Principal Product Designer,AI Experiences in London

Overview Microsoft Superintelligence team's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. This role is part of Microsoft AI's Superintelligence Team. The MAIST is a startup-like team inside Microsoft AI, created to push the boundaries of AI toward Humanist Superintelligence — ultra-capable systems that remain controllable, safety-aligned, and anchored to human values. Our mission is to create AI that amplifies human potential while ensuring humanity remains firmly in control. We aim to deliver breakthroughs that benefit society — advancing science, education, and global well-being.

We are looking for a designer who builds. You'll own the end-to-end user experience for our most visible AI product surfaces — MM Labs, Playground, marketing pages, and model specification tools — taking concepts from rough sketch to polished, shipped product. This is not a role where you hand off mockups and wait. You will use AI-native tools and agentic coding workflows to move from Figma to working prototypes to production-quality frontend, compressing the traditional design-to-engineering handoff into a single, fast loop.

You come from a design background — you have strong graphic design instincts, a refined sense of aesthetic taste, and deep experience in interaction design. But you've also embraced the AI-native workflow revolution: you use tools like Cursor, GitHub Copilot, v0, or similar agentic coding assistants to prototype, iterate, and ship UI at a pace that would have been impossible two years ago. You're not a frontend engineer who picked up design — you're a designer who has dramatically expanded what you can deliver by leveraging AI. This is a small team that prizes ownership and craft. You will ship your own work, regularly. Your designs will be used by researchers, engineers, and external users interacting with frontier AI models. The bar for quality is extremely high, and the pace is fast.

Responsibilities

• 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.
• 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.
• 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.
• 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.
• 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.
• Inform design systems: Contribute to and extend shared design systems, component libraries, and interaction patterns — ensuring consistency across surfaces while pushing the craft forward.
• Drive design through data and user insight: Use both qualitative and quantitative signals (user research, analytics, A/B experiments) to validate design decisions and iterate. Bring evidence, not just intuition.
• Automate your own workflow: Continuously explore and adopt new AI tools, plugins, and workflows that make you faster and more capable. Share what you learn with the team.

Qualifications

Required Qualifications

• 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.

Preferred Qualifications

• 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.
