In Germany at the senior (10+ years) scale €70k/year is not unusual & if you work for the better paid companies (like google) you can expect significantly more.
A software engineer should get _at least_ EG10 which ends up being >50k e.g. in Berlin.
Also my experience reflects living in Berlin (& previously Vienna), in Munich or Frankfurt salaries may be higher.
All this doesn't hold true for a lot of immigrant labor and people working at startups, where you are offered 30-40k€ with a masters (these kindd employ most of the immigrant labor I think - of course there's the odd 100k YC). Imho this (at current rent levels) is exploitation and something which makes working in Munich not particularly attractive for anyone not from Germany or getting a job at a car company.
2. Big caveat: There are absolutely many conservative managers who insist on speaking perfect German / not switching the team language because of the new junior dev, so there will definitely be job openings where immigrants are discriminated against at those big corporates, but IME that doesn't apply to the companies as a whole.
The reverse is obviously also true: If you want to work in a young, international, open culture, you might prefer startups, but most of them offer lower salaries.
