Yes, in the tech-industry there's a very high demand. It's much easier to do this as junior than senior (hard with a family). The benefits are: work experience, international experience, expanding your social network, nearly free university education (germany only). There's also cheap health care and 4-6 weeks holiday. There are many downsides too, as the other commenter said (salary, culture shock and many more). The main benefit is work experience and possible debt-free university degree. If I were American I'd first try other states/Canada first though.
