Switzerland doesn't have nearly as many underwater drilling rigs as the North Sea. And while there are a few professional divers in the Military as well as various Police (and possibly Firebrigades) forces I believe that such positions are reserved to Swiss citizens.
I'd try companies like Transocean, who are specializing in underwater explorations. They are based in Switzerland, but have activities worldwide.
