I think it's going to be tough to work remotely in that capacity. Most funds do allow that -- but only if you have worked for them for a period of time and have really proven yourself.

If Poland does not have many funds you ought to consider moving to somewhere that does (maybe you could apply to one of the graduate degree quant finance/financial engineering programs?)

Or, if this is the work that you love and are good at - consider trying to raise capital. There's not much to know. Most people tap friends and family for the initial capital and give it a go. There are plenty of great traders that started with little more than a small sum of capital and a tiny room to work out of.
