The word 'Betreiber' (operator) is derived from the verb 'betreiben' (to operate / run). The ending '-er' turns the verb into a male person or institution that performs the action — that is, the person who operates something.

'Betreiber' (operator) is often combined with the thing being operated. Typical examples are the operator of a website, a restaurant, a business, or a network.

In a legal or business context, the operator is often the person responsible for something. Therefore, the word is frequently used with verbs such as 'haften' (to be liable), 'sicherstellen' (to ensure), or 'verantwortlich sein' (to be responsible).

leader / conductor
'der Leiter' and 'der Betreiber' can both refer to someone who carries responsibility. 'der Leiter' fits especially when a person leads a group, a department, or an organization. So it is strongly about leading people. 'der Betreiber' fits more when someone runs a business, a facility, a website, or a service and is responsible for it. This can also be a company, not just an individual person. The words can be confused because both express responsibility. Ask yourself: Is it about a team or a department? Then 'Leiter' is more likely. Is it about running a facility or service? Then 'Betreiber' is more likely.
