What is the position of "computer room staff on duty" in the business department of securities company?

In the past, the entity business department required the business department to have a backup staff besides the computer administrator, which was an essential bench staff. Newcomers can take this opportunity to enter the company first, which is relatively safe and without too much performance pressure. But now the new account is opened at the counter and the sales department is opened at the store, which may be cancelled, so it is necessary to consider jumping ship.
