What you are saying makes me really sad. I live in Paris and I just graduated (CS). I am currently working as a java developer in a large company, the job is incredibly boring and I feel like I am not learning anything. Interesting jobs seems out of reach of a junior developer. I don't think Station F is going to improve things much. I am now thinking about moving somewhere else to find a better job.
There are good places ; if you aren't happy, move. Just don't pick a contractor job, and make sure you don't pick a job where people just expect you to move dirt around.
There are good places in Paris but they can be counted on your fingers. That's not enough jobs even if we only consider the population of 3lite 10x developers.
Change job and relocate, even if temporarily! Devs jobs are plenty, and you should take advantage of it while it's still the case. Working abroad for instance is a good way to get out of your comfort zone and keep on learning.
I know that feeling. Big companies are a scam. The good thing is: there is a lot of start-ups in Paris, many of them with open positions.
It's not that hard to find a place to work in Paris, it's hard for employers to find good candidates. I've spent most of the year looking for developers at Streamroot [1] and we struggled to have applicants. We hired 5 persons in the first 6 month of the year and still have a lot of open positions.
