Sorry that you're having trouble finding work. It scares me that you went from having your choice of top gigs to unemployed. I guess the safest way to guard against that is to get promoted out of an IC role, not that it helps you now. There are guys your age at my company who work slower and more carefully, and fewer hours than the young folks, but they are directors so basically unimpeachable. They're not judged by volume or velocity but I guess on wisdom and political skill.
