Ask HN: Doing moral work as software engineer?

Recently I've been thinking about my job (fintech) and realised I'm having (at best) a neutral to negative impact on society.

Does anyone have experience working in an organisation or on their own that is fulfilling their moral compass/needs? Is it even possible to do this in a for-profit corporation? Maybe working for an NGO could help with this moral vacuum? Doing some volunteering outside of software could be an option but a lot of those require a significant commitment which is hard to manage with a full-time job.

Would be great to hear your experience if you faced this problem and how you dealt with it? And if you managed to do it within the software industry?
