Hi!
I would not recommend to move to France without having fixed jobs ( not just CDD - contrat à durée déterminée - but CDI - contrat à durée indéterminée, and that after the trial period), unless you can benefit from some sort of " protection ".
You should at least register a a local ANPE ( Agence Nationale pour l'Emploi ) Umenmployment Office.
But for you, you should also register over the APEC
Apec.fr - Portail - Recrutement et offres d'emploi cadres
Then for you, best would be to contact directly all French and Foreign banks in France.
Yours,

PS.For you future wife, although such qualifications are desperatly needed, it hardly means that there are any jobs available, apart for temporary ( subventionned ) jobs for maximum one school year at mimimum wage level.
