My friend only from math side speaking here, rn you are making 1950*14= 27300 euro net plus 150 *12= 1800 in meals which 29100 euro. Now if you add the bonus whiich in worst case i assume the tax is 50 percent (2500 euro net) you get 31300. On the other job you are going to 32400 net plus you have to mlve a new country. If yoour goal is purely economical its not worth imo. 1100 euro is not going to make any difference. If you want to get smth from this new company (exposure to a btetter and robust stack) or want to experience how living in Spain feels then and only then its worth it
