Application Deadline: 29 July 2026 23:59 CET/CEST

Publication: External Only

Type of Appointment: Intern

Directorate: Human and Robotic Exploration

Workplace: Porz-Wahn, DE

Location
EAC, Porz-Wahn, Germany

Our team and mission
The Space Medicine Team (HRE-HM) within the directorate of Human and Robotic Exploration directorate, is mandated to care for ESA Astronaut’s health and wellbeing during their entire career. In execution of this task, SMT performs numerous medical tests and evaluations to monitor Astronauts’ health that are collected into ESA Astronaut Medical Database (AMD).
SMT is responsible for maintaining, assuring the quality of, and further developing the AMD. Before the AMD was introduced, medical data were stored in a SQL Server database. Some of these records have already been transferred to the AMD, but the extent of the transfer is still unclear. This internship aims to support that transition by analysing the existing SQL database, creating a diagram of the relationships between tables, defining a secure transfer strategy to move data to the AMD without duplication, and documenting and helping implement that strategy.

During this internship, your mission will be to:

• analyse the SQL database and create a diagram showing the relationships between the existing tables;
• define a strategy for securely transferring data to the AMD while preventing duplicates;
• document the data transfer strategy and support its implementation.

Additionally, the Space Medicine Team has been looking into integrating AI solutions developed in house to gain more knowledge from medical record stored in the databases. With the support of the AI Team, you will be implementing a local search engine and fine tune it with the requirements of the Space Medicine Team.
