There are all kinds of OSS projects out there. Some companies build OSS as part of their product strategy (I run one of those companies: http://ionicframework.com/ http://ionicframework.com/). Technically, we have several people on the team getting paid full time to work on OSS. But in the past I've done contract work on OSS when a company had the desire to build a reputation in a specific field, or was using a project that needed extra help. All of those projects have a different type of work style. I'd say the former (OSS as a product) is more like working on product at a startup, so is more intense. Finding the former is easier as well, just look at all the OSS startups today: Docker, RethinkDB, etc.
