Ask HN: Nonprofits hiring web devs / software engineers?

Hello HN. Lately I've been looking at working remotely for a nonprofit organization. I'm a web developer with experience on the full stack, and it's something I'm willing to take a pay cut for. I'm realizing it's actually quite difficult to find lists of nonprofit organizations hiring developers. Any of the usual outlets (angel.co, indeed, etc.) seem to make it almost impossible to filter on nonprofits alone. Does anyone have any advice on some good places to find such nonprofits? Thank you!
