Can I work remotely in Germany on a Schengen short-stay visa?

Accepted answer
Generally speaking, no. Working remotely from Germany means working in Germany, and if that isn't covered by the activities permitted by a business visa, you need a work permit to do so.
You did not state your nationality. I'm assuming that you're not an EU/EEA citizen, or you wouldn't have a visa.
Depending on your employer, you might qualify for a work permit as an intra-company transfer. For that, ask on Expatriates Stack Exchange.
Your visa may explicitly permit you to work. That isn't normal.
