Want to move to Singapore!

You should look at online job boards like jobsdb and jobstreet, but even better are connections - do you know anybody in your industry in Singapore? (If not, try Linkedin or similar.)
And, if you are serious, you should schedule an extended trip to Singapore (at least a month) and mention that in your applications - applicants who are abroad very rarely get interviews, so you need to be in the country to have a chance!

Thanks Beppi for your response. In case I do plan to come on an extended trip to Singapore, what kind of accommodations can I get in Singapore other than a hotel accommodation? Is it possible to rent out a place for a month in Singapore where I can stay and look out for interviews there?

Due to the shortage of space, it is not allowed to rent out residential property for periods under 6 months and to people not having a residence permit.
With a tourist visa (SVP), you are limited to hotels, hostels and serviced apartments (which start at S$60-80/night) - or staying with friends for free.
