You get an internationally competitive salary, and because they've got a local office, they also comply with the EU's sane employment laws.
I don't really have tips - I joined Atlassian in Sydney and transferred to Atlassian France. After a while I managed to find another job using my personal network.
At least in France some local companies are starting to realise they need to up their salary to compete with international/remote companies, so it should get better.
