Survey Engineer (BE-GM-HPA-2022-97-LD)

  • Geneva, Switzerland
  • Contract

Company Description

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

Job Description


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. You will design, qualify and install all the alignment solutions for the upgrade of CERN’s flagship accelerator, the Large Hadron Collider (LHC). Take part!


As a Survey Engineer, you will integrate a multi-disciplinary team in charge of the development, installation and commissioning of all alignment solutions requiring micrometric accuracy, with the implementation of continuous measurement and remote adjustment systems.

  • You will be in charge of the maintenance and consolidation of cutting-edge/high precision alignment sensors (i.e.hydrostatic Levelling Sensors, and Wire Positioning Sensors and Dimensional Offset Measurement Sensors) in the LHC.
  • You will be responsible for the integration, qualification, preparation, installation and commissioning of all the alignment sensors and their associated electro-mechanical systems for the upgrade of the LHC. This will include their qualification on dedicated test setups.
  • You will manage all the quality aspects related to these alignment systems, including asset management, documenting preparation and installation procedures, and producing intervention schedules.


Master's degree or PhD or equivalent relevant experience in the field of Surveying, Geomatics, Topography, Geodesy or a related field.


  • Proven experience in the domain of high precision measurements, including measurement preparation, configuration and analysis using least square algorithms.
  • Demonstrated experience in the coordination, planning, reporting and quality assurance aspects of project management.
  • Experience with the use of alignment sensors would be an asset.

Technical competencies:

  • Knowledge and application of high-precision survey methods and tools: laser tracker, optical and digital level
  • Organisation, planning and control
  • Knowledge and practice of standard compensation software: theories, concepts and algorithms related to the least square adjustment.
  • Design and use of micrometric alignment systems.
  • Knowledge and application of data acquisition and data processing software (Python, Matlab, SA). 

Behavioural competencies:

  • Communicating effectively: Listening actively to others and letting others speak. Utilising effective negotiation techniques to achieve long-term results acceptable to all parties involved.
  • Achieving results: Having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
  • Solving problems: Identifying, defining and assessing problems, taking action to address them. Assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely.
  • Working in teams: Contributing to promoting a positive atmosphere in the team through an optimistic and constructive attitude; addressing issues. Gaining trust and collaboration from others.
  • Working in the interest of the Organization: Behaving consistently with CERN's values and goals. Actively promoting safety and encouraging others to do the same; respecting safety rules and procedures.

Language skills:

Spoken and written English or French: ability to understand and speak the other language in professional contexts. Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in English.
