Job Description:
Technical Architect – AI-Powered Self-Service Platform (Cloud + Agentic AI)
Role Overview
We are looking for a senior, hands-on Technical Architect to lead the design and delivery of a next-generation AI-powered self-service platform for a large enterprise client in the media and advertising sector. The platform enables users to move from a natural-language brief to a fully priced, bookable plan in minutes.
The solution is a containerised .NET Core + React application deployed on AWS EKS, integrated with the client's internal order management system (via async queue) and CRM (via custom APIs), augmented by a conversational AI agent hosted on GCP Vertex AI Agent Engine (Google ADK / LangGraph / Gemini).
The role blends enterprise application architecture, cloud-native engineering and Agentic AI design — ideal for a senior engineer-architect who has evolved from strong backend/full-stack roots into cloud + AI system design.
