TLDR: Where to find organizations/companies that recruit hackers (as volunteers or payed employees), to develop products (hardware/software) to help others around the world or the local community where it is based?

I became a nomad last Christmas, in order to be able to explore more. Such that there is a better balance between my time where I discover new, while working and studying. This turned out to be great, and after 6 months I'm very happy how it all turned out and has evolved so far.

So enough about that. My educational background is a cross between electrical engineering, artistic education, game development and general computer science. Most of it is learned on my own, and I continue to learn alone or within an (online) community.

I always wanted to help other people, but never really have done so, beyond some local stuff. In the last months I did start doing volunteering, but I never could use my hacker skills (Hardware + (mostly) Software) while doing so.

This website/community often gives me great ideas because of articles shared or questions asked by other people. Therefore I would like to ask a question of my own:

Are there any specific websites/communities where I can find more information about organizations and companies that recruit "hackers" to help them, help others. Could be both on a volunteering, freelance or permanent basis. I'm also location independent, so it could be pretty much anywhere on this planet.
