Compensation at StorPool is location-adjusted. We align our ranges with each local market rather than having a single global scale. So the numbers look different in Bulgaria vs. Switzerland (or elsewhere), but the goal is to be competitive for top engineers in each region, which means 6+ figures for senior engineers in the US, Switzerland, Denmark, Luxembourg, Germany, etc.

I'd suggest aiming for fairness in terms of Quality of Life rather than local markets, otherwise you'll keep Bulgarians poor while make Americans even richer. The main benefit of remote work is to escape local underpaid markets. I'm pretty sure you are missing on some great Bulgarian talent because they work for US, Swiss companies remotely who pay according to their market.
