It's good that your being optimistic about it, really it is.

But I know of an american guy in Zhuhai with an engineering background, very smart,fluent in Chinese, and all he got was odd jobs installing a lift somewhere, but mostly he ended up teaching kindergarten and working on his own restaurant (which he ended up leasing out to chinese,because it was too much hassle) and running his own small training centre. Not meaning to burst your bubble but English teaching is what most laowais do over in China, with some exceptions like if you have been sent over by your company from the US/EU, then that is totally different.

What I am saying is...don't rock up and just expect to land a great gig because you look smart and got engineering background/qualifications, it doesn't work that way and I don't want you to be disappointed. As me and the OP said, most chinese engineers work on contracts O/S.

Still, good luck with it all man. Hope it all pans out.

Cheers and colds,
