I spot-checked some of the companies you listed. Problem is that they're a mix of not remote, have complex applications requiring logins which I assume are big time sinks into black holes, the software jobs aren't in the U.S., they use enterprise technology which is fine but just not my skillset, all that sort of thing. Also I'm assuming, maybe wrongly, that big enterprises have a hiring cycle of several months which is just too long for me at the moment.
If you know of any big companies that have startup-like departments than I can apply to separately, that would be great. Otherwise these aren't really a good fit for me, personally. Maybe other people though!
Also, other people have suggested contracting jobs but I'm not really sure what that means, see my comment at https://news.ycombinator.com/item?id=33598270. If you know of a place that is actually always hiring, meaning they will almost certainly hire you if you have skills and are who you say you are, I'd really appreciate some examples, because I don't know what that looks like.
