Extia Engineering's head office, this is where it all began! Let's keep writing history together.

Paris (head office)

Extia Engineering Mediterranean now has 70 employees, working mainly in Aix-en-Provence, Marseille, Pierrelatte and Toulon. Under the southern sun, we support our clients in the nuclear, petrochemical, naval, defence, rail, public works and telecommunications sectors. The little extra? Our design offices are also able to support our customers on fixed-price projects.

Our Grenoble agency was founded in 2015 on the "First who, then what" principle. At the time, Elodie was a Business Engineer in Lyon, so she moved to Grenoble with Extia in her suitcase. 

The Grenoble agency is known for its friendly atmosphere, but also for its expertise in the Energy & Process and Telecommunications sectors.

In November 2013, for the first time ever, Extia crossed the border and opened its first international branch: Extia Belgium! Today, 50 Extians operate in the industrial sector, mainly in the Brussels metropolitan area.
