Responsibilities
Own end-to-end delivery of user-facing features across investigative, assistive, and summarization surfaces - from proof-of-concept to launch and iteration
Design interactive dashboards, timelines, and graph/entity views that handle high-volume, streaming data with intuitive drill-downs and filtering
Build resilient real-time UX (e.g., WebSocket/SSE) and a scalable state architecture for conversations, incidents, and tickets, with reliable cross-view synchronization
Define clear API/data contracts, contribute to backend endpoints as needed, and integrate enterprise systems (ticketing, knowledge bases, telemetry/observability, workflow tools)
Implement trustworthy AI UX: streaming responses with citations, guardrails/redaction, and human-in-the-loop review; capture feedback to improve prompts and behaviors
Instrument and improve outcomes - latency, error rates, summary accuracy, and user satisfaction - to reduce time-to-response and time-to-resolution
Work closely with backend, AI, product and design teams to translate complex requirements into elegant UIs
Mentor engineers, lead design reviews, and evolve coding standards and best practices
Communicate tradeoffs and architecture decisions clearly to technical and non-technical stakeholders

Experience with server-rendered web apps and routing
Strong grasp of state management patterns (e.g., state containers, signals, or equivalent)
Proficiency with async data fetching and caching for server state (e.g., query/fetch layers)
Advanced CSS skills (responsive layouts, design systems, accessibility)
Experience with real-time transports (e.g., WebSocket, Server-Sent Events) and streaming UX

Built user experiences for generative AI features (assistive workflows, agent-style tool use, or similar)
Understanding of LLM streaming patterns, tool orchestration, and structured outputs (citations, functions)
Familiarity with retrieval-augmented generation, prompt strategies, evaluation, and guardrail techniques
Experience visualizing reasoning traces, tool execution, and confidence signals for user trust
Real-time collaboration (presence, concurrency control, CRDTs/OT)
