- 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 cooperation with Product Managers and Frontend Engineers
Requirements
- Several years of experience in designing B2B or enterprise software
- Very good knowledge of 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 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.
