Yes there are jobs and yes the non-profit industry needs your talents. Software jobs in the industry fall into one of 4 buckets in my experience. Don't expect much career growth or pay. Most of the work is in support of fundraising. Be willing to work at a vendor that serves the non-profit industry.
- Web development. Nonprofits need websites. Sometimes they may have a dev on staff, usually they at least have a digital director that can work with devs at web dev vendors. These vendors are usually solely focused on the non-profit market.
- CRM. Non-profits fundraise and they need people to manage the donor database. Usually this is bought from a vendor that specializes in non-profit CRM and those vendors also have devs/DBAs.
- IT. Non-profits need IT to manage networks, phones and equipment. Often they work with IT vendors.
- Devs for conservation work. This is more rare. Still, some non-profits have staff scientists, GIS people, and devs to build out conservation tools, such as data collecting apps, data visualizations or other things. This is rare because most non-profits are trying to convince the government to do the science because the government has much more money and power to recruit. It's rare and maybe a bit of a vanity project to do any science out of the non-profit, though there are a couple of groups that do that.
