• SynonymチーフNeutralA loanword for a chief or person in charge, as in 「チーフデザイナー」; unlike 「部長」, it is not a formal title for head of a department.
• Antonym平社員ひらしゃいんNeutralThe opposite of 「部長」: an ordinary employee with no title or position.

Use 「部長」 for the formal title of a department head; 「チーフ」 covers a general chief or person in charge, and 「平社員」 is the opposite — a rank-and-file employee with no title.
