The order of authors varies by field. I believe in biology it usually starts with the person who did most of the work (or people, but if more than one it's explicitly noted), everyone who contributed in the middle, principal investigator (i.e. head of lab) last.
In this case I notice that they first sorted all the instadeep people to the front, and biontech people to the end... not sure what I'm supposed to take away from the ordering, but it's not random.
