Boxshifter did the work allready and calculated some net income from the available gross income figures. The german tax and social security systems are very complicated so the actual figures might vary a bit, but this is pretty close to what my tax accountant got as well.
The pay is not really good especially for the required experience (no, i'm not talking what they posted on the website, rather about what they use as internal requirements) and the intended operation. It is well below Lufthansa's pay and around between 10% to 1% higher than that earned at Air Berlin if you calculate it around pure longrange flying.
But then, as EAM said, if you don't like it just don't apply.
