Given that this is a completely different context, one where someone is still outside the org and trying to get your attention to become their advocate it is a totally different vibe from TFA.

I don't see how 'humble, hungry and smart' will go together in most applicants, you'll be lucky to have one out of three, extremely happy to get two and all three is usually a question of broken self assessment.

Adding 'hungry' also seems to select for people in need, giving you an advantage over them in negotiations. As for humility: you will not find it in most sub 40 year olds, they don't know what they don't know yet. So this might cause good candidates to back out.

Finally, the extra heading 'We cannot hire within these countries' is superfluous, it is already covered by the previous heading.

hth.
