Principal Design System Architect
Microsoft
What You’ll Do
- Architect AI-Native Design Systems: Define and evolve the core design system architecture that supports generative UI, adaptive layouts, multimodal input/output, and model-driven behaviors—ensuring Fluent scales across platforms, products, and future Copilot experiences.
- Bridge Design and Systems Thinking: Partner deeply with engineering, PM, and research to influence how backend services, LLM capabilities, and system constraints shape front-end design patterns. You’ll help translate AI capabilities into usable, reliable, and human-centered design primitives.
- Design Like a Maker: Prototype early and often—using code, design tools, and AI workflows to test ideas, explore new interaction models, and pressure-test system assumptions. You’re comfortable working across prompts, components, tokens, and abstractions to move ideas forward.
- Set Long-Term Direction: Identify the design system decisions that matter most over a 6–12 month horizon. You’ll help Fluent stay ahead of delivery by researching, experimenting, and defining future-facing patterns while the broader team focuses on execution.
- Scale Through Influence: Raise the technical and systems fluency of designers across Microsoft by coaching, documenting frameworks, and shaping shared mental models. Your impact is felt not just through what you build, but through how others build with Fluent.
- Champion Craft, Quality, and Coherence: Advocate for clarity, accessibility, performance, and design excellence in a rapidly evolving AI landscape—ensuring that innovation never comes at the cost of trust or usability.
Why This Role Matters
Responsibilities
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.
