Human-sized expertise

Created in 1989, Mediane Systeme has become a reference among engineering and consulting companies for our expertise with our clients, both large accounts and SMEs.  But where does our name come from ? 

In mathematics, the median divides a set into two equal halves, it is the middle of the set.

It is this concept of a happy medium that identifies us at Mediane, wee are professional but accessible. We are technical, but we don't forget the human side. We are serious, but we like to laugh.

For more than 30 years, we have been supporting our customers in the study, design and development of their products throught the wealth of expertise of our staff. 

Joining Mediane means joining the best of both worlds.

Business Manager

I am passionate about my job and the related human and technical issues. I have the chance to share this passion with the employees of my team. Mediane offers a framework that promotes this emulation under the impetus of the equally passionate Management! At Mediane Systeme, as Stendhal would say: The vocation is to have your passion as your job.

Recruitment Officer

In my job, sharing is an essential component. The sharing of expertise and technique is obvious, but at Mediane I also feel a sharing of human values, benevolent contacts, all through exchanges and events (evenings, outings ...).

Project Manager

Who said innovation was easy? With more than thirty years of existence, Mediane Systeme could be content to purr. However, I see a real desire to move forward and explore emerging technologies through new projects and in particular the MédianeLab cell. Of course, we are not the GAFAM, but innovation is far from lagging behind here.
