=============================


I am looking for an experienced AI Automation Engineer to build a scalable content production system that generates social media content, illustrations, and marketing assets for multiple brands.

The solution will use n8n as the orchestration platform together with AI models, Canva templates, and cloud storage.

This is not a simple automation project. I am looking for someone who can design a reusable production pipeline that can eventually generate hundreds of high-quality marketing assets every month.

The system should support multiple brands, including:

VaultGrid (Cybersecurity)
AI Graphics Programme
MedulaWorks
Additional brands in future

Each brand will have its own templates, colours, logos, and style guides.
