Who are we ?

Junior CentraleSupélec was born in 2017 from the merger of Junior Supélec Stratégie (J2S) and Junior Centrale-Etudes (JCE), two Junior-Enterprises famous for their technical skills and expertise. Indeed, these two entities won the prize for Best French Junior-Enterprise 4 times altogether (in 2000, 2010, 2014 and 2017), as well as the prize for Best European Junior-Enterprise in 2019, 2020 and 2021.

This merger, which was the biggest in the history of Junior Enterprises, has allowed JCS to assert itself since its creation as a professional and experienced JE. Thanks to top-level technical courses taught at CentraleSupélec in fields such as IT, energy or data analytics, JCS already carries out highly advanced projects for its clients.

Experienced consultants

Through its three offices in Paris, Rennes and Metz, JCS selects its consultants amongst over 4 200 engineering students, who will graduate from CentraleSupélec in the near future. They are carefully selected by our project managers on the basis of their technical skills and motivation, so as to ensure that your projects are carried out efficiently.

These consultants follow a very high-level curriculum in one of the best French engineering schools, which allows them to be at the cutting-edge of technology. Moreover, they benefit from CentraleSupélec and its teachers’ support and are given a privileged access to the labs or networks they might need to carry out a project.
