A professional role in insurance. A person who identifies, examines and classifies the degree of risk that a proposed insurance policy represents to determine whether or not to provide coverage, and if so, at what rate.
It is common for the underwriter to have tasks within multiple areas at the insurance company. It can, for example, work on preparing insurance solutions for customers and then assess what risk they pose and then determine the premium, ie what could pay for the insurance.
But in addition to this, they can also help out building completely new insurance products.
