Job Description:

The Fluent Design System team is redefining Microsoft 365’s design system for the AI era. As M365 Copilot evolves into a rich, multimodal productivity platform, Fluent is transforming from traditional design systems into an adaptive, model-aware design foundations—one that blends GUI precision with generative, context-aware behaviors at scale. As a Principal Design System Architect, you'll help shape the future of how AI-native experiences are designed, built, and sustained at an ecosystem-level. This role sits at the intersection of design, engineering, and emerging AI systems, with direct influence over the patterns, primitives, and architectural decisions that power M365 Copilot and the broader Microsoft ecosystem.

Job Responsibility:

  • Explore and apply emerging AI tools (LLMs, prompting workflows, generation pipelines, evaluation loops) as part of the default design-system workflow
  • Prototype and build practical utilities that accelerate concept → shippable system artifacts (components, tokens, documentation, integration workflows)
  • Define how AI models interface with Fluent libraries and foundations
  • Define system architecture and scalable foundations across tokens, components, documentation, and usage patterns
  • Establish lifecycle standards for design system assets
  • Create durable “ways of working” that keep design intent aligned with implementation
  • Translate product experimentation into reusable system primitives
  • Partner with Engineering and PM to define long-term design-system strategy and sequencing
  • Drive clarity around architectural decisions, governance, and adoption models
  • Make hard-to-undo decisions visible, testable, and scalable
  • Lead cross-discipline reviews and workshops to align designers and engineers around system-level decisions
  • Raise the overall craft and technical fluency of the organization

Requirements:

  • Master's Degree in Industrial Design, Product Design, Human Computer Interaction, User Experience, Interaction Design, or related field AND 6+ years experience working in product or service design
  • OR Bachelor's Degree in Industrial Design, Product Design, Human Computer Interaction, User Experience, Interaction Design, or related field AND 8+ years experience working in product or service design
  • OR equivalent experience
