Who is a person with expert knowledge of the responsibilities and competencies of a specific position?

A person with expert knowledge of the responsibilities and competencies of a specific position is known as a Subject Matter Expert (SME). This individual possesses in-depth understanding and specialized knowledge regarding the tasks, skills, and requirements associated with a particular role. SMEs are often relied upon during hiring processes, development of training programs, or when crafting job descriptions to ensure a comprehensive and accurate representation of what the position entails.

While supervisors may have a good understanding of their team's roles, their expertise is typically more broad and oriented toward management and operational aspects. Interview panels may include SMEs, but they are more focused on evaluating candidates rather than possessing expert knowledge of the position itself. Therefore, the most appropriate choice is the Subject Matter Expert, as their role is directly tied to in-depth knowledge of specific job responsibilities and competencies.
