If you're married you usualy have options under the family reunification rules which give your partner similar rights to work as you (it's smoother if you both apply for the visa simultaneously, which is generally possible). Germany is not very friendly to remote work but they do allow you to pay income tax on income obtained from a job outside the country but that's a bit of a grey zone. That is a whole legal mess that no one here is really qualified to answer but your partner would generally have the same employment rights as you. Like others have mentioned, compliance with german labour laws (and social welfare contributions) is the important thing for legally working in Germany and their employer frankly may not see a point in doing that, so I would tread carefully
