Experience developing visual workflow builders or graph-based editors (e.g., d3.js, React Flow)
Knowledge of real-time UI deployment for live agent monitoring/debugging
Familiarity with agentic AI concepts and their UI/UX requirements
Proficiency in frontend testing, performance profiling, and accessibility best practices
Understanding of secure UI patterns (SSO/OAuth2, RBAC, multi-tenant UI isolation)

Nice To Haves

Experience building low-code/no-code interfaces for AI or developer platforms
Familiarity with LangSmith and agent observability tooling integration in UI workflows
Exposure to conversational UI/UX design for chat and voice assistants
Prior experience with real-time collaborative editing (CRDTs, Yjs, or similar frameworks)
Startup or early-stage product development experience in AI-driven SaaS environments

Responsibilities

Agentic UI Development
Build interactive visual editors (drag-and-drop) for agent orchestration and reasoning workflows (LangGraph visualization).
Implement prompt management, versioning, and testing interfaces for agent development.
Develop real-time debugging tools to visualize agent reasoning traces, tool invocations, and dialog flows.
Integrate UI components with LangSmith APIs for agent observability, evaluations, and regression testing.
User Simulation & Testing Interfaces
Implement user simulation frameworks for testing agent strategies with varied personas and scenarios
Build A/B testing dashboards for evaluating outcome-driven strategies across agents and prompts.
Create UIs for multi-turn conversation playback, agent state inspection, and scenario-driven outcome analysis.
Dialog Orchestration & Multi-Channel Experience
Develop dialog flow editors to design multi-turn conversations with branching, context retention, and hierarchical dialogs.
Build deployment interfaces to configure assistants across digital channels (chat, web, messaging) and voice/IVR systems
Core UI Framework & Architecture
Collaborate with the architect to define frontend design patterns, state management, and modular UI frameworks.
Integrate frontend with backend APIs, agent runtimes, and real-time event streams.
Ensure UI scalability, performance optimization, and secure multi-tenant design for enterprise usage.
Collaboration & Developer Experience
Partner with backend engineers to integrate APIs and orchestration services into the UI seamlessly.
Work closely with UX designers to deliver high-quality, intuitive user interfaces aligned with AI/agent workflows.
