Full Stack Developer (Contact Center AI)

Job Title: Full Stack Developer (Contact Center AI) Location: Brampton, ON (Onsite) Type: Contract 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. 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 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. Job Description • 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. We are an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees
