No, you don’t necessarily. Estonia has an e-Residency program targeted exactly at this scenario: Having a company in Estonia but living abroad. However, Germany being Germany, you will still have to deal with the Finanzamt and all the nice stuff that comes with it.

In Germany the pension insurance (DRV) will come around after a few years and demand a six digit figure from both your company and the employee, plus interest. You can also end up with criminal charges filed against you.
