There's not much of an ecosystem, but rather good companies in both places: - madrid: cartodb, ontruck, jobandtalent, cabify,... - bcn: typeform, wallapop,... Some of those previous companies have English as the working language, so that shouldn't be a problem. But in some companies, even the senior leadership might struggle with English. You will need to test that during the recruiting process :) Freelancing might be more challenging, because of the smaller pool of opportunities. Salaries are 20-30% lower than in London, but as a foreigner relocating to Spain, you have a tax break that makes the net salary closer.
