I wanted to ask if anyone has recommendations by which Airlines I have any chances if i am not a Singaporean/Permanent Resident?

Short resume: Currently and for the past 3,5 years I am working for Lufthansa German Airines. I pass all major requirements like hight, swimming and all medicals were fine.
Language wise i am a german native speaker, fluent in english, good basics in french an afrikaans and i just started to learn mandarin as well.
I checked out a few Airlines. SIA as an example only recruits S/PR or other asian passport holders. And i suppose an unsolicited application does not make sense by such a huge Airline.
Other Airlines which have singapore based crew are mostly LCC where I suppose they are not interested in applying/offering employment passes. Are they taking recruits with an LOC?
I know that chances to find employment in aviation based in SIN will be almost impossible under these circumstances but maybe somebody has some helpfull ideas....
thank you very much in advance
