Graduate with some experience looking for work

[njay]

Hi just looking for a bit of advice, I graduate as a chemical engineer in 2012 in Melbourne. The job market is very tight at the moment in Australia and I managed to land a job as process engineer/ project management in Shanghai working for an Australian company. Due to visa issues I was only able to work 4 months and cant return back to the company.

I would love to work overseas and was wondering how difficult it would be get a job and visa in Singapore in process, project management or as sales engineer

Any advice would be appreciated.
