As far as the UK is concerned, it is possible to get skilled work visas for tech jobs in the UK. The company needs to be willing to sponsor you, and some other criteria need to be met. You can get permanent residency after 5 years. Other routes are available depending on your background (if your grandparents were British for instance this is very easy), or if you’re young and interested in studying, degrees now lead to graduate visas. You will likely be taking a pay cut, but you might have a higher standard of living depending on how much you currently make. You will also almost certainly get better holidays (5-6 weeks is fairly normal). See https://www.gov.uk/skilled-worker-visa https://www.gov.uk/skilled-worker-visa for more details
