Head of Production Assurance

Joan Miralles found his enthusiasm for technology at a young age through construction toys like Meccano and Lego. That is what pushed him to learn the “magic” behind aeronautics and aviation through gaining his bachelor degree at the Polytechnic University in Madrid. During his studies, he realised that space was far more interesting for him than aviation could ever be, so he decided to take courses in this direction. After college he decided that his bachelor degree was not enough, so he decided to pursue a master degree specialising in Aerospace Engineering at the FH University in Wiener Neustadt. His background in power systems for spacecrafts allowed him to take part in the student project PEGASUS, a satellite developed by the FHWN. For his master thesis, he went to the Institute of Space Systems at Stuttgart University, where he worked in the development of a test stand for MPD thrusters. This experience led him to Airbus Safran Launchers, now ArianeGroup, where he had the opportunity to work on the development of RF-Ion Thrusters. It was here that he first heard about the project that ENPULSION was carrying out, and chose to pursue a position on the team in early autumn 2017.
