Been doing a research about positions web designers hold in agencies or independently. I figured out these
A Web designer can hold a large range of titles and job positions due to their experience in almost all fields of design.
Front End Developer
Full Stack Developer
Its important to know that when a Agency is hiring it will not hire a person just because their last position had the same title as the current one they are employing for. They will rather look at the skills and the knowledge that the Web Designer knows and is proficient at.
