Jetstar is looking for some drivers but you have to deposit some $ for bank guarantee and pay the company some $ for your type in toulouse, accomodation and airfare there and back to singapore. they do not advertise on their site but do give them a call.
tiger's website advertised for some driver's . write to them and a follow up call will be a good idea.
my honest opinion, a LCC is still a LCC. nothing special or extra. why not try some other major airlines and there are many airlines who are recruiting right now. I would not mention any figures here but for jetstar it depends which package you take besides securing a bank guarantee but figure wise for both i would say it's survivable in singapore. hope this helps and good luck
