For that: you might want to think about applying to tech startups directly even if they don't advertise remote jobs (as long as you actually are an extremely good match though and a good way to tell is if the job advertisement is simply a restatement of your resume.) The reason is: a lot of startups are open to this kind of arrangement to the right applicant (and I really do mean the right applicant here.) For example, if the job advertisement is for say - a PHP developer and it doesn't specifically state remote work, then its unlikely they will be open to that kind of arrangement simply because there isn't exactly a shortage of high quality local applicants (PHP is very common.)
On the other hand: if you're applying for a highly specialized job and you can make a persuasive argument as to why you would be an ideal match for the company - the company may be open to your offer. In the end: the only way to know for certain is to ask which you should definitely go for if you specialize.
I'm not saying it can't be done, but taking OPs advise will be much harder than working for a company that has established remotees.
http://workingnomads.co is a curated remote jobs board with fewer listings than remoteOK. There are 9 from the past 24 hours.
Both of those only let you search by title, rather than the details from the descriptions.
Do you have a specific type of company in mind?
