Whether he is a senior or middle level manager can only be determined by combining the company's organizational structure and appointment documents.

Generally speaking, supervisors, managers and directors are all middle management levels in the company's internal appointment documents.

In external communications, the title will be magnified, and the outside world will think that the operations manager is a senior management level of the company.

In the company's business management, the operations manager may also be the first person in charge of this operations section, and in essence, the top leader of this section.

So whether he is a middle level manager or a senior level manager depends on the specific situation of the company.
