We are looking for an experienced UI UX Designer with strong React frontend development skills to design and develop a complete production ready React theme for our upcoming SaaS product. We already have an existing HTML CSS mockup theme that will be provided as a reference. However, we are not looking for a simple conversion of the existing design into React. We want someone who can understand the existing product concept, identify UX and UI limitations, and create a significantly better, modern, intuitive and polished user experience. What You Will Work On Analyze our existing HTML CSS mockup and understand the product workflow. Redesign and improve the UI UX wherever required. Convert the approved design into a fully functional React theme. Create a clean and scalable reusable component structure.

Maintain consistent typography, spacing, colors, icons, buttons, forms and interaction patterns throughout the application. Responsive Design The theme must be truly responsive across all modern devices and screen sizes. Desktop Laptop Large monitors Small laptops Tablets iPad and similar devices Mobile phones Portrait and landscape orientations Different screen widths and resolutions The interface should intelligently adapt navigation, tables, forms, cards, dialogs and other components according to the available screen size. The design must be tested across multiple screen resolutions and not only standard desktop and mobile breakpoints. What We Are Looking For Someone who understands product UX and not just visual design. The final product should be modern, clean, professional, intuitive, fast, lightweight, consistent, accessible and easy to use. We will provide an existing HTML CSS mockup for reference. Your responsibility is to understand the existing design, identify areas for improvement, redesign where necessary and implement the final experience in React.
