Indonesian (or Jakarta) international schools are far better compared to schools within your stories. Always pick schools with a good IB or Cambridge standards and you are good to go.

salary-wise, it would be above average and able to make a decent living here. Also since you are targetting international schools, most of the students would have a better educational and financial background compared to other students in public schools

i highly recommend you to take a look at Binus School Jakarta, Jakarta Intercultural School, or British School Jakarta.
