Can you vote in a German election or can you vote as a US citizen when overseas in Germany?
Are you required to file a tax report by the US government when overseas as a US citizen?
German laws (jurisdiction) governs German elections. I have never tried to vote in a German election so I can’t confirm one way or another, if Germany allows non-citizens to vote. I assume not.
As I am paid in the US, by a US company, even when I work overseas, yes I still file US taxes. I would point out that the US tax filing laws are far different than most other nations. With the exception of a handful of nations, there is no tax on income earned outside the jurisdiction of most nations.
