UX/UI Designer
- Producing UI layouts and screensNN/g expects anyone to make decent-looking UI; judgement isn't easy to automate
- Prototyping and testing complex interactionsNN/g: prototype from a detailed prompt and test with users earlier
- Designing AI-powered featuresNN/g expects trust to be a major design problem for AI experiences
Software Architect
- Documenting the architecture with diagrams and decision recordsOne study: developers rated LLM-made architecture docs useful; diagrams limited
- Testing design ideas and trade-offsA review: AI is studied most for architecture decisions; few trade-off examples
- Designing systems that include LLM componentsInfoQ: RAG is common but takes effort, and agents need ongoing testing
