Do you have a list of places where scientists are inviting coders to come and talk to them about coding practices? (Or organizations that can help with this)
What are some non-profits who work on enabling people in poorer countries to withstand disturbances? Are they looking for coders?
Who is working on carbon capture and looking for volunteer collaborators?
The International Research Institute on Climate and Society at Columbia University's Earth Institute is looking for a programmer to work on their Data Library. Unfortunately I don't see a way to get a permalink to the job listing; you can find it by going to https://jobs.columbia.edu/ , clicking "SEARCH OPEN POSITIONS" in the left nav, and specifying Department 6061.
I'm not affiliated with the group. I actually interviewed for the position last week, but probably won't end up taking it.
I can tell you that every DOE lab has scientists and programmers working together. In fact, the two largest super computers, Summit and Sierra, are GPU based, and there's a huge decrease in power consumption. For example: Summit (#1) has ~7.5x the power of Titan (#9, and at the same facility: ORNL) but only uses ~20% more electricity (Summit and Sierra are GPU based)[0]. Aurora, the planned exascale machine, will be 5x Summit and only use 20MW (~2x power) (actually that's the number that's the hard upper limit). That's a big deal. And a bunch of teams there are working on making everything more efficient and how to better utilize resources.
