There is a Knowledge Migrant Visa which means that anybody with decent IT skills should not have a problem. Though I think you need the job offer first. Hiring people from outside the Netherlands and getting them a visa is very normal so it shouldn't be a barrier for anybody who wants to move to Amsterdam. There is also a tax incentive where foreigners don't pay as much tax (30% ruling, the first 30% of your income doesn't get taxed) for the first ten years. Again, if you are sufficiently skilled you should qualify.
