GNC Engineer [M/F]

About Exotrail 🚀

Space has never been so strategic, nor so contested. Tomorrow, space conquest will no longer be won just by putting objects into orbit, but by giving them a second life up there, by learning to guide them, reposition them, and extend their journey, with agility and precision.

Since 2017, we have been designing and operating the service fleet that commercial operators, institutions, and militaries rely on.

From high-performance propulsion systems (spaceware™) for small satellites to multi-mission and multi-orbit orbital transfer vehicles (spacevan™), we deploy, operate, and maintain in service the space infrastructure that private, public, and defense actors depend on to complete their telecommunications, Earth observation, or exploration missions, faster, further, and longer.

In a few years, we have gone from a handful of convinced engineers to a team of more than 200 Exotrailers, spread between Massy and Toulouse.

More than 75 million euros raised from prestigious venture capital funds and public actors allow us today to accelerate our mission: making space more sustainable.
