Avionics Hardware Architect (M/F)

About Exotrail

Space is becoming more strategic and competitive than ever. Tomorrow’s space leaders will not simply launch satellites into orbit, they will be able to move them, reposition them, extend their lifetime, and maximize their performance in space.

Since 2017, Exotrail has been developing and operating cutting-edge in-space mobility solutions for commercial, institutional, and defense customers. From our high-performance propulsion system spaceware™ to our orbital transfer vehicle spacevan™ , we enable satellites to go farther, stay operational longer, and achieve more.

Today, more than 200 Exotrailers across Massy and Toulouse are working together to make space operations more efficient and sustainable.

Backed by over €75 million in funding , we are pursuing a clear mission:

Making space a sustainable frontier for future generations.
