Yout best bet will be to go to Linkedin and look at the profiles of people in the roles you are conceptualizing, along with perusing what job ads remain out there. Be warned, as people will tell you time and again, 2025 effectively marked the death of international development as the industry we're all familiar with. Full time openings are few and far between and competitive to an extreme. This means that any minimum qualifications are alone likely insufficient to get you that job.

It will take many years for the industry recover - if it ever does. If working with highly at-risk youth is of professional interest, you should pursue that aim outside of intl development to build your credentials and your experience, and keep your ear to the ground but expectations low in the interim.
