Nice! Happy to help. And let me know if you're ever in Berlin.

Kyle, I'm inspired by your question! I finally made an account just so I could comment :) I'm a product designer and user researcher in Berlin.

I've been / am in the same position as you: have worked with good people at decent startups, agencies and larger companies but didn't find the work intrinsically motivating. I want to help people and think design can be a powerful force for change.

To that end I've done quite a bit of research on the topic of "design for good" or whatever you might want to call it. Here's what I've come up with so far:

• Work for an agency that focuses on these kinds of projects, like Radish Lab.
• Work for any company that has a mission you believe in. For example, if you're into health, one of Berlin's solid startups, Clue, has an opening right now. Another Berlin startup in this area is Ada. A more known example would be Headspace.
• Work at a hospital. There are some, especially in developed countries, hiring designers to work with them. For example, the Toronto General Hospital has an in-house 'agency' of sorts: Healthcare Human Factors.
• Consider working on a product that may not be directly "for good" itself, but would ease the pain of many people with better design. Some examples: financial tools (banking, taxes), transportation (ride sharing, public transit), or anything that many people use frequently.

Some others mentioned these already:

• Work for a B Corp.
• Work for the government (some others mentioned NHS in the UK).
• Work for a non-profit, like Acumen.
• Work for the non-profit branch of a for-profit, like IDEO.org and OpenIDEO.

I've also subscribed to a couple newsletters I find helpful:

• Pivot to Civic sends out new job ads for those in tech interested in social impact.
• Public Design Jobs has a newsletter with openings for 'design and innovation jobs in the public sector.'
• Offscreen Dispatch focuses on the human side of technology.
• The Social Enterprise Jobs Google group has some gems as well, like this opening at Kiva.

If you're particularly interested in the healthcare topic, then you can check out a post I wrote about this recently. I dive further into it, including Masters programs in Europe and books to read.

Hope it helps!
