What is a word for an employee who works at geographically different location than the rest of the team?

I am aware of the word remote, but in these times, remote has come to mean people working from home. I am trying to distinguish that from someone who works at a remote location.

Solution 1:

Not one word, but one generally refers to an employee who works at geographically different location than the rest of the team as a field-office worker, i.e., a person who works in a field office or in the field. From Lexico:

field office: a subsidiary office located in the field, away from a main office or headquarters

in the field: (of an employee) away from the home office; working while traveling

Solution 2:

I think detached employee is the expression you are looking for:

In the case of employment, under the agreement, a detached worker is an employee whose employer sends him or her from one country to work temporarily in the other country for the same employer or for an affiliate of that employer.
