and physics experiments throughout the CERN complex.
The GM-ASG (Accelerator Surveying & Geodesy) section is responsible for the geodetic and metrology measurements as well as the alignment of the accelerator components and their associated beam transfer lines for the whole CERN site. Furthermore, the ASG section is in charge of the acquisition and processing of high accuracy point cloud data defined in the primary CERN reference frame (CCS).
The High-Luminosity Large Hadron Collider (HL-LHC) project aims to maximize the performance of the LHC, significantly enhancing its discovery potential beyond 2029. The goal is to increase the LHC’s integrated luminosity by a factor of ten compared to its original design. To achieve this, over one kilometer of the LHC will be upgraded during Long Shutdown 3 (LS3), starting in mid-2026. Advanced components, including cryo-magnets, collimators, crab cavities, and superconducting links, will be installed in the tunnel.
As a Survey Engineer in the Accelerator Surveying & Geodesy (ASG) section, you will be part of the team in charge of the metrology and the alignment of the HL-LHC accelerator components.
You will be using state-of-the-art surveying tools and software to achieve the sub-millimetre accuracy necessary to achieve our goals.

In this role you will:

• Perform HL-LHC metrology measurements at all stages of the assembly of accelerator components from manufacturing controls of mechanical parts to final transfer measurements using laser tracker technology.
• Ensure geometrical conformity as a key aspect of quality control throughout the production process.
• Carry out fiducialisation-process of defining the mechanical axes of components and transferring this information to external targets for precise alignment.
• Utilize Laser Tracker Instruments and Spatial Analyzer to perform high-precision measurements.
• Execute and supervise metrology tasks, including measurement operations, calculations, and documentation.
• Collaborate with a team of experts to build, inspect, and finalize next-generation accelerator components.
• Perform the alignment of various components throughout the CERN complex, ensure the maintenance of the related survey infrastructure and geodetic networks,
