Principal Product Designer, AI Experiences

Microsoft Microsoft · Big Tech · London, United Kingdom +1 · Product Design

Product Designer for Microsoft's Superintelligence Team, focusing on end-to-end UX for AI product surfaces like MM Labs and Playground. This role leverages AI-native tools and agentic coding workflows to rapidly prototype and ship UI, bridging the gap between design and engineering. The designer will collaborate with researchers and model designers, contribute to design systems, and use data to inform decisions, with a high bar for visual craft and interaction quality.

What you'd actually do

  1. Own the UX for flagship AI surfaces: Design and ship the end-to-end user experience for MM Labs, Playground, marketing pages, and model specification tools — from information architecture and interaction flows to pixel-level visual polish.
  2. Design and build: Use AI-native workflows (Cursor, GitHub Copilot, v0, or equivalent agentic coding tools) to move fluidly from design concepts to working prototypes and production-quality frontend code. Own the UI layer end-to-end when needed.
  3. Prototype at speed: Rapidly produce interactive, high-fidelity prototypes to test new interaction paradigms for multimodal, agentic, and copilot-style AI experiences. Use AI tools to compress iteration cycles from days to hours.
  4. Elevate visual craft and interaction quality: Apply strong graphic design foundations — typography, layout, color, motion — to create experiences that feel polished, intentional, and trustworthy. Sweat the details that make AI feel human.
  5. Partner with model designers and researchers: Collaborate closely with model designers (who shape how the AI speaks and behaves) and researchers (who build the underlying capabilities) to ensure the UX faithfully represents model personality and strengths.

Skills

Required

  • Bachelor's Degree in Product Design, Graphic Design, Human-Computer Interaction, Interaction Design, or related field AND 5+ years experience in product or service design OR Master's Degree in a related field AND 3+ years experience OR equivalent experience.
  • A portfolio demonstrating exceptional visual design craft and interaction design — with shipped products, not just concepts
  • Demonstrated use of AI-native design and prototyping workflows: you actively use agentic coding tools (e.g., Cursor, GitHub Copilot, v0, Bolt, or similar) to produce working UI, not just static mockups
  • Ability to write or direct frontend code (HTML/CSS/JavaScript/React or equivalent) using AI coding assistants — you don't need to be a software engineer, but you can ship production-quality UI with AI tools
  • Strong foundations in graphic design: typography, layout, color theory, and visual hierarchy
  • Experience designing for web-based tools, developer-facing products, or AI/ML interfaces
  • Track record of shipping products end-to-end with high craft and attention to detail, in environments where you owned outcomes — not just deliverables

Nice to have

  • Experience designing for AI, LLM, or conversational products — understanding how non-deterministic model behavior affects UX decisions
  • Portfolio demonstrating before/after impact: designs that measurably improved user engagement, comprehension, or task success
  • Experience with motion design, micro-interactions, or advanced prototyping (Framer, Rive, or code-based animation)
  • Familiarity with AI-assisted user research, synthetic testing, or automated design evaluation
  • Evidence of continuously adopting and mastering new tools — you have a pattern of being early to new workflows and making them productive fast
