Suggestions on where to post nonprofit IT position?

Hi everyone!

We're having a hard time recruiting folks with IT experience in the nonprofit sector for our Cybersecurity and AI Lead position. It's a cool gig (I believe!) - part-time, contract position at $82 / hour. However, I'm not sure we're posting it in the right places - over 90% of the folks who've applied thus far have experience ONLY in the corporate, for-profit sector. We've posted on Idealist, LinkedIn, and a few social media groups (like Nonprofit AF, nonprofit tech groups on LinkedIn, etc)

Nonprofit experience and a demonstrated commitment to fighting poverty, racism, and/or climate change is critical to the role.

Any suggestions about where we might post the position?
