The “(all genders)” bit is probably just based on the fact that they translated the German job ad (in German you have to be more explicit with the male/female/all versions of titles, because the default is usually just the male form). So, it’s not a qualification, but just a way to be inclusive to applicants of all genders (we have a diversity problem in our industry).
The salary is bound to the limits of the public salary bands (collective agreement), that’s where the maximum comes from. (And, you can live quite well in Berlin with ~100k € per year.)
Yep, the German version’s heading is a bit of a mouthful:
Technische*r Direktor*in (m/w/d/x)
Wir suchen eine*n technische*n Direktor*in, der*die die Technologie- und Forschungsstrategie der Sovereign Tech Agency federführend gestaltet und vorantreibt.
