That's strange as both links work fine for me. Well you also find them here:
www.susana.org/lang-en/news/jobs

I have changed the title now to "advisor" (not "expert").
From what I gather in the description, at least the first job does need quite a bit of expertise in water and sanitation.

It is difficult to translate the German term "Entwicklungshelfer" by the way (development worker?).
Anyhow perhaps someone (needs to be German and French speaking) will find these job ads with GIZ in Burundi interesting, that's why we posted them. If you do, please contact the person listed with the job ad for more information if needed.

Regards,
Elisabeth

First link is not working. (Edit: Works now... not sure why I got a 404 before).

A bit off-topic: I find it mildly irritating that the topic header and job description header looks for an advisor for WatSan (you even mention "WatSan experts"), yet the job requirements are for an economist or sociologist and the descriptions sounds like you don't need a WatSan expert at all (e.g. someone who has actual experience with WatSan, i.e. usually not an economist or sociologist).

GIZ Burundi has two open job offers for water/sanitation advisors (sorry, the job ads are only in German):
