I solved it with this jQuery.
jQuery(document).ready(function(e) {
jQuery('.wp-tiles-byline-wrapper').each(function(e){
var h = jQuery(this).height();
var h2 = jQuery(this).parentsUntil(jQuery('.wp-tiles-tile')).parent().height();
console.log(h2);
jQuery(this).css('margin-top', (h2-h)/2+'px')
})
});
