Fibre Optics Sensor Engineer

Your responsibilities

You will join the Engineering Department (EN), which pushes back the limits of technology so that physicists can carry out their research. Specifically, you will join the Electrical Engineer Group.

Our Fibre Optics section is looking for a motivated engineer/physicist to join the team, which is responsible for the operation and maintenance of the Distributed Optical Fibre Radiation Sensor (DOFRS) systems at CERN.

You will be involved in the operation, maintenance, installation, qualification and calibration of this advanced radiation monitoring system.

Main activities:

• Carry out regular maintenance of both passive and active elements of the DOFRS systems.
• Supervise the correct operation of the systems during periods of data acquisition.
• Provide support for the installation of DOFRS systems across CERN facilities.
• Perform irradiation tests aiming at qualifying and calibrating of the radiation sensitive optical fibres used in the DOFRS.
• Prepare and follow-up the manufacturing of DOFRS sensing cables.
• Ensure complete and accurate documentation of the DOFRS-related activities and materials.
• Provide support to the development activities aimed at improving the monitoring of the DOFRS systems in operation and extending their sensing capabilities.

Close collaboration with the Systems Department (SY), specifically the Monitoring and Calculation Working Group (MCWG) at CERN:

• Act as an interface during CERN operational periods to ensure continuous and reliable system performance.
• Verify the quality of measurements provided by the DOFRS systems.
• Assist the MCWG in its activities within its radiation monitoring mandate.

Your profile

Skills:

• Knowledge or experience in optics and/or fibre optics.
• Interest in sensors, radiation sensing and innovative instrumentation would be beneficial.
• Strong practical skills and interest in hands-on field work and laboratory tasks.
• Strong interest and proficiency in developing scripts/software tools, particularly using languages such as Python. Experience with additional programming languages such as LabVIEW is advantageous.
• Detail-oriented and capable of maintaining thorough technical documentation.
• Good communication skills and a collaborative mindset.
• Spoken and written English, with a commitment to learn French.
