09.10.2025 Data Preprocessing Engineer for the LISA Space Mission M/F at LTE Paris In this project, we will develop new methods to reduce various noises in the LISA data efficiently in order to detect gravitational waves and to extract scientific results for various types of sources. These methods will then be implemented in a LISA data preprocessing pipeline. This position is devoted either to a researcher or to a software engineer. Strong skills in software development, data analysis, and numerical calculations are required. In addition, knowledge of the LISA mission and of its instruments will be favoured. Read more
