 Sales engineers, like their sales representative counterparts, are hired based on their geographic location rather than their proximity to the corporate, or even regional, office.Working in another part of the country, or even outside the country, where the corporate offices are, a sales engineer may only make it to corporate headquarters once or twice each year.A key differentiator between sales engineers and other roles within the organization is that a sales engineer is usually compensated by salary plus commission, as most sales representatives are.
