In the TV series "Stranger Things", what job does Jim Hopper have?

In the TV series "Stranger Things," Jim Hopper works as the chief of police in Hawkins, Indiana.

Hopper, played by David Harbour, is introduced as the head of the small town's police department. He initially appears tired, cynical, and reluctant to get involved in trouble, but Will Byers's disappearance draws him into the investigation surrounding Hawkins National Laboratory and the Upside Down.

His police role gives the story an adult investigative perspective alongside the children's search for Will. Hopper uses official authority, police records, questioning, and knowledge of Hawkins to uncover the laboratory's cover-up. His experience also makes him one of the first adults willing to believe that something supernatural is happening.

Viewers sometimes call Hopper a sheriff because he is the town's senior law-enforcement officer and is occasionally referred to informally as "Sheriff Hopper." The show's character descriptions and story identify his formal position as chief of the Hawkins Police Department. His later relationship with Joyce Byers and his guardianship of Eleven expand his role beyond law enforcement, but do not change the answer to this question.
