Job Description

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 dynamic 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.

  • 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 varied 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.
  • Strong 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.
