6 MOnths The bridge between humans and AI, responsible for building interfaces and middle-tier services that make agentic systems transparent, intuitive, and responsive.

About the Role

You will design agile UIs for human-in-the-loop workflows, build backend microservices that safely route requests to AI systems, and manage complex state across multi-turn conversations and long-running agent tasks.

What You Will Do
AI-Native Interfaces: Build responsive UIs supporting streaming tokens (SSE), agent tool-use visualization, and real-time reasoning feedback.
API & Middle-Tier Development: Implement secure microservices that orchestrate requests across RAG, agents, and evaluation layers.
State Management: Handle complex frontend state for multi-turn conversations, agent workflows, and partial-completion tasks.
Performance Optimization: Ensure low-latency rendering and smooth UX across diverse AI response times.

Required Qualifications
Expertise in modern frontend frameworks (React, Vue) and backend runtimes (Java, Python).




Experience building chat interfaces or state-heavy dashboards.
Solid understanding of web security and API design.

Skillset Requirements
Frontend Engineering: React/Vue, component architecture, state management, and streaming UI patterns.
AI-Native UX: Designing interfaces for streaming tokens, agent tool-use visualization, and multi-turn reasoning.
Backend Microservices: Java/Python runtimes, secure routing, and API orchestration.
State Management: Redux, Zustand, Vuex, or equivalent for long-running agent tasks.
Web Security: OWASP, secure API design, auth flows, and safe AI request routing.
Performance Optimization: Low-latency rendering, concurrency handling, and streaming UI performance.
Event-Driven UI: SSE, WebSockets, and real-time agent feedback loops.
Integration with AI Backends: Handling varied response times, partial outputs, and agent state transitions.
Accessibility & Design Systems: WCAG-compliant, reusable component libraries for consistent AI-native UX.
