The Elastic IT team is shifting beyond standard chat interfaces to craft the next frontier of generative and agentic AI experiences. We are looking for an innovative UX Engineer to join our team to bridge the gap between powerful AI capabilities and intuitive, delightful user interfaces that accelerate productivity across the entire organization.

• Translate complex generative and agentic AI processes into intuitive, responsive, and engaging front-end interfaces.
• Design, build, and maintain scalable, accessible, and reusable front-end UI component libraries for generative AI interactions using modern frameworks like React and TypeScript.
• Prototype and implement novel interaction patterns for conversational AI, agent execution visibility (thought logs, tool calls), prompt systems, and rich dynamic outputs.
• Optimize UI performance for real-time AI responses, managing token streaming latency, async state management, and optimistic UI updates.
• Connect front-end interfaces to internal services, including Retrieval Augmented Generation (RAG) endpoints, Elasticsearch Relevance Engine (ESRE), and agent orchestration APIs.
• Partner closely with UX designers, product managers, and AI backend engineers to iteratively test and refine AI workflows based on real user feedback.
• Ensure all front-end interfaces strictly adhere to web accessibility standards (WCAG) and align seamlessly with Elastic's core design system (EUI).
• Implement front-end tracking to monitor user satisfaction, prompt effectiveness, interaction latency, and interface usability.
• Maintain comprehensive documentation for UI component systems, front-end architecture, and design pattern guidelines.

• Recent experience creating user interfaces for GenAI applications, including conversational interfaces, dynamic prompt builders, and complex agent workflows.
• Deep expertise in modern TypeScript, JavaScript, React, HTML5, and CSS/Sass, with an emphasis on modular architecture.
• Deep experience managing complex asynchronous UI state, WebSockets, and Server-Sent Events (SSE) for streaming LLM responses.
• Proficient background or active practice in user experience design, wireframing, design systems, and rapid prototyping.
• A solid desire to learn and leverage the Elasticsearch Relevance Engine (ESRE), Elastic UI (EUI), and the broader Elastic ecosystem.
• Experience with integrating front-end systems with AI/LLM backend services and orchestration tools (e.g., LangGraph, REST/GraphQL APIs).
• Experience extending and contributing to enterprise design systems and component documentation tools like Storybook.
• Knowledge of web performance optimization techniques, cross-browser compatibility, and WCAG accessibility guidelines.
• Hands-on experience with modern design and handoff tools (e.g., Figma).
