Experienced CSS Developer Needed for Responsive UI & Styling

We are seeking a highly skilled CSS Developer to create clean, modern, responsive, and beautifully styled user interfaces for our web application. The ideal candidate must have strong expertise in CSS3, responsive design, flexbox, CSS grid, animations, transitions, custom components, and cross-browser compatibility.

Your primary responsibility will be converting Figma/Adobe XD mockups into pixel-perfect CSS styles and ensuring every component looks polished across all screen sizes. This includes working with layout systems, variables, custom properties, responsive breakpoints, and utility-based styling. You will collaborate with frontend and backend developers to ensure seamless integration and consistent design implementation.

You will be responsible for creating reusable styling patterns, solving layout issues, optimizing CSS performance, and ensuring accessibility. Strong attention to detail is crucial because the design must match the mockups with high accuracy. Experience writing scalable CSS architecture (BEM, OOCSS, SMACSS) is a big plus.

Your role will also include implementing animations, hover effects, transitions, component themes, and custom styling for forms, tables, dashboards, and landing pages. A strong understanding of pseudo-elements, pseudo-classes, specificity, and browser rendering behavior is essential.

If you are someone who enjoys styling complex UIs, fixing layout challenges, and crafting beautiful interfaces that feel smooth and consistent, this project is an excellent fit.
