Missions

Acquire and analyze Distributed Acoustic Sensing (DAS) data in various contexts

Activities

As part of the national D-LIGHT project (CNRS "Recherche à Risque" program), the DAS research group at the Géoazur laboratory (France) is recruiting an engineer to conduct DAS (Distributed Acoustic Sensing) data acquisition campaigns and ensure their analysis.

DAS technology leverages the high sensitivity of optical fibers to thermo-seismo-acoustic disturbances to transform standard telecommunications cables into high-density sensor networks. This innovative instrumental approach has already demonstrated its potential for monitoring various geophysical and geotechnical domains, including seismology, oceanography, bioacoustics, and infrastructure monitoring.

This position involves the planning and implementation of field campaigns, the processing and interpretation of DAS data, methodological development, as well as collaboration and communication within a multidisciplinary team focused on this technology (comprising at least 10 members) and the broader scientific community. Budgets will be available to successfully carry out the measurement campaigns.

Skills

The candidate should have a strong knowledge of wave physics and/or geophysics, as well as proficiency in signal acquisition and processing techniques. A strong interest in DAS technology and its applications is essential, along with the ability to handle and analyze large and complex datasets. Proficiency in data processing and analysis software (e.g., Matlab, Python, geophysical software) and solid computing skills (operating systems, networks) are required.

We are looking for a scientifically rigorous individual with strong organizational skills, autonomy, and the ability to take initiative. Excellent teamwork and interpersonal skills are essential. Adaptability, a willingness to learn, strong written and oral communication skills, as well as an enthusiasm for fieldwork and handling scientific instruments, are also indispensable.

Experience with DAS technology (acquisition, processing, analysis) or fiber optic metrology would be an asset. Additional valued skills include experience in developing data analysis scripts and tools, knowledge of geophysical data interpretation methods, and fieldwork experience in diverse environments. Fluency in English (reading, writing, speaking) and a record of scientific or technical publications would be additional advantages.

Work Context

The engineer will work at the Géoazur UMR7329 laboratory, located in Sophia-Antipolis (06). Géoazur is a multidisciplinary joint research unit composed of geophysicists, geologists, and astronomers, focusing on major scientific challenges: telluric hazards (seismic, gravitational, and tsunami-related) and associated risks, lithospheric dynamics and Earth imaging, as well as geodesy and metrology of the Earth and the nearby Universe. The laboratory comprises approximately 200 members, including researchers, faculty, engineers, and doctoral students.

The recruited individual will join a dynamic group of scientists specializing in DAS, with expertise in utilizing DAS data for various applications
