Maybe he would work at Hogwarts. There are always things to do around the school during summer, like helping with the maintenance of the castle or taking care of the magical creatures in the Forbidden Forest under the guidance of Hagrid. This would give him a chance to be closer to the place he loves and also learn more about Hogwarts.
He could work at Weasleys' Wizard Wheezes. He has a good relationship with the Weasley family, and it would be a fun place for him to work, helping with inventing and selling all kinds of magical pranks and toys.
Another possibility is that he works at the Ministry of Magic. Given his status as the Boy Who Lived, he might be given some special tasks or a regular job in a department. For example, he could be in the Auror department, learning from the Aurors and doing some basic tasks like filing reports or helping with the research on dark wizards.
