For our client, we are looking for a freelance Product Designer & Prototyper (m/f/d) for a three-month project in the field of AI-based UX / Product Design & Prototyping, with a minimum of 30 hours/week utilization and preferably a prompt start. The assignment can be carried out remotely. Very good English skills are necessary due to the international environment.

Responsibilities

You will accompany the entire process from UX concept through functional prototypes using AI coding tools to the release of features in production.

Our Requirements

• Building functional 0/1 prototypes with modern AI coding tools (Cursor, Claude Code, v0) instead of pure Figma mockups
• Designing complex, multi-stage B2B processes and intuitive interaction patterns for data-heavy tools (tables, filters, search, comparisons, review flows)
• Conceptualizing interaction models for AI agents, including confidence signals, human-in-the-loop checks, and explainable results
• Iterating and further developing existing product features to accelerate workflows for daily professional use
• Conducting rapid user tests and customer interviews, and iteratively incorporating feedback within a few days
• Accompanying features to a production-ready release in close collaboration with Product Managers and Frontend Engineers

Requirements

• Several years of experience in designing B2B or enterprise software
• Very good knowledge in creating functional UIs with AI coding tools (e.g., Cursor, Claude Code, Lovable, Replit or similar)
• Basic frontend/UI development knowledge
• Fluent English skills (project language primarily English) and good German skills

Nice to have

• Experience in designing AI or agent-based products: confidence signals, human-in-the-loop checks, explainable results (Explainable AI).
• Exposure to software in the areas of industry, manufacturing, supply chain, purchasing/procurement, or ERP (e.g., SAP).
• Experience in building or further developing design systems.
