IG Group operates a scale fintech business spanning four consumer brands with access to 19,000+ financial instruments. The tech stack reveals a mature, data-intensive operation: Java/Spring backend, Kafka for streaming, Oracle + MongoDB persistence, React/React Native for client surfaces, and cloud infrastructure on AWS and GCP. Active adoption of Claude, GitHub Copilot, and Model Context Protocol signals aggressive AI-driven developer workflow automation — a strategic move to unblock legacy modernization bottlenecks that currently constrain shipping velocity.
