Personally earning around S$100K per annum after about 6 years in the software industry. Know of a few engineering directors making about $150K to $180K per annum.

Kind of still doing engineering work, but was told that if I want to move up, I will have to move to a more management role.

If you're an local engineering student, you'd probably heard of this: when you start out, having engineering skills will get you up the ladder, but the higher you go, the more other skills come into play and it become less important how good an engineer you're.
