Desktop UI Developer (AI Software)

Quadcode.ai is an autonomous native AI studio and multi-agent workspace for software development and design.

We are building a desktop AI IDE that combines specialized AI agents with a rich visual development environment. The product brings together code, visual editors, Live Interfaces, repository-wide RAG, and built-in multimedia capabilities for UI/UX, 3D, video, and audio.

Quadcode.ai can also orchestrate Claude Code and Codex CLI sessions through MCP, allowing different AI agents and development workflows to work together within a single desktop application.

The interface is a core part of the product. We are building a complex, highly interactive, and visually rich application with multiple views, editors, panels, dynamic states, real-time updates, animations, graphics, and dynamically generated interfaces.

Some parts of the UI are generated dynamically and currently involve JavaScript, while the core application is built with Python, PySide6, C++.

We are looking for a Desktop UI Developer who enjoys building sophisticated applications and is comfortable working across different technologies to create complex, polished, and highly interactive interfaces.

Tasks

• Develop and evolve the UI of the AI IDE.
• Build complex, interactive UI components, screens, and workflows.
• Turn product and design concepts into polished, production-ready interfaces.
• Work with dynamically generated interfaces and integrate UI components implemented with different technologies.
• Develop custom UI components, interactions, animations, graphics, and visual elements.
• Work with dynamic data, asynchronous operations, real-time updates, and complex application states.
• Keep complex interfaces responsive, performant, and maintainable.
• Contribute to UI architecture and technical decisions.
• Own UI features end-to-end - from implementation and interaction logic to integration, performance, and final visual polish.
• Collaborate closely with backend engineers, AI engineers, and product/design specialists to integrate the interface with the underlying systems.

Requirements

• 3+ years of professional experience developing complex, interactive UI for desktop or other applications, not just websites or simple web interfaces.
• Strong programming skills in Python and/or C++.
• Experience with JavaScript.
• Strong understanding of UI architecture, component design, application state management, and interaction patterns.
• Experience creating custom UI components, non-standard interactions, animations, graphics, and visual elements.
• Experience with asynchronous programming, multithreading, and performance optimization in applications.
• Understanding of UI responsiveness and performance.
• Strong attention to visual details, usability, and interaction quality.
• Ability to work with rapidly changing requirements and learn new technologies when needed.
• Passion for modern AI technologies and interest in AI-powered development tools.
• English - minimum B1; fluent Russian.
• Portfolio or examples of complex interfaces you have developed.

Nice to have

• Experience with Qt / PySide / PyQt.
• Experience with QML / Qt Quick.
• Experience with advanced animations and interactive visual elements.
• Experience with 2D/3D graphics, rendering, visualization, or multimedia.
• Experience integrating design systems or Figma designs into production applications.
• Experience with developer tools, IDEs, editors, creative tools, or AI/LLM-powered applications.

We offer

• Full-time remote work (service provider contract).
• Competitive compensation (EUR, USD).
• Flexible working hours.
• The opportunity to show creativity, generate ideas, and directly influence the architecture of the AI product.
• Access to cutting-edge AI tools and platforms.
• A team of professionals specializing in AI.
• Positive and friendly atmosphere.

Show us what you have built

When applying, please provide examples of complex interfaces you have developed. This can include links, screenshots, images, or short video demos of interfaces you have built, as well as relevant GitHub/GitLab projects or published applications.
