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.

Mechanical Engineer (BE-GM-FP-2026-31-GRAP)

What you will do:

As a Mechanical Engineer, you will join the multidisciplinary Future Projects team working on R&D for the alignment of Future Circular Collider (FCC) components. You will develop mechanical and mechatronic adjustment and support systems requiring high vibration stability and micrometric precision.

Your responsibilities:

  • Gathering of design requirements and preparation of functional specifications.
  • Designing mechanical support and alignment/adjustment solutions, including vibration and stability analysis in the frequency domain (modal response, transmissibility, and resonance evaluation). Perform "as-built" measurements of tunnels and buildings using the laser scanner technology.
  • Integration of the proposed solutions into accelerator integration models, including interface alignment with system-level constraints, along with cost estimation for the proposed solution. 
  • Follow-up, in close collaboration with other teams, of the manufacturing, assembling and qualification of prototypes.
  • Preparation and presentation of technical reports, calculations, and engineering notes. Perform the calibration, checking and testing of survey instrumentation and accessories.
  • This role includes team supervision responsibilities.

Geodesist (BE-GM-FP-2026-29-GRAP)

What you will do:

The Geodetic Metrology Group (BE-GM) provides metrology and alignment for accelerator components, beam lines, and experiments across CERN, including geodetic reference systems and gravity field modelling. The Future Projects section prepares technical foundations for upcoming facilities through studies, simulations, and prototyping.

Your responsibilities:

  • Compute and validate a state-of-the-art quasi-geoid model covering FCC area and Switzerland.
  • Explore and propose solutions for modelling equipotential surfaces inside tunnels.
  • Take part in field observation campaigns (gravity, GNSS, leveling, astro-geodetic) required to fill data gaps or to validate the computed models.
  • Develop a gravity field modelling software package by combining existing tools and new features developed for the project.
  • This role includes team supervision responsibilities.
