Hi. What qualifications do you currently have or expect to get?

I will have a french BAC with the speciality Mathematics and English

i need to know if it's enough or i need more qualification

Having spoken to our recruitment team they recommend looking at enic-naric.net to determine how your qualifications translate. I hope this gives you some guidance.
