As a Junior 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 the High Intensity ECN3 (HI-ECN3) project and contribute to the efforts of the Geodetic Metrology team in the North Area.

Your responsibilities:

• Participate in the design, development and qualification of high-precision alignment system concepts, working in close collaboration with the interdisciplinary team of the HI-ECN3 project.
• Prepare and check the quality of inputs (theoretical beamline trajectories, installation drawing, component geometrical data).
• Carry out geometrical measurements of components or prototypes using standard 3D geodetic techniques, such as laser tracker systems, and provide technical support to the equipment owner.
• Conduct survey activities, including network measurements, installation tasks, and alignment processes, from the preparation to realisation of interventions.
• Perform data processing using a 3D least-squares adjustment application as well as preparing technical documentation and presenting results.
• Contribute to the group's research and development activities related to alignment monitoring systems (e.g. ATS800, robotic platforms, robotic tracing, Universal Alignment Platform), and participate in the development, testing and maintenance of in-house surveying software applications.

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 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.
• By the application deadline, you have a maximum of two years of professional experience since graduation in Geomatics, Industrial Metrology (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
• You have never had a CERN fellow or graduate contract before.
• Applicants without University degree are not eligible.
• Applicants with a PhD are not eligible.

Job closing date: 04.06.2026 at 23:59 CEST.

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Working hours: 40 hours per week

Job flexibility: Fully Onsite

Target start date: 01-September-2026

This position involves:

• Work in Radiation Areas.
• Interventions in underground installations.
• A valid driving licence.
• Work during nights, Sundays and official holidays, when required by the needs of the Organization.
