The European Space Agency maintains a world-leading Science Programme with missions in heliophysics, planetary science, astrophysics and fundamental physics. Its mission is to empower Europe to lead space science.
The Science Operations Department (SCI-S) within ESA’s Directorate of Science hosts the scientists and engineers that oversee the space missions from the study phase to the end of operations. It develops the science operation systems for the missions and operates the missions in space, as well as archiving and curating their data during operations and beyond. Its main objective is to maximise the scientific output of the missions for the benefit of humankind.
You will be assigned as Science Operations Scientist, initially for the Arrakihs mission under the direct responsibility of the Science Operations Development Manager for Arrakihs in the Science Operations Development Division.
Arrakihs is a “Fast” (F-class) mission in ESA’s Science Programme. Its primary objective is to image the halos of galaxies in our nearby Universe to unprecedented low surface brightness, providing crucial data to answer unsolved questions in cosmology and galaxy evolution. Arrakihs is targeted for launch in the early 2030s.
You will be responsible for various aspects of the definition, implementation and testing of science operations activities for the Arrakihs mission, working in close collaboration with the Project Scientist, the Archive Scientist and the Science Operations Centre (SOC) Team and interfacing with the Instrument Operations and Science Data Centre (IOSDC) Team from the Arrakihs mission consortium.
During the development phase of the mission, your tasks and responsibilities will include:
In addition to the above duties, you are expected to continue to carry out research and actively contribute to the scientific activities of the Department.
It is expected that the position will also involve support to other survey missions in development within the Division, for example the Ariel mission, which will study the atmosphere of exoplanets through spectroscopic observations during transits and eclipses.
Experience in defining, setting up and/or operating scientific experiments for astrophysics research either in space or ground-based facilities
Experience in coordinating internal/external stakeholders on scientific projects
Active researcher in a relevant field to the Arrakihs mission
Knowledge of scientific instruments performance and calibration specification and analysis
Result Orientation
Operational Efficiency
Fostering Cooperation
Relationship Management
Continuous Improvement
Forward Thinking
