Summary We are seeking a senior-level PyQt developer to modernize the UI of an existing desktop application built with Qt Widgets (not Qt Quick/QML). This is a production desktop application with multiple screens and data-heavy views (tables, forms, dialogs). The goal is to significantly improve visual structure, usability, and consistency while staying within Qt widget constraints. This is not a web redesign. All improvements must be implemented directly in PyQt using Qt Widgets and QSS. Responsibilities -Audit and modernize the current UI structure -Establish a consistent design system (spacing, typography, color hierarchy) -Refactor layouts for improved visual clarity -Improve QTableView / form readability -Implement styling using Qt Stylesheets (QSS) -Ensure maintainable and reusable UI components Required Experience: -Strong experience with PyQt / Qt Widgets -Hands-on experience styling applications with QSS -Experience modernizing existing desktop software -Strong understanding of layout systems and reusable UI patterns -Ability to balance design improvements with Qt implementation constraints To Apply Please provide: 1. Examples of Qt / PyQt desktop applications you personally implemented 2. Screenshots of the UI 3. A brief explanation of what you improved visually and structurally 4. Your experience working with QSS We will not accept proposal without exact example you built directly.
