Ancient Mesopotamia society members held jobs such as slaves, priests, farmers, weavers, tradesmen, pottery, and herdsman. Your character could interact with a member of society with any one of these occupations (even with the King of Mesopotamian society) depending on their societal status. Keep in mind that priests were of the upper class and slaves were of the lower class. Also note that there was no rigid structure to societal class so at anytime a person's societal status could potentially change.
Keep in mind that two major cultural groups existed during this time period in this area. This includes the Sumerians (responsible for temples and palaces, city states, and first writings) and the Akkadians (established the first Mesopotamian empire). These two groups existed together peacefully for the most part. Your character could belong to one of these cultural groups.
Such as the construction of roads and aqueducts, and of sewers that could wash the filth of the city into the Tiber.
