I was in the same place when I was 26 (am an engineer, work on undersea robotics/hydraulics). Never really got out, worked my butt off, and the nature of my work is that I disappear off on oil rigs and the like for weeks and months at a time and never really associate with anyone other than my supervisor if that. Spending all day working on robot arms on a boat in the Baltic doesn't do much for your social life.
My advice is to go for girls who are a bit younger than you, say 20-22. That is how I met my wife, and 5 years is hardly a big age gap.
I didn't have any luck with the girls I met who were "my age," they all seemed tired and angry, burdened down by past relationships, that sort of thing.
Just be careful that you don't get taken advantage of as a lot of women in their mid-to-late twenties are looking for a man, any man, who they can "settle down with." Don't be the guy who is just a paycheck, find someone who has similar interests, someone who wants the same things as you do and be a man, be a lover. And above all else, have a good time! Meeting people, dating, it's supposed to be fun - if it seems like work, if it seems like a headache then re-think what you are doing.
