If I were you, I'd connect directly with people working in security, either security for a "normal" company or working for a security company.

I can believe if you say that job posting is slightly biased towards senior positions, but I'm sure you'll find good opportunities easily, it's a very specialized job and it's hard to find good people.

If you let managers (or hr) know that you exist, a position will appear.
