岗位 (gǎng wèi) literally combines 岗 (gǎng), meaning 'post' or 'station', and 位 (wèi), meaning 'position' or 'place'. Together, it refers to a specific job role within an organization — not just any job, but a defined, official position with assigned duties, responsibilities, and often a formal title. It emphasizes structure and function within a workplace hierarchy.

This term is commonly used in formal, professional, or administrative contexts: job postings, HR documents, performance reviews, or organizational charts. It’s more precise and institutional than the general word 工作 (gōng zuò, 'work/job') and carries connotations of duty, accountability, and official assignment — for example, a security guard’s 岗位 is their designated patrol area and responsibilities, not just their employment status.
