As a Survey Engineer you will join the Geodetic Metrology group at CERN, where you will take part in the metrology and alignment of a wide variety of components used in the particle accelerators. You will be using state-of-the-art surveying tools and software to achieve the sub-millimetre accuracy necessary to achieve our goals. This position offers a unique opportunity to collaborate on two major projects and contribute to the efforts of the Geodetic Metrology team in the North Area. The SPS (Super Proton Synchrotron) complex is being prepared for a significant upgrade through the North Area Consolidation (NA-CONS) and the TCC2 renovation project. As part of this renovation, you will be in charge of the dismantling of the existing beamlines will be dismantled and the installation of the new beamlines, scheduled in 2028/2029.

Your responsibilities

• Perform project follow-up: participation in coordination meetings, schedule review and collaboration with interdisciplinary teams.
• Prepare and check the quality of inputs (theoretical beamline trajectories, installation drawing, component geometrical data).
• Carry out and supervise all geometrical measurements at every stage, from assembly to on-site installation, using standard 3D geodetic techniques such as laser tracker techniques.
• Coordinate and take part in survey activities, including network measurements, installation tasks, and alignment processes, from the preparation and supervision of interventions to their execution.
• Be responsible for data processing using a 3D least-squares adjustment application, including advanced stochastic analysis, as well as preparing technical documentation and presenting results.
• Define and implement a strategy for the tracing of the new beamlines and services.
• Actively contribute to the group's research and development activities related to alignment monitoring systems (e.g. ATS800, robotic platforms, Universal Alignment Platform), and participate in the development, testing and maintenance of in-house surveying software applications.
• Supervise external contractors and students on technical topic.
• This role includes team supervision responsibilities.

Your profile

• Experience in the domain of high precision geodetic or industrial metrology including the instruments and the methods used in high accuracy metrology.
• Initial experience in coordination, planning, reporting and quality assurance aspects and supervision would be a plus.

Skills

• Knowledge and application of high accuracy survey methods and tools: laser tracker, digital and optical levels.
• Use of survey instruments as total stations and 3D laser scanning.
• Knowledge and practice of standard adjustment software: theories, concepts and algorithms related to the least square adjustment.
• Knowledge and application of data acquisition and data processing software (i.e., Python, Matlab, Spatial Analyser).
• Organisation, planning and control including supervision of work.
• Spoken and written English or French, with a commitment to learn the other language.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Geomatics, Industrial Metrology (or a related field) and have either:
  • a Master's degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.
