Where to look for junior vacancies for food?

Question

Java

I want to advance in real projects with real challenges. Where can I find vacancies for java junior. Maybe not vacancies, I don’t know how to describe it better. In general, I want to write code in a team, remotely, for free. I want to be in some kind of open source project. Whether it's web or Android. Where to look for these?
PS I participated a little in writing jtalks as a junior. I like it. Now the time has come - I want more.
