Not knowing anything else about you, it seems like the NSA or other intelligence agency would be something to consider. Or a private intelligence/security company.
I have no idea how to go about it or where, but some kind of skills and interest assessment might be helpful, if you haven't figured out what you're interested in.
I've mostly drifted, with some success, since I got out of the Navy in 1981. My first job was a technical-ish desk job at a shipbuilder, generally related to my enlisted job in the Navy. While there I discovered I liked programming, got a BSCS, and then "drifted" from good CS job to good CS job ever since. I've just done what the man had on his todo list.
