Description Junior Professional in Resilient and Secure Ground Operations Services. If selected for this position, you will report to the Head of the Mission Operations IT (MOI-IT) and Operations Control Centre (OCC) Section in the Ground Facilities Operations Division, Mission Operations Department, Directorate of Operations.
The unit is responsible for the coordination and end-to-end provision of services and facilities to all users of the mission operations infrastructure, which consists of the following elements that support routine spacecraft operations and launches:
- The Operations Control Centre deployed at ESOC and in the ESA network of ground stations, such as data centres, or dedicated and main control rooms;
