Magellium (Artal Group), with its 300 employees, is an independent company specialized in remote sensing from satellite and drone sensors with applications in Earth observation systems, cartography, and geointelligence. The company fosters expertise in space technologies, software development, signal processing, and geomatics, positioning itself as a key player in these fields.
As part of its Earth observation activities (earthobservation.magellium.com), Magellium plays a key role in major programs led by European space and operational agencies. The company The company is actively involved in satellite observation projects and scientific studies requiring expertise in remote sensing, measurement physics, atmospheric corrections, and geophysical parameter retrieval algorithms.
Magellium's work covers a broad range of applications, including low- and high-resolution optical imaging, imaging radiometers, spectro-imagers, and atmospheric sounders. This expertise supports space agencies such as CNES, ESA, and EUMETSAT, as well as projects focused on the interpretation and application of spatial data, including Copernicus services. Activities include performance assessments, sensitivity analyses, sensor calibration, and the fusion of data from multiple satellite missions.
Magellium is also involved in algorithmic studies and the prototyping of data processing solutions in scientific contexts, often in collaboration with research laboratories. The goal is to develop operational solutions for space mission ground segments and services based on space data exploitation. These activities demand both high scientific rigor and strict adherence to methodologies aligned with space industry standards.
This role within the "Earth Observation" unit involves leading and executing studies and projects focused on measurement physics — specifically in radiative transfer, atmospheric correction, atmospheric parameter inversion, and in-flight radiometric calibration — applied to multispectral and hyperspectral sensors.
Key responsibilities include :
Conducting scientific studies and prototyping solutions
Analyzing and defining methods and algorithms, and designing scientific processing chains
Utilizing and mastering tools and models, such as inverse models and radiative transfer models
Preparing technical documentation, including reports, specifications, manuals, and scientific publications
