Job Responsibility
Job Responsibility
  • 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
  • Agentic Prototyping and Codebase Exploration: Vibe-Code to Production: Lead the rapid prototyping of 0-to-1 agentic features directly within the production codebase. Use AI-native development environments (e.g., GitHub Copilot, Claude Code, Lovable) to iterate on complex UI/UX patterns that require real-time model integration
  • Functional Artifacts: Produce 'unsolicited provocations' and high-fidelity functional artifacts that challenge current product assumptions and reveal the technical constraints/opportunities of emerging LLMs
  • Bridge Design and Engineering: Partner with professional developers to ensure that 'vibe-coded' prototypes are translated into scalable, maintainable, and high-performance production features through clear Pull Requests (PRs) and technical documentation
  • Orchestration Design: MCP Architecture: Be familiar with the 'connective tissue' that allows agents to discover and utilize enterprise data across Dataverse, M365, and the Microsoft Graph
  • Tool Design: Design and optimize MCP tool descriptions, instructions, and schemas. Ensure that agents can reason for 'when and how' to use specific business skills, maximizing intent fulfillment
  • Pathway Design: Move beyond linear UI flows to design probabilistic 'pathways' for AI agents. Define how agents maintain memory, handle multi-step reasoning, and gracefully recover from non-deterministic failures
  • Model Evaluation and Performance Frameworks: Quality Benchmarking: Define and operationalize the quality bar for agentic experiences by translating UX principles - helpfulness, coherence, and instruction fidelity - into measurable evaluation frameworks. Co-create 'LLM-as-a-judge' systems that embed these standards into continuous, automated evaluation loops, enabling scalable, high-confidence iteration of AI-driven experiences
