How to find remote jobs?

I am in bangalore working as staff engineer. I dont like bangalore for a couple of reasons. High cost of living, high cost of raising a child, away aging parents, sheer amount of assault on the senses due to traffic, construction, bad roads and narrow roads. I am planning to move to north either by having a job there or remote. I dont think there are much opportunities in ncr, so maybe remote is the way to go. Can anyone help me on how to find remote jobs that are in US or Europe and work from India? Are there any portals/job sites to look for?
