(A) としてまじき (B) is a formal written set phrase meaning that (B) is evaluated as unsuitable, unworthy, or inappropriate for someone in the position/occupation of (A). It is directly attached to a noun since it originates from the attributive (noun modifying) form of the classical Japanese auxiliary まい - “should not” or “will not” (nowadays まじ, however, has lost it's prohibitive nuance). Words like 言動、行為、行動、発言、姿 are very common as (B).
