Have you thought of doing some research? There are lots of startups, but which ones would you be interested in working for? Which ones could benefit from your skills and experience?
Perhaps connecting with people in your field, e.g. through forums for the products / frameworks / languages / whatever you use might open some doors.
You might also want to edit your post, put some information in there that would attract the attention of would-be employers. As it currently stands, I think quite a few people would be put off by it.
