I think you are right to worry. But it does rather depend how senior you are. You won't get much for 15k but would find something especially if you are prepared for a bit of travel (say, 30-40 mins) to get to work. But it is great experience and a fantastic place to live; will look good on the CV in the future too so you might think of it as an investment.
PS - that was 52HKD wasn't it?
