Don't have an exact figure, but SEA is very willing to pay. Meaning it's usually competitive rates. However the big problem would lie in the culture. Majority of Sea/Shopee/Garena's workforce are Chinese, so communications within the company is usually in Mandarin, which may pose a problem for many Singaporeans (sad to say this). In addition, it has a workaholic culture so many people stays late at night to complete projects. I'm not from Sea, but these are observations from many real life accounts of my network who has worked under Sea.
