Hitch started work at Marvel UK where he started off working on Transformers before working with Furman again on Death's Head. He did some work at Marvel Comics and DC Comics during the late 1980s and early 1990s, in particular his run on She-Hulk, but also carried on at Marvel UK. After that company closed, he provided the art for an issue of Teen Titans and a couple of series at Valiant Comics before returning to Marvel where he would work with inker Paul Neary. It was in the late nineties that he got a series of high-profile assignments, which would mainly include Neary on inks. At Wildstorm, working with Warren Ellis in rebooting Stormwatch and launching The Authority. This led to a year on JLA with Mark Waid and then another return to Marvel. There the art team of Hitch and Neary would join Mark Millar on The Ultimates, The Ultimates 2 and Fantastic Four.
Hitch's career has also been marked by lateness of books, perhaps due to his high detailing. Examples include his run JLA, which was broken up by fill-in artists, a situation which he blamed on bad scheduling on DC Comics' part. There were also long delays in between issues of The Ultimates, which was due to the birth of his child, two house moves, and an office move. His final issue of Fantastic Four with Mark Millar was also done by fill-in artist Stuart Immonen. Hitch stresses that Marvel was more supportive of him during his tardiness than DC.
Hitch has also provided artwork that served as the cover of Empire, a British movie magazine doing a featured article on comic book movies.
