As a remote UX designer, your responsibilities are to help your client or employer design and improve the user experience of a website, application, or piece of software, such as an operating system. Your specific duties include design functions, such as developing wireframes, which are simplified designs of websites or visual components of an app that help conceptualize and communicate the functions of the program. You also conduct testing of finished products and use feedback from users or beta testers to improve the user experience.
