There are a lot of professions that involve frequent traveling. If you are looking for a generic term, then road warrior fits the bill.
Merriam-Webster defines road warrior as:
a person who travels a lot especially as part of his or her job
a person who travels frequently especially on business
You can use the word that describes the area to be covered. Ex: "District manager", "National salesperson", "International buyer".
