Principal Design Technologist

Design Patterns & AI Semiotics (Primary Focus) System Design: Deconstruct agentic AI systems into core functional subsystems (Reasoning, Perception, Action, Learning) and define the reusable patterns that govern them. Interaction Semiotics: Architect the "Sign Systems" for AI, defining how agents signal state, "thought process," and confidence. Establish standards for AI visual identifiers and conversational turn-taking. Clarity of Thought: Establish requirements for "Explainable Rationale," ensuring every agent's action is grounded in a rule, preference, or prior user action. Ensure that agents can reason for "when and how" to use specific business skills, maximizing intent fulfillment. AI Fluency Champion: Act as a force multiplier for the organization by upskilling designers, PMs, and cross-functional partners in AI tooling, prompt engineering, and agentic development patterns. Design System Evolution: Drive the evolution of design systems into "intelligent systems." Ensure that all components, tokens, and icons are machine-readable and ready for agent-led composition. Governance and Trust: Champion the principles of "Responsible AI." Ensure that all agentic experiences are built atop an enterprise-hardened foundation of governance, identity, and privacy.
