Candidates evaluating offers should compare true net income rather than gross salary alone.

A Algorithmic Trading Systems Engineer earning €52K permanently takes home approximately €36,724 per year after tax in Spain.

Day rates above this produce a higher net income; rates below it mean the permanent role pays more after tax.
