The role of a UX designer is to create a positive user experience by designing and improving the usability, accessibility, and pleasure of a product, website, or application.
UX designers conduct user research, create personas, design user flows, prototype, collaborate with developers, conduct usability testing, and continuously improve the product's design and user experience.
Their goal is to create an interface that meets the needs of users, making it easy for them to interact with the product and ultimately achieve their goals.
