35-60k... euros? That's kinda low even in pound sterling. Is this what folks get paid in The Netherlands as a "software engineer"?
We're bound by the collective bargaining agreement (cao) for universities. So it's a bit low even for dutch standards.
However, it's hard to compare it against SV or london positions because the cost of living is lower, and a lot of the conttact is very much in favour of the employee (a company cannot just fire you for example, you get health benefits that are probably very good by us standards).
I'm purposefully not making a case here. The vsnu cao is online[1] and you should make your own deliberation.
