US Citizen making US money while living in another country?

I see many questions about a US citizen making foreign money while abroad, but its difficult to find the answer about a citizen still making US money. Overall, i'd like to know how the tax situation would work if I were to move to Brazil with my wife, but continue to work remotely for my current US located and based company. Brazil has no tax treaty with the US, so I wouldn't be protected as far as I know from double taxation. For this example, let's say I'd be making under 100k. I understand I'd still have to file in both countries, but the Foreign Earned Income Credit applies to earning foreign money, not US money.
