How to align items inside the md-grid-tile differently other than its default center alignment?

You can use ::ng-deep to override the default css of md-grid-tile.

css:

::ng-deep md-grid-tile.mat-grid-tile .mat-figure {
    align-items: initial;  /*vertical alignment*/
    justify-content: initial;  /*horizontal alignment*/
}
