Spotlight on our talents

"Since 2016, ATEXIS has given me the chance to develop my professional career, starting with an operational administrative role to becoming Project Manager, with over 30 people under my responsibility. I'm delighted to be able to manage a very diverse team of maintenance engineers and to support them in their missions around the world. I've learnt a lot over the last few years and I'm still learning every day to keep improving our projects, thanks to the support of our team and the backing of our management. "
Daria Urracchi,
In Service Support Project manager

"After twenty years in the army, I decided to join the civilian sector and put my technical expertise in maintenance to good use. This transition was not without its challenges, but ATEXIS was able to support me with structured management and regular monitoring. As I'm currently on assignment with a leading defense company, I'm enjoying the fact that I'm always in contact with military personnel and that I can put my experience in the army to good use in a new environment.
