Can I ask what your job title is? This sounds like an area i'd be interested in but having only experience with tech i'm not sure of any tips or tricks to finding these hybrid jobs.
My route in was pretty idiosyncratic, and I think that's true of many people in these kinds of jobs. A more standard way to transition into this kind of research/consulting/policy work from tech might be go for jobs in technology or innovation policy. If you're in the UK I can point out some orgs that do that kind of work but in any country there will be various think tanks, policy consultancies, etc.
I'd be interested in hearing about tech and innovation policy orgs in the UK. Currently I think I either want to work in the civil service or in such an org. As you say, it would be nice to have a positive impact on the world.
