Depends how technical you are and want to be and what kind of balance you want between IT and Social Sciences.
If you are into programming and deep technical thinking then you can get into the commercial AI world, expert systems, prediction systems / modelling etc - though this will still be very heavily IT focused, just in a social science setting. Developing commercial AI can include both cognitive and behavioural psychology aspects as well as biology, physics and more.
You could step away slightly from the technical programming side and become more of an analyst, which will probably focus more on the social sciences rather than the programming.
In terms of opportunities, you can probably find some jobs that have a small part of the role including the aspects you want, and then move on from there. Once you've moved into a field that has connections in these areas, you can start to network with people that do that kind of work, and see which area is best for you.
Your best bet is looking into the commercial AI type areas or at a research role looking into (for example) user centric design patterns, or other analytical type work.
You could try contacting universities to see if you can work your way into their support staff and help them work on research projects (though getting anywhere here can be nigh on impossible).
But you will always have comprimises to make if you want 'pure social sciences' - as social sciences are about people - which means if you were to work with Psychologists, Therapists, Counsellers, etc, you are likely to only find admin/support roles.
In any case you will need a good grounding in the relevant subjects e.g. Psychology, and it would be good if you had some experience - e.g. volunteer counselling - as this will give you practical knowledge of what the theory is all about.
You also need to narrow your focus from "Social Sciences" to something more specific - e.g. behavioural psychology, child pscyhology, philosophy, psychotherapy, cognitive psychology etc, even economics
Anyway, hope those ramblings give you some food for thought
