The one industry in France which always has a shortage is IT. It follows that someone from outside the European Union ,with exceptional skills in IT,beyond those of a typical French or EU citizen , may be permitted to work there.
France is probably the hardest country in the European Union for a non-EU citizen to get a work permit. Even American employees of multi-national corporations are usually only on 18 month visas there. For them to work longer, they need to be fully employed by the French subsidiary, be of high status in the company and on a high salary, to justify their presence to the French authorities.
You will need to be 18, anyway.
Of course, if you have substantial funds, the French welcome you as a foreign resident who buys a home there, but that's another matter.
